Performances of resource poor households in aquaculture practices in sadar up...AbdullaAlAsif1
The present study was conducted to evaluate the performances of resource poor farmers in fish farming at their homestead ponds in Sadar Upazila under Meherpur district from July to October 2015. Participatory Rural Appraisal tools such as questionnaire interview, cross check interview and secondary information were used to assess the performances in aquaculture activities. Thirty pond fish farmers were purposively selected, among them 10, 5, 5, and 10 participants were involved with carp-mola, carp-tilapia and carp-shing polyculture and vietnam koi mono-culture respectively. The result showed that the majority of the farmers (33.33%) had 51-100 decimal cultivable land followed by 20 and 16.67% participants who possessed 151-200 and >300 decimal of land respectively. It was found that the highest percentage of participants (73.33%) primary occupation was agriculture followed by fish farming (3.33%). A majority of the farmers (53.33%) started fish farming only before 1-5 years influenced by the positive result of fish culture by the villagers and 20% each have started before 6-10 and 11-15 years back. Only 6.67% farmers started fish culture in 16 years before who were the pioneers of fish farming in the region. The average pond size in the area was found 15 decimal with a range of 7 to 35. Before starting fish culture all the farmers got training and inputs support for fish culture from a local NGO called Daridra Bimochon Sangstha (DBS). Prior to start fish farming all of the farmers followed standard procedure of pond preparation and fish fry release in their ponds. Majority farmers (90%) applied homemade feed, whereas rest applied commercial feed to their fish. By contrast, 90% farmers used to feed their fish and rest was reluctant to provide feed to the fish. Almost twenty seven percent respondents annual income was between BDT 61,000 to 80,000 followed by 20 and 10% whose income was 100000-150000 and >150000 BDT per year.

The survey revealed that average pond size was 0.48 ha with 40% of the farmers having ponds of single ownership, 20% having ponds of multiple-ownership, 30% having ponds of single lease and 10% having ponds of multiple leases. Poly culture of Indian major carps and exotic carps has been practiced by most of the farmers. Fish fingerlings were stocked from April to June and average stocking density was 12,370 fingerlings/ha. The average fish production cost was Tk 69,870/ha/yr. Although the living condition of the rural fish farmers were poor, livelihood outcomes were found positive and 88% of the farmers have improved their socioeconomic conditions through fish farming. The gross income and net profit were Tk. 1, 06,400 and Tk. 1, 00,000/ha/yr respectively. The average monthly income was in range of BDT 15,000-25,000. Their basic need like food, cloth, house, education and medical facility had changed after fish farming. The households have broadly improved their food consumption, family education, standards of living, purchasing power, choice and economic ability through fish farming. The constraints for sustainable pond fish farming in the areas were lack of technical knowledge of the farmers, disease of fishes, multiple ownership of the pond, higher production cost (mainly seeds and feed), insufficient supply of fry and fingerlings, lack of money and credit facilities and inadequate extension services. It is therefore essential to provide the necessary training facilities with institutional and organizational supports, credit facilities and extension services for sustainable fish production and livelihoods of rural fish farmers.

Primary data were collected from 15 fish farmers for the study during the period from June to November, 2016. Production performance of three stocking package were compared. CFP-1 package contained Thai sarpunti (24700/ha) + Tilapia (6175/ha); CFP-2 comprised of Thai sarpunti (24700/ha) + Common carp (6175/ha); while CFP-3 was represented by Thai sarpunti (24700/ha) + (Tilapia (6175/ha) + Common carp (6175/ha). Both tabular and functional analyses were used to achieve the objectives of the study. Fish productions in paddy fields are profitable business. The total cost of fish production under three selected stocking plans such as CFP-1, CFP-2 and CFP-3 were estimated to be Tk. 73085, Tk. 83459 and Tk. 86928 per ha, respectively. The corresponding total gross return (Tk./ha) were Tk. 209777, Tk. 274170 and Tk. 262721, respectively. The benefit cost ratio (BCR) was estimated to be 2.87, 3.28 and 3.02 for package-1, package-2 and package-3, respectively. Returns over per taka investment (NR/Tk.) were found to be 1.32, 1.69 and 1.42 for the above fish culture packages. Cobb-Douglas production function analysis indicated the positive contribution of fish fingerlings, fertilizer, fish feed and lime on the total income and farm productivity, while human labor and bank interest rate decreased the farm income. The values of R2 were 0.775, 0.739 and 0.812 for CFP-1, CFP-2 and CFP-3, respectively. About 77.5 percent, 73.9 percent and 81.2 percent of variation in yield and gross return of fish production in paddy fields could be explained by the multiple regression equations. Fish production in paddy fields are economically profitable, viable and environment friendly. The farmers may undertake fish culture in paddy fields if suitable paddy fields are available.

Most of farms (96%) are under polyculture, while only 4% is under monoculture practice. The source of pangasiid fingerlings were fry traders, nearby nursery, local hatchery and large hatchery from Jessore. Fingerlings size varied from 1 to 2 inch with price of TK. 0.5-1/fingerling. Majority of the farmers stocked fingerlings in March to April with average stocking density was 18,700 fingerlings/ha. About 46% of Pangasius farmers have leased ponds and lease value varied from Tk. 1,12,200-1,49,600/ha/yr. The leased ponds were solely used for Pangasius farming. Over 19% of farmers exchanged water one time per year, while 81% never exchanged. Almost all of the Pangasius farmers used supplementary feeds in their farms. Among the farmers, 37% of farmers received general aquaculture training from Bangladesh Fisheries Research Institute (BFRI) and Department of Fisheries (DoF) and some non-government organizations (NGO's). Average pond size was 0.17 ha of which 85% was perennial and 15% was seasonal. Various constraints such as, lack of capital and proper technological knowledge, lack of continuous supply of quality fry, high price of the inputs especially feed, adulteration of feed, inbreeding, improper marketing and management problems were prominent. Some farmers use some unethical feeds in their farms. The highest proportion (41%) of the people was involved in Pangasius farming as main occupation and their age was between 31-40 years. The main reason of converting their ponds and lands for Pangasius farmimg was to get more profit. Large farmers always got higher profit over 2.03 Lac Tk./ha. However, small and medium farmers also got over 1.9 lac Tk. profit per hectare from Pangasius farming. Though the potential of fish farming in Jhikargacha region is mentioned-worthy, it is currently facing a number of problems such as, lack of capital, proper technological knowledge, lack of regular supply of quality fingerlings, improper proportion of protein and supply of adulterate feed, high price of feed, inbreeding, marketing and management problems. If the suggested constraints could be solved, the fish production in Jhikargacha region would possibly be increased tremendously and the pangasius farming would be progressed towards sustainability.
Growth and production performance of Vietnamese koi (Anabas testudineus) with...AbdullaAlAsif1
A culture experiment was conducted to see the growth and production performance of Vietnamese koi (Anabas testudineus) with Magur (Clarias batrachus) at different stocking densities in a farmer's ponds under semi-intensive rearing system for a period of 120 days. The experiment was conducted in three ponds at Rahmatpur of Muktagachha Upazila of Mymensingh district from 5 August to 5 December, 2013. The size of ponds were 24 (T 1), 24 (T 2) and 24 (T 3) decimal with an average depth of 4 feet. Three different stocking densities were tested, namely treatments T 1 (400 fish /decimal, 350 Vietnamese koi and 50 magur); T 2 (450 fish /decimal, 400 Vietnamese koi and 50 Magur) and T 3 (550 fish /decimal, 500 Vietnamese koi and 50 Magur). Ruposhi Bangla feed was used in all treatments two times daily from the beginning of the fry stocking. The initial weight of Vietnamese koi and Magur were 5±0.00 g and 2±0.00 g respectively. The initial length of Vietnamese koi and Magur were 2.54 and 3.50 cm respectively. The average highest final weight gain of Vietnamese koi was (138.71±0.03 g) observed in T 1 and followed by T 2 (135.65±0.12 g) and T 3 (129.29±0.49 g). Similarly, the average highest final weight gain of Magur (76.00±0.58 g) was observed in T 1 and followed by T 2 (68.36±0.43 g) and T 3 (62.61±0.58 g) respectively. The average highest final length gain of Vietnamese koi (17.38±0.05 cm) was observed in T 1 and followed by T 2 (17.00±0.04 cm) and T 3 (16.33±0.03 cm). Similarly, the average highest final length gain of Magur (21.30±0.09 cm) was observed in T 1 and followed by T 2 (17.00±0.05 cm) and T 3 (15.87±0.02 cm) respectively. The survival rate of the stocking Vietnamese koi and Magur were recorded 95.14 and 72.00 % in T 1 ; 93.25 and 64.00% in T 2 ; 90.80 and 68.00 % in T 3 respectively. Fish production in T 1 , T 2 and T 3 were 48.93; 52.79 and 60.83 kg/decimal/120 days, respectively. The total production of T 3 was increased with the increasing of stocking density compare to T 2 and T1. The benefit-cost ratio (BCR) was higher in T 3 where BCR was 1.67 and on the other two treatments BCR was 1.53 in T 2 and 1.52 in T 1 although the highest production was obtained in T 3 but individually growth performance of Vietnamese koi and Magur were higher in T 1. Based on the result of the present experiment, farmers could be suggested to rear Vietnamese koi with Magur at the stocking density of 550 fish/decimal (500 Vietnamese koi and 50 Magur) which was the highest density tried to get more production and financial benefit. Further experiment need to be conducted by taking higher density than the 550 fish/decimal for the optimization of stocking density to get more production and benefit.
Analysis of technical and financial efficiency of intensive white leg shrimp ...AI Publications
The objective of this investigation was to evaluate the technical and financial effectiveness of the current intensive culture of white leg shrimp (Litopenaeus vannamei) in Tien Giang province, Vietnam. A survey was conducted from December 2021 to April 2022 to collect data from shrimp farms in the Go Cong Tay district, which is a planned area of this province for brackish shrimp farming. The results showed that, in terms of technique, most farmers have a lot of experience and a high level of application of science and technology. The average size of the culture pond (0.26 ha pond–1), stocking density (78.83 ind. m–2), survival rate (85.28%), FCR (0.26), and harvested shrimp size (58 ind. kg–1) were similar to other Mekong Delta provinces. There were significant differences in the incomplete water sedimentation and treatment ponds and the major use of groundwater for shrimp farming. In terms of finance, the mean yield was 12,345.97 kg ha–1 crop–1 and was higher than other provinces in the Mekong Delta. However, the mean profit and the total profitability were 17,575 USD ha–1 crop–1 and 0.38, respectively, which was lower than the previous year in the Tien Giang province because of the high input costs. The results of this study show the necessary requirements for the sustainable development of the model of intensive shrimp farming in Tien Giang Province, including (1) the complete rebuilding of the system of farming, water sedimentation, and treatment ponds; (2) the efficient solution for using the surface water; and (3) the support of local authorities, aiming to help farmers reduce input costs and increase profits.

Growth and production of near threatened Ompok pabda (Hamilton) were examined at different feeding frequencies in the present study. The experiment was conducted for four months in three earthen ponds from 1 st April to 31 st July 2018 at Tanore Upazila in Rajshahi district, Bangladesh. The experiment was performed using pabda, (Ompok pabda) fingerling (average) to study the effect of feeding frequency on growth performance. The study carried out considering three treatments, namely T 1 , T 2, and T 3 ; while the feeding frequency was two times per day in treatment T 1 , three times per day in treatment T 2, and four times per day in treatment T 3. Fish were fed considering three-stage of life span; these were fingerling stage, early growing stage, and growing stage. In the fry stage, the fishes were fed 20% feed, in the fingerlings stage the fish were fed 10% feed and in the growing stage, the fish were fed 8% feed of the body weight. The mean water temperature ranged between 27.13±2.10 and 27.29±2.16 °C among treatments, while water transparency ranged between 31.91±1.58 and 29.96±1.84 cm. pH ranged between 7.62±0.14 and 7.70±0.19; while the mean dissolved oxygen was ranged between 5.35±0.11 and 5.56±0.14 among treatments. The final weight gain was found to be highest (56.36±0.01) in the treatment T 2 and lowest (38.23±0.01) in the treatment T 3. The SGR value was higher (3.94±0.01) in the treatments T 2 followed by treatments T 1 and T 3. Net weight gain was significantly (p<0.05) higher in feeding frequency three (56.36±0.1), followed by feeding frequency four (38.23±0.1) and feeding frequency two (40.67±0.73). The FCR value ranged between 1.90 and 2.87 among treatments. The growth performance and specific growth rate were significantly (p<0.05) higher in feeding frequency three. The highest (4049.1±0.1 kg/ha/120 days) production was observed in T 2. Best cost benefit ratio was gained in treatment T 2 .

The study was conducted to evaluate the present status of the production of traditional fermented fish product-shidal (Chapa shutki or shidol) in Lalpur, Ashuganj Union, Brahmanbaria district and its ecological implication and value chain during June to November, 2016. Shidal is produced by natural fermentation process of fresh water punti and marine phaisha and poa fish during winter (October to January). It was found that the Shidal production from freshwater fish in Lalpur has been shrinking gradually due to a decline in fish production from the Meghna River Basin and low supply of raw fishes from others areas. The fishers noted the local extinction of large numbers of once common fish with a gradually low supply of punti and a declining average size among the fishes that are still captured. It was found that not only the total volume of catch decreased but there have been a marked decline in catch per unit effort (CPUF) over the last ten years. During the fermentation season, every day 2-4 ton of raw punti are sold in Lalpur Fish Landing Center and the price of punti varies with grade, season and quality. On an average 4 kg of fresh punti produces 1.2 kg of dry punti and 1.2 kg of dry punti produces 1.44 kg of shidal. It was observed that there were two types of punti used for making shidal in Lalpur-with scales and without scales. The prices of shidal were Tk 800/kg, Tk 500/kg, and Tk 500/kg produced from punti, poa and phaisha, respectively. There are nearly 250 dangaries (fish processing place) for Shidal production and each of the danagaries produce 100-150 motkas (each motka contains 36-40 kg of shidal) of shidal in a season. One motka is sold in Tk. 20,000-24,000 when there is no salt used but Tk. 16,000 per motka when salt is used. It was found that around 2000 people were employed in Shidal production and another 200 people worked in filling in the motka in Lalpur. No chemical are used to make Shidal but some salt is applied during Shidal processing. It was observed that there was no fixed marketing channel for Shidalshutki. Seventy percent (70%) of the Shidal are produced for the domestic market. Shidal produced from small sized punti are exported to India but Shidal produced from marine fishes has never been exported. Although people prefer Shidal made from punti, but due to its gradual disappearance from the natural water bodies, they are forced to consume Shidal prepared from marine poa or phaisa.
Impact of shrimp cultivation on agriculture: A study in Parulia union of Satk...Agriculture Journal IJOEAR
Abstract— Transformation of land use pattern from agriculture to massive shrimp cultivation has been taking place in the coastal areas of Bangladesh. The present study attempts to find out various impacts associated with shrimp cultivation in Parulia union of Debhata upazila, Satkhira. A three months long field study was carried out in 2014 in twelve villages of the unions under study. The data were collected through a combination of qualitative and quantitative approaches: questionnaire surveys, focus groups discussions (FGD), field observation, key informants interview (KII) and secondary materials. The research revealed that shrimp cultivation has direct impact on agriculture in the study location. Though the traditional occupation of people in the area was agriculture (98%, N=102), however, after introduction of commercial shrimp cultivation (approximately 20 to 25 years ago) people in the area are overwhelmingly engaged in shrimp cultivation (86%, N=72). Due to encroachment of agricultural land by shrimp farm present land use strategies in the studied area have also changed drastically. Presently only 42.2 percent of respondents own agriculture land (N=102) whereas about 91.2 percent of respondents (N=102) own gher in the study area. Average agriculture land of respondent households in the area has also been reduced from 3.37 bigha to 1.45 bigha, whilst area and number of ghers of respondent households are increasing. Out of 44.16 km2 of land in the study area 32.66 km2 are under shrimp/bagda cultivation and only 4.19 km2 (Boro cultivation = 3.50 km2 and other crop cultivation = 0.69 km2, Table 8) are now being used for agriculture. With the increase of shrimp cultivation soil salinity is also increasing, as a result most the agriculture land becomes infertile and ultimately crop yields become reduced. Local rice varieties such as Patnai; Durgavogh; Kartikshail; Nagirshail; Chinikanai; Lalgati; Dhungati; Ashfali; Balam; Boran; Jamaibabu etc. are not able to cope with the excessive soil salinity, as a result farmers have to cultivate salinity tolerant high yielding varieties such as Jamaibabu 10; Aftab 1-10; BIRI 28, 30, 41, 47; BINA 7, 8, 10, 22, 28; Minikat; ACI 1, 2; Hira; Akhter 6; Sakti; Sathi; Aloron; Aata 70 etc.

The present study was conducted to assess the livelihood status of fish fry and fingerling traders and socioeconomic condition in the greater Jessore, Bangladesh from April 2013 to September 2013. Data were collected through the use of well-structured questionnaire from the selected area. 73% of traders have single family but only 27% have joint family. 45% fish fry and fingerling traders family has four members. 20% family has five members, 14% family has six members, 12% family has three members 9%family has seven to eight members respectively. 92% traders has own bank account but only 7% traders uses their bank account when they trade fry and fingerling. 87% traders have secondary business like rickshaw business, fruit business, cloth business, fish trading etc. Among 300 fish fry and fingerling traders the sanitation facilities are present 100%. It was found that 69% and 31% of fish farmers used semi-pucca and pucca toilet respectively. Among 300 fish fry and fingerling traders 78% of traders have own house but only 22% of trader live in rental house or place. 46% of traders have institutional education that range from primary to higher education and other 54% of traders have no experience in education. In case of illness 58% of traders and trader's family goes to government hospital, 24% uses private clinic, 15% traders are uses local village doctor and another 3% does not get any treatment or not require no treatment. 93% traders have television, 5% house consist radio and another 2% house no instrument for entertainment. Only 10% trader wants their son and grandson engages with this fish fry and fingerling trading profession. The average monthly income of traders in the peak season is 18000 taka and off-peak season the income is less than 7000 taka per month.

In order to understand the present status of hatcheries, questionnaire interview and participatory rural appraisal tools were used in North-west Fisheries Extension Project (NFEP), Parbatipur during the period from July to December 2015. There are two hatcheries in NFEP, Parbatipur- a carp hatchery and a prawn hatchery. The production of spawn was around 611 kg in the year 2015. According to the target hatchery manager collected brood fish from rivers and other sources which he maintained in their brood stock ponds with proper management. The hatchery manager maintained proper age and weight of broods for spawning and followed the guideline of hatchery operation so that the quality of spawn and fry were good. It was found that the hatcheries produced fish seed of a variety of species such as Indian major carps, carpio, sarpunti, silver carp, grass carp, magur, shing as well as freshwater prawn. The hatchery production activities took place starting from February and continued up to September. The quantity of fish seed produce varied from 25 to 75 kg per hatching cycle depending on size and facilities of hatcheries. The price of fry in NFEP was being fixed by the hatchery manager. However, the price variation was seen due to seasonal variation, species and demand. The average price of fish seed was highest in monsoon and lowest in winter. A number of middlemen were involved in the fry marketing channel of NFEP at Parbatipur. They were responsible for increasing the price of fry at each stage of marketing channel.

Socio-Economic and Environmental Implication’s of Shrimp Cultivation in Andhr...Ruby Med Plus
Impromptu and random expansion of shrimp cultivation is happening in coastal regions of Andhra Pradesh. The exploration of its adverse effects has not received significant attention from the Indian researcher community yet. The shrimp industry is polluting and degrading soils,
water, mangroves, and forests. The sustainable productivity of ecosystems, biodiversity and public health is endangering year after year. Shrimp aquaculture is changing customary patterns of natural resource use by appropriating these resources for its own purposes while restricting rights of local users as coastal Andhra big and experienced farmers in the aqua field are making huge investments in the sector and purchasing the agriculture fields of small farmers to convert it into aqua ponds. This in turn affects livelihoods more widely by disrupting earlier systems of production, distribution and social relations.
In order to elicit the concomitant socio-economic impacts and propose environmental sustainable solutions of shrimp cultivation based on secondary data, the present study was conducted by applying ‘Systematic Review and Content Analysis’ as a research method. The study findings manifest that the constant and unregulated shrimp farming has immense impacts on human health, ecology, environment and sustainability other than economic benefits to aqua farm
owners. The extensive shrimp farming in coastal areas of Andhra Pradesh has negatively expedited the infringement of mangroves, intrusion of salinity, degradation of land, destabilization of coastal ecosystems. The main socio-economic effects challenge the patterns of
livelihood pattern, displacement of family and social structure, internal migration, reduction in grazing field and livestock, changes in the cropping calendar and its pattern and bio-diversity.
The Government of Andhra Pradesh and the financial institutions sponsoring shrimp cultivation has overlooked the impact of shrimp farming on Ecological and sustainability of farm fields and
control of salinity and degradation of mangrooves. In conclusion, appropriate adoption and implementation of the resilient strategies can reduce the adverse effects on the coastal environment, and improve the impact of unplanned shrimp cultivation in Andhra Pradesh and
other parts of India.
Unlocking the mysteries of reproduction: Exploring fecundity and gonadosomati...AbdullaAlAsif1
The pygmy halfbeak Dermogenys colletei, is known for its viviparous nature, this presents an intriguing case of relatively low fecundity, raising questions about potential compensatory reproductive strategies employed by this species. Our study delves into the examination of fecundity and the Gonadosomatic Index (GSI) in the Pygmy Halfbeak, D. colletei (Meisner, 2001), an intriguing viviparous fish indigenous to Sarawak, Borneo. We hypothesize that the Pygmy halfbeak, D. colletei, may exhibit unique reproductive adaptations to offset its low fecundity, thus enhancing its survival and fitness. To address this, we conducted a comprehensive study utilizing 28 mature female specimens of D. colletei, carefully measuring fecundity and GSI to shed light on the reproductive adaptations of this species. Our findings reveal that D. colletei indeed exhibits low fecundity, with a mean of 16.76 ± 2.01, and a mean GSI of 12.83 ± 1.27, providing crucial insights into the reproductive mechanisms at play in this species. These results underscore the existence of unique reproductive strategies in D. colletei, enabling its adaptation and persistence in Borneo's diverse aquatic ecosystems, and call for further ecological research to elucidate these mechanisms. This study lends to a better understanding of viviparous fish in Borneo and contributes to the broader field of aquatic ecology, enhancing our knowledge of species adaptations to unique ecological challenges.

The present study was conducted in the selected Malotipur village of Muktagachha upazila under Mymensingh district during 13 to 28 April, 2014. The sample size of the study was 90 fish farmers (43 percent of population) and it was drown from a population of 209 using simple random sampling technique. Eight (8) selected characteristics of farmers viz.: age, level of education, family size, farm size, annual income, credit received, training experience and cosmopoliteness were considered as the independent variables, while the attitude of the farmers towards Pangas farming was the dependent variable of the study. The focus variable i.e. attitude of farmers towards Pangas farming was measured with a 5 point likert scale such as " strongly agree " , " agree " , " undecided " , " disagree " and " strongly disagree " in Pangas farming and the corresponding scores were 5, 4, 3, 2 and 1 respectively. The findings indicated that the majority (50 percent) of the Pangas farmers had moderately favorable attitude towards Pangas farming compared to 31.1 percent having highly favorable and only 18.9 percent had slightly favorable attitude. The finding on problem faced by the farmers related to Pangas farming revealed that about two-third (65.6 percent) of the farmers had high problem followed by 20 percent low problems. Among eight selected characteristics of Pangas farmers five characteristics such as age, level of education; annual income, training experience and cosmopoliteness had significant positive relationships with their attitude towards Pangas farming. On the other hand, the other two characteristics of pangas farmers such as family size and farm size had positive but no significant relationships with their attitude towards Pangas farming.

The research was carried out through questionnaire interview with randomly selected 80 farmers during December 2014 to May 2015. Most of farms (96%) are under polyculture, while only 4% is under monoculture practice. The source of pangasiid fingerlings were fry traders, nearby nursery, local hatchery and large hatchery from Jessore. Fingerlings size varied from 1 to 2 inch with price of TK. 0.5-1/fingerling. Majority of the farmers stocked fingerlings in March to April with average stocking density was 18,700 fingerlings/ha. About 46% of Pangasius farmers have leased ponds and lease value varied from Tk. 1,12,200-1,49,600/ha/yr. The leased ponds were solely used for Pangasius farming. Over 19% of farmers exchanged water one time per year, while 81% never exchanged. Almost all of the Pangasius farmers used supplementary feeds in their farms. Among the farmers, 37% of farmers received general aquaculture training from Bangladesh Fisheries Research Institute (BFRI) and Department of Fisheries (DoF) and some non-government organizations (NGO's). Average pond size was 0.17 ha of which 85% was perennial and 15% was seasonal. Various constraints such as, lack of capital and proper technological knowledge, lack of continuous supply of quality fry, high price of the inputs especially feed, adulteration of feed, inbreeding, improper marketing and management problems were prominent. Some farmers use some unethical feeds in their farms. The highest proportion (41%) of the people was involved in Pangasius farming as main occupation and their age was between 31-40 years. The main reason of converting their ponds and lands for Pangasius farmimg was to get more profit. Large farmers always got higher profit over 2.03 Lac Tk./ha. However, small and medium farmers also got over 1.9 lac Tk. profit per hectare from Pangasius farming. Though the potential of fish farming in Jhikargacha region is mentioned-worthy, it is currently facing a number of problems such as, lack of capital, proper technological knowledge, lack of regular supply of quality fingerlings, improper proportion of protein and supply of adulterate feed, high price of feed, inbreeding, marketing and management problems. If the suggested constraints could be solved, the fish production in Jhikargacha region would possibly be increased tremendously and the pangasius farming would be progressed towards sustainability.
Growth and production performance of Vietnamese koi (Anabas testudineus) with...AbdullaAlAsif1
A culture experiment was conducted to see the growth and production performance of Vietnamese koi (Anabas testudineus) with Magur (Clarias batrachus) at different stocking densities in a farmer's ponds under semi-intensive rearing system for a period of 120 days. The experiment was conducted in three ponds at Rahmatpur of Muktagachha Upazila of Mymensingh district from 5 August to 5 December, 2013. The size of ponds were 24 (T 1), 24 (T 2) and 24 (T 3) decimal with an average depth of 4 feet. Three different stocking densities were tested, namely treatments T 1 (400 fish /decimal, 350 Vietnamese koi and 50 magur); T 2 (450 fish /decimal, 400 Vietnamese koi and 50 Magur) and T 3 (550 fish /decimal, 500 Vietnamese koi and 50 Magur). Ruposhi Bangla feed was used in all treatments two times daily from the beginning of the fry stocking. The initial weight of Vietnamese koi and Magur were 5±0.00 g and 2±0.00 g respectively. The initial length of Vietnamese koi and Magur were 2.54 and 3.50 cm respectively. The average highest final weight gain of Vietnamese koi was (138.71±0.03 g) observed in T 1 and followed by T 2 (135.65±0.12 g) and T 3 (129.29±0.49 g). Similarly, the average highest final weight gain of Magur (76.00±0.58 g) was observed in T 1 and followed by T 2 (68.36±0.43 g) and T 3 (62.61±0.58 g) respectively. The average highest final length gain of Vietnamese koi (17.38±0.05 cm) was observed in T 1 and followed by T 2 (17.00±0.04 cm) and T 3 (16.33±0.03 cm). Similarly, the average highest final length gain of Magur (21.30±0.09 cm) was observed in T 1 and followed by T 2 (17.00±0.05 cm) and T 3 (15.87±0.02 cm) respectively. The survival rate of the stocking Vietnamese koi and Magur were recorded 95.14 and 72.00 % in T 1 ; 93.25 and 64.00% in T 2 ; 90.80 and 68.00 % in T 3 respectively. Fish production in T 1 , T 2 and T 3 were 48.93; 52.79 and 60.83 kg/decimal/120 days, respectively. The total production of T 3 was increased with the increasing of stocking density compare to T 2 and T1. The benefit-cost ratio (BCR) was higher in T 3 where BCR was 1.67 and on the other two treatments BCR was 1.53 in T 2 and 1.52 in T 1 although the highest production was obtained in T 3 but individually growth performance of Vietnamese koi and Magur were higher in T 1. Based on the result of the present experiment, farmers could be suggested to rear Vietnamese koi with Magur at the stocking density of 550 fish/decimal (500 Vietnamese koi and 50 Magur) which was the highest density tried to get more production and financial benefit. Further experiment need to be conducted by taking higher density than the 550 fish/decimal for the optimization of stocking density to get more production and benefit.
Analysis of technical and financial efficiency of intensive white leg shrimp ...AI Publications
The objective of this investigation was to evaluate the technical and financial effectiveness of the current intensive culture of white leg shrimp (Litopenaeus vannamei) in Tien Giang province, Vietnam. A survey was conducted from December 2021 to April 2022 to collect data from shrimp farms in the Go Cong Tay district, which is a planned area of this province for brackish shrimp farming. The results showed that, in terms of technique, most farmers have a lot of experience and a high level of application of science and technology. The average size of the culture pond (0.26 ha pond–1), stocking density (78.83 ind. m–2), survival rate (85.28%), FCR (0.26), and harvested shrimp size (58 ind. kg–1) were similar to other Mekong Delta provinces. There were significant differences in the incomplete water sedimentation and treatment ponds and the major use of groundwater for shrimp farming. In terms of finance, the mean yield was 12,345.97 kg ha–1 crop–1 and was higher than other provinces in the Mekong Delta. However, the mean profit and the total profitability were 17,575 USD ha–1 crop–1 and 0.38, respectively, which was lower than the previous year in the Tien Giang province because of the high input costs. The results of this study show the necessary requirements for the sustainable development of the model of intensive shrimp farming in Tien Giang Province, including (1) the complete rebuilding of the system of farming, water sedimentation, and treatment ponds; (2) the efficient solution for using the surface water; and (3) the support of local authorities, aiming to help farmers reduce input costs and increase profits.

Growth and production of near threatened Ompok pabda (Hamilton) were examined at different feeding frequencies in the present study. The experiment was conducted for four months in three earthen ponds from 1 st April to 31 st July 2018 at Tanore Upazila in Rajshahi district, Bangladesh. The experiment was performed using pabda, (Ompok pabda) fingerling (average) to study the effect of feeding frequency on growth performance. The study carried out considering three treatments, namely T 1 , T 2, and T 3 ; while the feeding frequency was two times per day in treatment T 1 , three times per day in treatment T 2, and four times per day in treatment T 3. Fish were fed considering three-stage of life span; these were fingerling stage, early growing stage, and growing stage. In the fry stage, the fishes were fed 20% feed, in the fingerlings stage the fish were fed 10% feed and in the growing stage, the fish were fed 8% feed of the body weight. The mean water temperature ranged between 27.13±2.10 and 27.29±2.16 °C among treatments, while water transparency ranged between 31.91±1.58 and 29.96±1.84 cm. pH ranged between 7.62±0.14 and 7.70±0.19; while the mean dissolved oxygen was ranged between 5.35±0.11 and 5.56±0.14 among treatments. The final weight gain was found to be highest (56.36±0.01) in the treatment T 2 and lowest (38.23±0.01) in the treatment T 3. The SGR value was higher (3.94±0.01) in the treatments T 2 followed by treatments T 1 and T 3. Net weight gain was significantly (p<0.05) higher in feeding frequency three (56.36±0.1), followed by feeding frequency four (38.23±0.1) and feeding frequency two (40.67±0.73). The FCR value ranged between 1.90 and 2.87 among treatments. The growth performance and specific growth rate were significantly (p<0.05) higher in feeding frequency three. The highest (4049.1±0.1 kg/ha/120 days) production was observed in T 2. Best cost benefit ratio was gained in treatment T 2 .

The study was conducted to evaluate the present status of the production of traditional fermented fish product-shidal (Chapa shutki or shidol) in Lalpur, Ashuganj Union, Brahmanbaria district and its ecological implication and value chain during June to November, 2016. Shidal is produced by natural fermentation process of fresh water punti and marine phaisha and poa fish during winter (October to January). It was found that the Shidal production from freshwater fish in Lalpur has been shrinking gradually due to a decline in fish production from the Meghna River Basin and low supply of raw fishes from others areas. The fishers noted the local extinction of large numbers of once common fish with a gradually low supply of punti and a declining average size among the fishes that are still captured. It was found that not only the total volume of catch decreased but there have been a marked decline in catch per unit effort (CPUF) over the last ten years. During the fermentation season, every day 2-4 ton of raw punti are sold in Lalpur Fish Landing Center and the price of punti varies with grade, season and quality. On an average 4 kg of fresh punti produces 1.2 kg of dry punti and 1.2 kg of dry punti produces 1.44 kg of shidal. It was observed that there were two types of punti used for making shidal in Lalpur-with scales and without scales. The prices of shidal were Tk 800/kg, Tk 500/kg, and Tk 500/kg produced from punti, poa and phaisha, respectively. There are nearly 250 dangaries (fish processing place) for Shidal production and each of the danagaries produce 100-150 motkas (each motka contains 36-40 kg of shidal) of shidal in a season. One motka is sold in Tk. 20,000-24,000 when there is no salt used but Tk. 16,000 per motka when salt is used. It was found that around 2000 people were employed in Shidal production and another 200 people worked in filling in the motka in Lalpur. No chemical are used to make Shidal but some salt is applied during Shidal processing. It was observed that there was no fixed marketing channel for Shidalshutki. Seventy percent (70%) of the Shidal are produced for the domestic market. Shidal produced from small sized punti are exported to India but Shidal produced from marine fishes has never been exported. Although people prefer Shidal made from punti, but due to its gradual disappearance from the natural water bodies, they are forced to consume Shidal prepared from marine poa or phaisa.
Impact of shrimp cultivation on agriculture: A study in Parulia union of Satk...Agriculture Journal IJOEAR
Abstract— Transformation of land use pattern from agriculture to massive shrimp cultivation has been taking place in the coastal areas of Bangladesh. The present study attempts to find out various impacts associated with shrimp cultivation in Parulia union of Debhata upazila, Satkhira. A three months long field study was carried out in 2014 in twelve villages of the unions under study. The data were collected through a combination of qualitative and quantitative approaches: questionnaire surveys, focus groups discussions (FGD), field observation, key informants interview (KII) and secondary materials. The research revealed that shrimp cultivation has direct impact on agriculture in the study location. Though the traditional occupation of people in the area was agriculture (98%, N=102), however, after introduction of commercial shrimp cultivation (approximately 20 to 25 years ago) people in the area are overwhelmingly engaged in shrimp cultivation (86%, N=72). Due to encroachment of agricultural land by shrimp farm present land use strategies in the studied area have also changed drastically. Presently only 42.2 percent of respondents own agriculture land (N=102) whereas about 91.2 percent of respondents (N=102) own gher in the study area. Average agriculture land of respondent households in the area has also been reduced from 3.37 bigha to 1.45 bigha, whilst area and number of ghers of respondent households are increasing. Out of 44.16 km2 of land in the study area 32.66 km2 are under shrimp/bagda cultivation and only 4.19 km2 (Boro cultivation = 3.50 km2 and other crop cultivation = 0.69 km2, Table 8) are now being used for agriculture. With the increase of shrimp cultivation soil salinity is also increasing, as a result most the agriculture land becomes infertile and ultimately crop yields become reduced. Local rice varieties such as Patnai; Durgavogh; Kartikshail; Nagirshail; Chinikanai; Lalgati; Dhungati; Ashfali; Balam; Boran; Jamaibabu etc. are not able to cope with the excessive soil salinity, as a result farmers have to cultivate salinity tolerant high yielding varieties such as Jamaibabu 10; Aftab 1-10; BIRI 28, 30, 41, 47; BINA 7, 8, 10, 22, 28; Minikat; ACI 1, 2; Hira; Akhter 6; Sakti; Sathi; Aloron; Aata 70 etc.

The present study was conducted to assess the livelihood status of fish fry and fingerling traders and socioeconomic condition in the greater Jessore, Bangladesh from April 2013 to September 2013. Data were collected through the use of well-structured questionnaire from the selected area. 73% of traders have single family but only 27% have joint family. 45% fish fry and fingerling traders family has four members. 20% family has five members, 14% family has six members, 12% family has three members 9%family has seven to eight members respectively. 92% traders has own bank account but only 7% traders uses their bank account when they trade fry and fingerling. 87% traders have secondary business like rickshaw business, fruit business, cloth business, fish trading etc. Among 300 fish fry and fingerling traders the sanitation facilities are present 100%. It was found that 69% and 31% of fish farmers used semi-pucca and pucca toilet respectively. Among 300 fish fry and fingerling traders 78% of traders have own house but only 22% of trader live in rental house or place. 46% of traders have institutional education that range from primary to higher education and other 54% of traders have no experience in education. In case of illness 58% of traders and trader's family goes to government hospital, 24% uses private clinic, 15% traders are uses local village doctor and another 3% does not get any treatment or not require no treatment. 93% traders have television, 5% house consist radio and another 2% house no instrument for entertainment. Only 10% trader wants their son and grandson engages with this fish fry and fingerling trading profession. The average monthly income of traders in the peak season is 18000 taka and off-peak season the income is less than 7000 taka per month.

In order to understand the present status of hatcheries, questionnaire interview and participatory rural appraisal tools were used in North-west Fisheries Extension Project (NFEP), Parbatipur during the period from July to December 2015. There are two hatcheries in NFEP, Parbatipur- a carp hatchery and a prawn hatchery. The production of spawn was around 611 kg in the year 2015. According to the target hatchery manager collected brood fish from rivers and other sources which he maintained in their brood stock ponds with proper management. The hatchery manager maintained proper age and weight of broods for spawning and followed the guideline of hatchery operation so that the quality of spawn and fry were good. It was found that the hatcheries produced fish seed of a variety of species such as Indian major carps, carpio, sarpunti, silver carp, grass carp, magur, shing as well as freshwater prawn. The hatchery production activities took place starting from February and continued up to September. The quantity of fish seed produce varied from 25 to 75 kg per hatching cycle depending on size and facilities of hatcheries. The price of fry in NFEP was being fixed by the hatchery manager. However, the price variation was seen due to seasonal variation, species and demand. The average price of fish seed was highest in monsoon and lowest in winter. A number of middlemen were involved in the fry marketing channel of NFEP at Parbatipur. They were responsible for increasing the price of fry at each stage of marketing channel.

Socio-Economic and Environmental Implication’s of Shrimp Cultivation in Andhr...Ruby Med Plus
Impromptu and random expansion of shrimp cultivation is happening in coastal regions of Andhra Pradesh. The exploration of its adverse effects has not received significant attention from the Indian researcher community yet. The shrimp industry is polluting and degrading soils,
water, mangroves, and forests. The sustainable productivity of ecosystems, biodiversity and public health is endangering year after year. Shrimp aquaculture is changing customary patterns of natural resource use by appropriating these resources for its own purposes while restricting rights of local users as coastal Andhra big and experienced farmers in the aqua field are making huge investments in the sector and purchasing the agriculture fields of small farmers to convert it into aqua ponds. This in turn affects livelihoods more widely by disrupting earlier systems of production, distribution and social relations.
In order to elicit the concomitant socio-economic impacts and propose environmental sustainable solutions of shrimp cultivation based on secondary data, the present study was conducted by applying ‘Systematic Review and Content Analysis’ as a research method. The study findings manifest that the constant and unregulated shrimp farming has immense impacts on human health, ecology, environment and sustainability other than economic benefits to aqua farm
owners. The extensive shrimp farming in coastal areas of Andhra Pradesh has negatively expedited the infringement of mangroves, intrusion of salinity, degradation of land, destabilization of coastal ecosystems. The main socio-economic effects challenge the patterns of
livelihood pattern, displacement of family and social structure, internal migration, reduction in grazing field and livestock, changes in the cropping calendar and its pattern and bio-diversity.
The Government of Andhra Pradesh and the financial institutions sponsoring shrimp cultivation has overlooked the impact of shrimp farming on Ecological and sustainability of farm fields and
control of salinity and degradation of mangrooves. In conclusion, appropriate adoption and implementation of the resilient strategies can reduce the adverse effects on the coastal environment, and improve the impact of unplanned shrimp cultivation in Andhra Pradesh and
other parts of India.

Unlocking the mysteries of reproduction: Exploring fecundity and gonadosomati...AbdullaAlAsif1
The pygmy halfbeak Dermogenys colletei, is known for its viviparous nature, this presents an intriguing case of relatively low fecundity, raising questions about potential compensatory reproductive strategies employed by this species. Our study delves into the examination of fecundity and the Gonadosomatic Index (GSI) in the Pygmy Halfbeak, D. colletei (Meisner, 2001), an intriguing viviparous fish indigenous to Sarawak, Borneo. We hypothesize that the Pygmy halfbeak, D. colletei, may exhibit unique reproductive adaptations to offset its low fecundity, thus enhancing its survival and fitness. To address this, we conducted a comprehensive study utilizing 28 mature female specimens of D. colletei, carefully measuring fecundity and GSI to shed light on the reproductive adaptations of this species. Our findings reveal that D. colletei indeed exhibits low fecundity, with a mean of 16.76 ± 2.01, and a mean GSI of 12.83 ± 1.27, providing crucial insights into the reproductive mechanisms at play in this species. These results underscore the existence of unique reproductive strategies in D. colletei, enabling its adaptation and persistence in Borneo's diverse aquatic ecosystems, and call for further ecological research to elucidate these mechanisms. This study lends to a better understanding of viviparous fish in Borneo and contributes to the broader field of aquatic ecology, enhancing our knowledge of species adaptations to unique ecological challenges.

Successful hybridization between Clarias microstomus♂ and Clarias gariepinus♀AbdullaAlAsif1
Hybridization is a significant approach to breeding that enables the creation of new varieties that enhance genetic diversity. Through fish inter-species hybridization, it is possible to produce hybrids that can be utilized in aquaculture and stocking programs to enhance growth rate, transfer desirable traits between species, and combine the favourable attributes of two parents into a single progeny. The present study revealed the successful hybridization between Clarias microstomus (Ng, 2001) ♂ and Clarias gariepinus (Burchell, 1822) ♀ for the first time in the aquaculture industry. C. microstomus is a species of Clariid catfish endemic to the island of Borneo and C. gariepinus is an introduced species widely aquacultured throughout the southeast Asian region. The embryonic development of the hybrid offspring is described with the hatching percentage of 58.63% and the early survival rate for the first 72 hours for the larvae of 85.76%. The hybrids showed no signs of deformities and developed normally. The findings of the study provide a new high yield variety of catfish for farmers and aquaculture industry for increasing production and profit margin.

The objectives of this study are to identify freshwater gastropod species, diversity, and distribution along Sungai Penebak, Sungai Nanga Tiga, and Sungai Kabo in the Betong division. The study was conducted on 10 November 2020. A 50 m transect was laid on the riverbank of all three stations. The existing specimens were counted and collected from each sampling point and stored were taken to the laboratory for species identification. The diversity index and morphological study of freshwater gastropods were performed. Five species of freshwater gastropods belonging to four families were discovered. The five species of freshwater gastropods consisted of Sulcospira pageli, which shows great abundance, followed by Clea nigricans, Brotia costula, Pila ampullacea, and Vittina pennata. The diversity indices of collected Gastropoda species from the different stations, for instance, Shannon Weiner diversity index (H’), Pielou’s evenness index (J’), and Margalef’s richness index were assessed; where station 3 showed higher diversity of Gastropoda compared to other two stations. The information presented in this paper might be helpful for ecological wealth studies and considered as the baseline data for the stream ecosystem in Sarawak, Malaysia.
Macrofaunal diversity on the surface sediment of mangrove habitat adjacent to...AbdullaAlAsif1
Macrofaunal diversity and composition are essential to understanding the ecosystem structures and functions of mangroves in any dynamic estuarine coast. To understand the temporal distribution of macrofaunal community structures and diversity on the surface sediment in the intertidal mangrove forest next to the seagrass beds, this study was conducted at Punang-Sari-River estuary, Lawas, Sarawak (Malaysian Borneo), South China Sea. Sampling was done during post-monsoon, intermediate-September, premonsoon, and monsoon from July 2019 to February 2020. The mean macrofauna abundance was higher pre-monsoon, while Gastropoda Optediceros breviculum (L. Pfeiffer, 1855) was the most abundant (RA = 0.704). Important species index (ISI = 70.36) and percentage of contribution (64.97%) were also higher of this species than any other records from the site. The ANOSIM (Analysis of Similarity), Jaccard index and SIMPER (Similarity Percentage Analysis) analysis suggested that the highest species abundance similarity was observed between pre-monsoon and monsoon, while the highest dissimilarity was observed between intermediate-September and pre-monsoon (74.67%). Seasonal PCA, nMDS, and cluster analysis revealed that pre-monsoon and monsoon were comparable in species and individual abundance. The dominance (0.85) was found significantly higher (P < 0.0001) in intermediate-September, while Simpson (0.734), Shannon (1.56) and Evenness indices (0.528) were found higher in monsoon, followed by the higher Margalef richness indices (3.21) in post-monsoon. It was observed that the seasonal ecological parameters were found to be significantly (P<0.05) different, including the temperature, salinity, rainfall, pore water nitrogenous compounds (NO2, NO3 and NH3-N), phosphorus compound (PO4) and micro minerals. The Canonical Correspondence Analysis (CCA) results suggested that ecological factors influenced several species. Considering the few studies on mangrove macrofauna in Malaysian Borneo, further research on their trophic structures and food web interactions is very important to disclose their overall characteristics and ecosystem functions.

Gonad of sea urchin is considered as food delicacy in many parts of the world due to high nutrition and mineral contents. Several species of sea urchins are available in Malaysia and reported from different habitat, including seagrass beds, coastal breakwater, coral reefs and other ecologically important habitats. The current study was undertaken to evaluate the proximate and mineral composition of long spined sea urchin (Diadema setosum) roe collected from breakwater of Terengganu, Malaysia in October 2019, November 2019 and January 2020. The samples were analysed for proximate including protein, lipid, moisture, and ash content of sea urchin roe. The macro, micro minerals and heavy metals were also evaluated including Ca, Fe, Zn, Cu, Co, Se, Mg, Ni, Pb, Al, and Cd. The result suggested that, long spined sea urchin (Diadema setosum) roe can be considered as good sources of food due to high percentage of protein (ranged between 36.21±0.44 and 50.14±4.63). The presence of heavy metal such as Ni, Pb, and Cd suggesting the breakwater environments were not good enough and the possible sources of heavy metals contamination in sea water environment must be stopped and eradicated. This study provides important information with regard to the proximate and mineral values of D. setosum, as well as the need for a better management of its habitat before D. setosum can be widely promoted as delicacy in this region.
Trends in seagrass research and conservation in Malaysian watersAbdullaAlAsif1
The seagrass ecosystems found in the marine and coastal areas, with substantial economic and ecological services and span all over the globe excluding the Antarctic region. The Coral Triangle and Southeast Asia are recognized as a worldwide hotspot of seagrass species and habitats, encompassing 10-21 species of seagrass in every nation , although the study, understanding, and quantity of publications on seagrass ecosystems are rather limited in the region, including Malaysia. Malaysia contains 18 seagrass species from three families, which occupy 16.8 km 2 of coastal area, where the study and discovery of seagrass species and meadows began in 1904 with the report of Beccari. All of the published papers reviewed reported on Malaysian seagrass-related research, which was divided into nine topic groups: biology and distribution, carbon sequestration, fauna, remote sensing, impact and pollution genetic study, restoration , microbiological investigation, and others. The extensive study of the seagrass ecosystem began in 1993, and we have identified 183 published papers from Scopus, 141 publications from Web of Science, and 42 from Google Scholar. However, the average trend of the number of publications from 1993 to 1999 was 0.71 ± 0.36, while from 2000 to 2022 was 7.70 ± 1.16 followed by the average trend of the yearly number of publications was 6.78 ± 1.08. The highest number of publications was found on faunal categories (43.17%), followed by biology and distribution (21.85%). The number of articles that were published on Malaysian seagrass meadows each year has been discovered to be rising, which indicates that the trends in seagrass study and publishing were progressively garnering the attention of researchers, academics, and the government. However, to better understand the sustainable ecology and ecosystem services provided by seagrass habitats, an emphasis on certain research niches, such as the genetic study of flora and fauna in seagrass meadows, microbial ecology, and restoration as well as conservation of seagrass species might be helpful.

Ylistrum balloti is one of the Pectinidae species distributed within the Indo-Pacific region. Recently, 15 live specimens of Y. balloti were recorded from the continental shelf of Sarawak, Malaysia. The main morphological characteristics were displayed on the outer valve, these being a brown-red colour and a clear concentric pattern of thin brown lines. The prominent internal ribbing numbers on both valves also helped species identification. The preliminary report of Y. balloti revealed that the species is present in Sarawak waters and can be further explored in the future.
Culture and production of Lucilia sericata Meigen (1826) larvae for rearing s...AbdullaAlAsif1
The fly larvae (Lucilia sericata) are being used as an alternative protein source in any kind of animal feed as it reduces the cost of preparation of feed. This current study focused on the physico-chemical and proximate properties of raw poultry waste, while this study also revealed the production process of fly larvae and the proximate composition of it. The poultry waste was collected from Suvro poultry farm, Sutiakhali, Mymensingh, then the physic-chemical properties of the raw poultry waste were determined using different procedures. Three treatments were considered for production of fly larvae, T 1 (3 kg), T 2 (6 kg) and T 3 (9 kg) in a 15 kg capacity tray with three replications. After production, the proximate composition were also measured of fly larvae. Physico-chemical properties such as, color, odor, texture, temperature, pH, total solids (TSS+TDS), chemical oxygen demand, dissolved oxygen, alkalinity, available N, available P, and fiber in raw poultry waste were determined and presented. Proximate composition such as, moisture, total N, total P, available N, total Ca, ash and crude fiber were found in significant amount in the poultry waste. It was found that T 3 (1350±68g) produced highest volume of live maggot compared to the other treatments, but T 2 (17.50±1.10%) produced highest percentage volume. The proximate compositions of fly larvae were assessed and found 56.60±0.25% protein value in it, suggesting that fly larvae could be the protein replacer in fish feed. The result of this study revealed cheap protein source in aquaculture production, such as production and rearing of stinging catfish Heteropneustes fossilis, and the findings might be helpful for cost reduction in aquaculture operation.

Reduction of aquaculture operations and production cost is key to the success and profitability of this enterprise, while protein needs, especially the cost of fish meal, are cery expensive. The current study was conducted to investigate the post-larval production performance of Heteropneustes fossilis using Lucilia sericata maggot as a fish meal replacer in two ways, namely, live larvae and powder form. A 28 days growth trial was performed where five isonitrogenous diets for Heteropneustes fossilis post-larvae were experimented using live maggots and maggot meal, respectively. The proximate composition of each formulated diet, growth parameters of fish post-larvae, such as, weight gain, specific growth rate, protein efficiency ratio, apparent protein utilization, survival rate and the food conversion ratio were examined. After the experiment, the carcass composition of the experimental fishes were evaluated. The best final weight (1.61 g), weight gain (1.418 g), percentage of weight gain (739±1.18%), specific growth rate (2.63), protein efficiency ratio (2.29), apparent protein utilization (85%), survival rate (90%) and lower food conversion ratio (2.06) were observed in fish fed with 75% maggot meal as a substitute of fish meal. This study will help the aquaculture industry, especially the catfish culture in identifying an alternate source of protein and lowering the cost of aquaculture operation.

Molecular study is important to detect variations and similarities among species from the same genus, in case if they do not encompass any morphological or physiological differences. The study was conducted to differentiate among species of Meretrix spp. (Meretrix lyrata, M. meretrix, and M. lusoria) obtained from two locations in Malaysia through the phylogenetic tree. The adductor muscle tissues were used to extract DNA and to perform other procedures; the samples were subjected to analyses using PCR and gel electrophoresis. The multiple sequence comparison was conducted by MUSCLE and the phylogenetic relationships were established using Maximum Likelihood (ML) statistical methods with MEGA 6.0 statistical software. M. lyrata samples showed 99% similarity to the three accessions sequence, where M. lyrata indicated 87% similarities, and M. meretrix showed not more than 89% similarities from the deposited sequence. The nucleotide base composition sequences consisted of the mean of Thiamine (T) 37.9%, Cytosine (C) 15.4%, Adenine (A) 27.4%, and Guanine (G) 19.4%. Maximum Likelihood (ML) analysis was conducted using the Tamura 3-parameter model to establish five major clades on Meretrix spp. and two out-groups clades significantly different from the Meretrix spp. These major clades were closely related to each other at the 50% evidence of bootstrap, which grouped as genus Meretrix. The present study on Meretrix spp. from the Sarawak locality was able to differentiate COI sequences between M. lyrata, M. meretrix, and M. lusoria. M. lusoria was close related to M. meretrix with strong bootstrap supporting evidence at 96% scoring. Moreover, M. lyrata was inferred as the ancestor to M. meretrix, and M. lusoria from Sarawak, Malaysia.
Disappearance or overlooked or untouched? - A brief history of aquatic gastro...AbdullaAlAsif1
The aquatic gastropods (marine and freshwater) in Malaysian Borneo (MYB) have an ancient history of 255 years, while the first record was observed in 1767 by the pioneer Carl Linnaeus. Over time, many European, native taxonomists and conservationists have worked on the diverse group of gastropods in the Malaysian part of Borneo (states of Sabah and Sarawak). No previous work has been conducted to assess the historical status of this particular class of Mollusca. The study objective was to reveal the types of aquatic gastropods and the number of published research and expeditions conducted in MYB. The bibliometric analysis found 145 research publications mentioning the names of the region and reporting at least one gastropod species from this geographic region. Over the history of 255 years, a total of 559 gastropod species were reported by different research groups. Between 1767 and 1900, a total of 150 gastropod species were reported, followed by 79 species from 1900 to 2000 and 330 species from 2001 to 2022. The Grubbs test (p<0.05) identified outlier years for the reporting of gastropod species from MYB with 54 new species each in 2011 and 2020 and 39 species in 2001. Over the history of aquatic gastropod research in MYB, the taxonomists making the greatest contribution were Han Raven and his colleagues from Naturalis who reported 111 new species from the region, followed by Nur Leena Wong from Universiti Putra Malaysia (54 new species). The results suggested that reporting of new species from MYB is increasing, which may reflect the many unexplored sites and suggests the existence of as yet unrecorded species in this ecoregion. In this regard further expeditions and research should improve estimates of the true number of aquatic gastropod species in this area. These results can help the regional governments in making a regional biodiversity database as well as in taking decisions regarding aquatic gastropod research and management.
A ray of hope in the darkness: What we have learned from Yangtze giant soft-s...AbdullaAlAsif1
The Swinhoe's softshell turtle, Rafetus swinhoei (Gray, 1873),) is one of the world's largest freshwater turtles, and possibly the most endangered turtle species on the planet (Stanford et al., 2018). It has an overall length of over 100 cm and a width of up to 70 cm, and it can easily weigh up to 70–100 kg, maximum weight was recorded at 169 kg (Solimine, 2013; Trong, 2018). Despite its enormous size and unusual look, this species is incredibly secretive and only comes to the surface to breathe, preferring to remain submerged deep down. For this species, there is very little ecological information, and the remaining distribution is unclear. This could explain why it's so difficult to positively identify and confirm occurrences of this species in the wild (Trong, 2018). If we look back to the history and biogeography of this species, it can be found that the existential records were documented in the historical literature of the Chinese and Vietnamese dynasties. This species was once thought to only live along the Red River in China and Vietnam, as well as the lower Yangtze River floodplain in China, but its current population size is estimated to be just one wild individual of undetermined sex and a solitary captivity male in Suzhou Zoo, China. Although recent thorough searches in Yunnan, China, and Vietnam failed to confirm the presence of more wild specimens, some sightings were reported until around a decade ago (Stanford et al., 2018), giving hope that more individuals may yet exist in Vietnam.
Snapper shrimp is a symbiotic organism usually hidden under the rocks, sponges and pen shells in the seagrass and coral habitats. The relationship study within snapper shrimp and pen shell was conducted from Merambong shoal, one of the biggest seagrass beds in peninsular Malaysia. A total of 40 individual pen shells were collected randomly and four species of pen shells were identified. 40 Anchistus custoides were found inhabiting symbiotically in the mantle cavity of the pen shell as solitary males and females and heterosexual pairs. Pen shell, Pinna bicolour and Atrina vexillum recorded the highest average SH 217.79±53.15 mm, SV 2.62±1.36 dm3 and SH 164.10-224.78 mm with the SV 1.18±0.43 dm3, respectively compared to the other species. The size of Anchistus custoides ranged from 15.00 to 20.00 mm in length and it was determined to be female due to the presence of eggs in the pleopods. The length of the cephalothorax and its length were highly related (rs=0.563, p≤0.01, N=40) and found wider in females. A little difference in size between the left and right chela in males of identical length was noticed, although the left chela is much bigger than the right. The significant relationship (rs=0.450, p≤0.01, N=40) between the pen shell length and shrimp (male-female) length revealed that the size of the shell is important to be hosted the snapper shrimp in the shell cavity.
Diversity of fisheries in Sarawak, Northwest Borneo: Present status and conse...AbdullaAlAsif1
Information on fisheries resources in East Malaysia is scarce and poorly known. The current review aims to compile a checklist of fisheries resources in the Northwest Borneo (Sarawak, Malaysia) from available published literature, address the resources' present status, and suggest future monitoring needs for selected critical species. The study also aims to determine several Sarawak land-use issues that are in flux and responsible for habitat degradation. Five hundred sixty-four species belonging to 123 families and 32 orders were recorded from Sarawak waters. Freshwater fish species comprised 48.0% of the total, followed by a marine (36.6%), marine-euryhaline (12.9%), and brackish water (2.5%) species. Of this, Cyprinidae was the most dominant group accounting for the greatest number of species (82 species), followed by Balitoridae (34 species), Bagridae (21 species) and Penaeidae (21 species). Therefore, available fisheries resources should be managed carefully as 48 species (9.0%) are currently vulnerable to extinction. Furthermore, the presence of 20 alien species in Sarawak water bodies also requires attention from the authorities due to the potential disruption of aquatic ecological balance. Changing land use issues in Sarawak such as forest degradation, agricultural expansion, peatland deforestation and conversion, logging, destruction of mangrove forests, and construction of hydroelectric power dams and flood mitigation channels pose significant challenges to fishery management in Sarawak. Our study documents the priority of fishery monitoring and conservation in Sarawak water bodies to ensure sustainable management of fisheries resources.
Availability and potentiality of small indigenous species of fish throughout ...AbdullaAlAsif1
This study was conducted with aiming to know the present status of small indigenous fish species (SIS) in Oxbow Lakes/baors and rivers as well as the availability of SIS of fish and their potentiality in the study area. Regular data were collected from some important fish landing center cum markets, Oxbow Lakes and rivers of the study area. The availability of small indigenous species (SIS) of fish declined to a great extent over the years and many of them are rare or endangered due to death of rivers and baors were brought under aquaculture. Besides these, Many of SIS of fish were being increasingly used as trash fish for fish feed purpose. As an over populated country, demand of SIS of fish is increasing day by day. After 1990s almost all Oxbow Lakes have been gradually trying to bring under aquaculture through local community or Department of Fisheries. The most significant message of this study is that, some vulnerable and endangered SIS of fish are locally abundant both in fish landing center, baors and rivers. So they must be conserved for their bioavailability and nutrition throughout the country that would be most intelligent efforts in favor of global ichthyo-biodiversity conservation.

Marketing of fish and fishery products in Dinajpur and livelihoods of the fish retailers were studied during the period from January to May, 2013. A total of 60 fish retailers were interviewed for obtaining pertinent data. A survey questionnaire was developed, pre-tested and finally used for collection of data. The collected data were tabulated using conventional statistical tools. The result showed that the livelihoods of a large number of people are associated with fish and fishery products distribution and marketing in six different markets. Three types of marketing channel were found to be operated in the selected markets. The shorter marketing chain which included the fish farmers, retailers and consumers was found to be more beneficial to the fish producers. Fish traders in village markets generally operate a capital of around TK. 8,000-10,000 and traders in town markets a capital of around TK. 10,000-20,000 per day. It was found that most of the fish traders used their own money. Price of fish depends on market structure, species, and freshness, supply demand of fish and size of fishes. There are seasonal variation in prices with the highest in summer (March to May), and lowest in pre-winter: (September to November) during the fish harvesting season. Different types of dried and salted fish were sold in the markets. Traders have broadly improved their food consumption facilities, standard of living, and purchasing power as an economic sector. However, the unhygienic conditions of the marketplace, lack of ice facilities, poor infrastructure, inadequate storage and poor transportation facilities were reported to be the major constraints hindering the marketing system in the surveyed areas. It is therefore necessary to provision of governmental, institutional and banking assistance for improvement of the marketing system.
Attitude of the farmers towards climate change effect on agricultureAbdullaAlAsif1
Global climate change has triggered the increased incidence of extreme disasters like cyclone, flood, soil salinity, etc. in the coastal region of Bangladesh. In the recent past, an amplified number of fatalities happened and the greater impact also acted upon the attitude of coastal people. Badarpur Union under Patuakhali Sadar upazila of Patuakhali District was the selected locale of the concerned study. Data for this research work were personally collected from a randomly sampled 121 farmers from different villages of Badarpur union by using an interview schedule. Attitude of the farmers was ascertained through a five-point-Likert type scale. Coefficient of correlation (r) was computed to explore the relationships between farmers " attitude and their selected characteristics. The findings revealed that 51.2 percent of the farmers had moderately favourable attitude towards climate change effect while 42.1 percent had slightly favourable and 6.6 percent had highly favourable attitude. The correlation test showed that the education, farming experience, farm size, annual income, training received and agricultural knowledge had positive significant relationships with farmers " attitude towards climate change effect on agriculture while the rest of the characteristics had no relationship in the present study. The focus findings of the present study were that, the attitude of the farmers is changing due to changes in the climatic conditions and there was a positive effect of it on agriculture.

EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...Sérgio Sacani
Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,

The use of Nauplii and metanauplii artemia in aquaculture (brine shrimp).pptxMAGOTI ERNEST
Although Artemia has been known to man for centuries, its use as a food for the culture of larval organisms apparently began only in the 1930s, when several investigators found that it made an excellent food for newly hatched fish larvae (Litvinenko et al., 2023). As aquaculture developed in the 1960s and ‘70s, the use of Artemia also became more widespread, due both to its convenience and to its nutritional value for larval organisms (Arenas-Pardo et al., 2024). The fact that Artemia dormant cysts can be stored for long periods in cans, and then used as an off-the-shelf food requiring only 24 h of incubation makes them the most convenient, least labor-intensive, live food available for aquaculture (Sorgeloos & Roubach, 2021). The nutritional value of Artemia, especially for marine organisms, is not constant, but varies both geographically and temporally. During the last decade, however, both the causes of Artemia nutritional variability and methods to improve poorquality Artemia have been identified (Loufi et al., 2024).
Brine shrimp (Artemia spp.) are used in marine aquaculture worldwide. Annually, more than 2,000 metric tons of dry cysts are used for cultivation of fish, crustacean, and shellfish larva. Brine shrimp are important to aquaculture because newly hatched brine shrimp nauplii (larvae) provide a food source for many fish fry (Mozanzadeh et al., 2021). Culture and harvesting of brine shrimp eggs represents another aspect of the aquaculture industry. Nauplii and metanauplii of Artemia, commonly known as brine shrimp, play a crucial role in aquaculture due to their nutritional value and suitability as live feed for many aquatic species, particularly in larval stages (Sorgeloos & Roubach, 2021).
Immersive Learning That Works: Research Grounding and Paths ForwardLeonel Morgado
We will metaverse into the essence of immersive learning, into its three dimensions and conceptual models. This approach encompasses elements from teaching methodologies to social involvement, through organizational concerns and technologies. Challenging the perception of learning as knowledge transfer, we introduce a 'Uses, Practices & Strategies' model operationalized by the 'Immersive Learning Brain' and ‘Immersion Cube’ frameworks. This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.

Describing and Interpreting an Immersive Learning Case with the Immersion Cub...Leonel Morgado
Current descriptions of immersive learning cases are often difficult or impossible to compare. This is due to a myriad of different options on what details to include, which aspects are relevant, and on the descriptive approaches employed. Also, these aspects often combine very specific details with more general guidelines or indicate intents and rationales without clarifying their implementation. In this paper we provide a method to describe immersive learning cases that is structured to enable comparisons, yet flexible enough to allow researchers and practitioners to decide which aspects to include. This method leverages a taxonomy that classifies educational aspects at three levels (uses, practices, and strategies) and then utilizes two frameworks, the Immersive Learning Brain and the Immersion Cube, to enable a structured description and interpretation of immersive learning cases. The method is then demonstrated on a published immersive learning case on training for wind turbine maintenance using virtual reality. Applying the method results in a structured artifact, the Immersive Learning Case Sheet, that tags the case with its proximal uses, practices, and strategies, and refines the free text case description to ensure that matching details are included. This contribution is thus a case description method in support of future comparative research of immersive learning cases. We then discuss how the resulting description and interpretation can be leveraged to change immersion learning cases, by enriching them (considering low-effort changes or additions) or innovating (exploring more challenging avenues of transformation). The method holds significant promise to support better-grounded research in immersive learning.
The ability to recreate computational results with minimal effort and actionable metrics provides a solid foundation for scientific research and software development. When people can replicate an analysis at the touch of a button using open-source software, open data, and methods to assess and compare proposals, it significantly eases verification of results, engagement with a diverse range of contributors, and progress. However, we have yet to fully achieve this; there are still many sociotechnical frictions.
Inspired by David Donoho's vision, this talk aims to revisit the three crucial pillars of frictionless reproducibility (data sharing, code sharing, and competitive challenges) with the perspective of deep software variability.
Our observation is that multiple layers — hardware, operating systems, third-party libraries, software versions, input data, compile-time options, and parameters — are subject to variability that exacerbates frictions but is also essential for achieving robust, generalizable results and fostering innovation. I will first review the literature, providing evidence of how the complex variability interactions across these layers affect qualitative and quantitative software properties, thereby complicating the reproduction and replication of scientific studies in various fields.
I will then present some software engineering and AI techniques that can support the strategic exploration of variability spaces. These include the use of abstractions and models (e.g., feature models), sampling strategies (e.g., uniform, random), cost-effective measurements (e.g., incremental build of software configurations), and dimensionality reduction methods (e.g., transfer learning, feature selection, software debloating).
I will finally argue that deep variability is both the problem and solution of frictionless reproducibility, calling the software science community to develop new methods and tools to manage variability and foster reproducibility in software systems.

ESR spectroscopy in liquid food and beverages.pptxPRIYANKA PATEL
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.

Abstract: The present study was conducted to assess the livelihood status of fish farmers and socioeconomic
condition in the Jhikargachha upazila, Jessore, Bangladesh. Data were collected from 50 fish farmers for a
period of six months from June 2016 to November 2016. The study indicated that 38% of the farmers were in
age structure of 50-60 years, 44 farmers (88%) were Muslims and others Hindu (12%). About 82% farmers had
a primary occupation of agriculture and others were involved in business (8%), service (4%) and politics (4%).
It was found that, 66% farmers had joint family and others lived in separated family (34%). Majority (44
farmers) respondents had concrete house and rest of (6 farmers) had semi-concrete house. Almost (44%)
farmers used concrete toilet and rest of farmers used semi-concrete (56%). All the respondents used to drink
tube well water for drinking and other household works. Out of 50 fish farmers, 4% had no education (illiterate),
36% had primary education, 42% secondary level (Up to X), 10% S.S.C., 4% H.S.C. and 4% bachelor level of
education. In the study area, 32% of the farmers had ponds of 34-66 dec, 28% had pond of 15-33 dec, 14% had
ponds of up to 100 dec, 22% had ponds of 101-330 dec and 4% had ponds of 330-above dec. It was found that,
62% farmers had training on fish farming and rest 38% farmers had no training on fish farming. Among 50
farmers 64% farmers were found used to invest their own credit and rest 36% farmers took loan from bank,
NGO, money lender and broker agency. Most of the farmers were interested to stock rui, catla and mrigal and
other species. In the study area, cow dung was used by 50 (100%) of farmers, 47 farmers used urea, 40 farmers
used TSP and 34 farmers used MoP. It was found that, 40% farmers produced fish between 1001 kg – 2000
kg/year and 17 (34%) farmers produced 3001 kg-above/year. The highest income was 3,30,75,000Tk/Year and
the lowest income from a pond was 20000 Tk/Year. In the study area, every farmer had at least one mobile
phone. Almost 96% farmers were used to go MBBS doctor and only 4% to homeopathic treatment.

1. Introduction
As a member of south Asian country, Bangladesh is an agrarian, highly populated developing country and the
nation striving hard for rapid development of its economy. Critics showed that the future economic and social
advancement of the country is highly depends on the agricultural sectors and plays a vital role in the socio-
economic blossoming of rural area, carry out the animal protein demand, creating new employment opportunity,
eradication of poverty and earning foreign exchange for the national economy. About 2.7 million people are
directly employed in this sector and another 17.80 million people indirectly earn their livelihood indirectly
involving activities related to fisheries (DoF, 2015). At present fisheries and aquaculture contributes 3.69% to
2. Asian J. Med. Biol. Res. 2017, 3 (4) 463
national GDP and 2.01% to foreign exchange earnings through export (Export Promotion Bureau, 2014).
Fisheries sectors contributed to agricultural GDP as 23.12% (Bangladesh Economic Review, 2015). In fish
production was 3,68,4894 MT in 2014-15 fiscal years. Fish also contributed about 60% to the nation’s animal
protein intake during 2013-14. At present annual fish intake by an individual is 19.34 kg and the annual fish
demand is 3.09 million metric tons (DoF, 2015). So malnutrition problem can be reduced by increasing the
production of fish. Fisheries sector creates 1.4 million full time employments and nearly 11 million part time
employments (Haque et al, 1991). A large portion of rural family members are engaged in part time fishing
from the beels (Hughes et al., 1994). It creates diverse livelihood opportunities for a number of people, many of
whom living below the poverty level, in the form farmers, operators, employees, traders, intermediaries, day
laborers and transporters (Ahmed and Rahman 2005). Pond fish farming has been proved to be a profitable
business than rice cultivation. So many farmers in rural areas are converting their rice field into aquaculture
pond (Islam et al., 2002). Many pond fish farmers in rural areas have taken fish farming activities as their
secondary occupation and most of the people involved in fish farming improved their socioeconomic condition
through pond fish farming activities (Ara, 2005). Bangladesh has got a large number of ponds scattered all over
in the country. There are 47, 08,193 ha water bodies of which 3, 77,968 ha ponds are suitable for fish culture
(BBS, 2014 and DoF, 2015). It has been estimated that about 1.28 million people are directly related to fishing
activities (Mahfuj et al., 2012). For sustainable rural development and poverty elimination, different approaches
have been adopted and the “Sustainable Livelihood Approach” has been gradually expanded with its own core
and principles for poverty focused development activities (DFID, 1998). A sustainable livelihood approach is a
way of thinking about the objectives, scope and priorities for development. Considering the financial hardship
and other complexities of the rural fish farmers, it is important to analyze their livelihood status. In near present
years further improvement in pond aquaculture has gained due to application of technique by introducing
scientific strategies of pond preparation (liming, repair dam), species selection, stocking density, feed
application, fertilizers, water exchange and proper management. This scientific knowledge is gain by the fish
farmer in upazila fisheries office and local NGOs. In the recent year fish farming activities are gradually
increase in Jhikargachha upazila. Most of the farmer followed two types of culture technique are characterized
by extensive (traditional) and improved traditional (semi-intensive) system. The present study was planned to
know the status of fish culture in ponds of the study area. Therefore, the present study was done with the
objectives to investigate the fish culture strategy and management in some selected area of Jhikargachha upazila
under Jessore district and to know the socio-economic condition of involved fish farmer.
2. Materials and Methods
2.1. Study area and periods
The study was conducted in some selected areas of Jhikargachha upazila during June to November, 2016 by
using survey and frequent interview method. Fifty fishermen of the area were interviewed during the survey.
The study was carried out in the five unions named Navaran, Nirbashkhola, Hazaribagh, Shankarpur and Bankra
(Figure 1).

area BKash, Dutch-Bangla Bank, MCash, OK cash and other mobile banking were too much popular for any
amount of transaction.
3.21. Mobile phone used by farmers
In the study area, it was found that every farmer had at least one mobile phone. Some farmer had more than one.
They usually consulted with feed dealers, fertilizer dealers, NGO workers, technical service providers along
with government official through mobile phone.
3.22. Health status of farmers and their family
It was found that 48(96%) farmers were used to go MBBS doctor or allopathic treatment and only 2 (4%)
farmers were used to go to homeopathic treatment (Figure 14).
Figure 14. Health treatment status of farmers.
3.23. Problems faced by the fish farmers
A number of constraints and risks were reported by the farmers. Every farmer responds these problems. These
problems are diseases; lack of proper management; theft; lack of quality fish fry; cheating of fry traders and
multiple ownerships of ponds.
4. Discussion
The present study observed that, the highest number of fish farmer’s age were 50 to 60 year (38%) and lowest
age (30%) were 30-40 years. Khatun et al. (2013) reported that the age group of 36-50 years was the highest
(46%) and 51-65 years were the lowest (26%) considering all fish farmers. This result is more or less relevant to
the present study. Rana (1996) found in his study in Sirajgonj district that 70% of pond farmers were in 18-45
years. Ali et al. (2009) found that most of the fish farmers (50%) belonged to age group of 31 to 40 years in
Mymensingh district. The more or less relevant study were conducted by Islam et al. (2017); Rahman et al.
(2017); Hossain et al. (2015); Asif et al. (2015); Islam et al. (2014); Hossain et al. (2016); Sharif et al. (2015);
Islam et al. (2015); Ali et al. (2016); Rahaman et al. (2015); Sharif et al. (2016) and Ahsan et al. (2016). Present
study observed that, 44 (88%) farmers were Muslims and 6 (12%) farmers were Hindu in the present study.
Khatun et al. (2013) mentioned, 82% of fish farmers were Muslims and 18% were Hindus. Islam (2012)
observed that all the fish farmers (100%) were Muslims which has similarity with the present study. Ali et al.
(2008) was found that maximum fish farmers were Muslims (94%) while small proportions (6%) were hindus in
some selected areas of Bagmara upazilla under Rajshahi district. Islam et al. (2015) investigated in Sundarban
region 62% was muslim and 38% was Hindu. The more or less relevant study was conducted by Islam et al.
(2017); Zaman et al. (2017); Hossain et al. (2015); Asif et al. (2015); Islam et al. (2014); Hossain et al. (2016);
Sharif et al. (2015); Ali et al. (2016); Rahaman et al. (2015); Sharif et al. (2016) and Ahsan et al. (2016).
Present study observed that aquaculture was not the primary occupation of most of the fish farmers. Only 82%
involved in agriculture, rest of farmers were involved with business (8%), service (4%), politics (4%) and rest of
(2%) farmers involved with daily labor work. These studies are more or less similar with the study of Ahmed
(2003); Biswas (2003); Islam et al. (2014); Islam et al. (2017); Hossain et al. (2015); Asif et al. (2015); Islam et
al. (2014); Hossain et al. (2016); Sharif et al. (2015); Islam et al. (2015); Ali et al. (2016); Rahaman et al.
(2015); Sharif et al. (2016); Zaman et al. (2017); Ahsan et al. (2016) and Sen and Roy (2015). In the study of
10. Asian J. Med. Biol. Res. 2017, 3 (4) 471
Jhikargachha, Jessore it was found that 66% fish farmers lived in joint families and 34% lived in separated
families. Provakar et al. (2013) found that about 54% of farmers lived in joint families and 46% in nuclear
(seperated) families in Shahrasti upazila of Chandpur district. This result is not relevant to the present study. Ali
et al. (2008) was found that about 28% farmers lived with joint families and 72% lived with nuclear families.
Sharif et al. (2015); Ahsan et al. (2016) and Asif et al. (2015) stated the similar result with the present findings.
It was found that around 13 (26%) families had four members in their family, 9 (18%) families had five
members in their family, 16 (32%) families had six members in their family and 12 (24%) families had seven
and more members. Hossain et al. (2015) found that 27% family had only 2-4 members. The highest 60%
family has only 5-7 members. Halder (2002) recorded the largest family size (6.67 persons) was in Cast net
fishermen and smallest family size (4.50 persons) was in hogra fishermen of Doba Beel. Most of the fish farmer
(45%) belonged in 4 to 5 member’s family in Mymensingh district (Ali et al. 2009). Average members in the
household of the fishermen were found 3.60±1.34 by Islam et al. (2013) which has similarity with present
findings. In present study, majority respondents 44 (88%) had concrete house (concrete wall with concrete roof)
and rest of 6 respondents (12%) had semi-concrete (concrete wall and tin shed roof) house. Hossain et al. (2009)
found that 40.3% of farmers’ had house of earthen condition, 46.7% had semi-concrete and 10% had concrete
house. However, at beel Chandpur, 36.67%, 56.67% and 6.67% farmer had earthen house, semi-concrete and
concrete house respectively. Rahman (2003) reported that 70% of houses were earthen, while 21% were semi-
concrete and only 9% were concrete. Islam et al. (2017); Islam et al. (2014), Asif et al. (2015), Islam et al.
(2015) and Sharif et al. (2015) did the same study. All the study is more or less similar with the present study. It
was found that almost 22 (44%) farmers used concrete (concreted platform) toilet and rest of 28 (56%) farmers
used semi- concrete (Concrete platform with tin shed) toilet. Sharif et al. (2015) found that 5% concrete toilet,
50% has earthen toilet and 45% semi concrete toilet. Asif et al. (2015) investigated in Jessore that about 69%
and 31% of fish farmers used semi-concrete and concrete toilet respectively. All these study are more or less
similar with the present study. All the respondents 50 (100%) farmers used to drink tube well water and other
household work. Hossain et al. (2015) found that 100% fishermen used tube-well water for drinking purpose.
Sharif et al. (2015) described that about 97% fish farmers used tube well and rest 3% of the farmer uses pond
water. This has more or less similarity with the present study. Education has a role in influencing yields through
production decisions. Out of 50 fish farmers, 4% had no education (illiterate), 36% had primary level, 42% had
secondary level (Up to X), 10% had S.S.C. pass level, 4% had H.S.C. level and 4% had bachelor level of
education. Provakar et al. (2013) found in his study in Shahrasti upazila of Chandpur district that about 10% had
no education while 16%, 48%, 16% and 10% had primary, secondary, higher secondary and bachelor level of
education, respectively. 23.3% farmers were illiterate whereas 14.4%, 8.9% and 6.7% were educated up to
primary, secondary and higher secondary or above level, respectively. This study also has similarity with the
findings of Hossain et al. (2009), Islam et al. (2014), Hossain et al. (2015), Asif et al. (2015), Islam et al.
(2015); Zaman et al. (2017) and Sharif et al. (2015). In the present study, 9 (18%) childrens of farmers had
primary education, 33 (66%) had secondary level, 6 (12%) children had in higher secondary level and rest 2
(4%) children of farmers had bachelor level. Hossain et al. (2015) investigated in Rajshahi that 64% of
fishermen were found to send their children to school whereas 36% did not send children for schooling. These
results are similar with the present (Asif et al., 2015 and Islam et al., 2014). Among the 50 farmer most of them
(32%) had the agricultural land (34-66 dec). On the other hand, 28% had (15-33 dec), 14% had up to 100 dec,
22% had (101-330 dec) and 4% had (330-above dec). Provakar et al. (2013) reported that the average pond size
of the area was 0.24 ha (60 dec) in Shahrasti upazila of Chandpur district. This study is not similar to the present
study. Khan (2012) revealed that the average pond size was 0.13 ha in Sreemongal upazila of Maulvibazar
district which is not to similar to the present study. Islam (2011) reported that the average pond size was 0.16 ha
with a range from 0.04 to 0.81 ha in some selected areas of Maulvibazar district. All the studies are more or less
similar with the present study (Asif et al., 2014). It was found that, 62% (31) farmer had training on fish farming
and rest of 38% (19) farmer had no training on fish farming. Sarwer et al. (2016) said that 18% received formal
training from Upazila Fishery Office with the help of Department of Fisheries (DoF). Hossain et al. (2015)
stated that only 20% fishermen had training on one or more than one related matter, 80% have no any training.
These results differ with the findings of Biswas (2003) and Sultana (2001) study. Khatun et al. (2013) reported
that 14% of farmers received training from DoF and 7% of farmers gain fish farming experience from relatives.
It was found that 32 (64%) farmer used to invest their own credit. And rest of 18 (36%) farmers took loan from
bank, NGO, money lender and broker agency. Sarwer et al. (2016) reported that 91% of the farmers used their
own money for fish farming and 6% of the farmers received loan from bank for farming activities. 3% of the
fish farmers received loan from other sources. Sharif et al. (2015) stated that 5% of finance are contributed by
farmers, 73% farmers got finance from bank whereas 22% farmers took finance from local moneylenders. Asif

et al. (2014) and Zaman et al. (2017) did similar research and got the relevant results. About 70% farmers
fertilized ponds after removing of weeds. Along with rui, catla and mrigal the farmer used to stock other species
like bata (43 farmers), silver carp (44 farmers), grass carp (30 farmers), common carp (34 farmers), pangus (25
farmers), mirror carp (39 farmers), tilapia (32 farmers), monosex-tilapia (1 farmer), scale carp (2 farmers),
sarpunti (1 farmer), bighead carp (22 farmers) and tengra (10 farmers) were stocked. Ahmed (2003) observed
that peak period of carp polyculture was from April to December. On the other hand, Tanjina (2011) stated that
there were 17 available fish species under five orders found during the study period in Shinghorkhali beel in
Dinajpur district. Ahmed (2003) also stated that there were about 15 different fish species found to culture in the
farms of Naogaon district. Biswas (2003) stated that there were about 14 different fish species found to culture
in the farms of Mymensingh district. Most of the farmers had small size pond where they used household waste,
rice bran and mustard oil cake to feed fishes. Farmers increased the use of feeds as rice bran, mustard oil cake
along with commercial feed. Provakar et al. (2013) found in Shahrasti upazila of Chandpur district that 95% of
the farmers applied supplementary feed such as rice bran, mustard oil cake and commercially manufactured feed
and rest 5% of farmers depended on the natural food in the pond. Alam (2006) found that 80% of the farmers
applied supplementary feed such as rice bran and mustard oil cake. In the study area, cowdung was used by 50
(100%) farmers. Urea was used by 47 farmers, TSP (Triple super phosphate) was used by 40 farmers and MoP
(Murate of Potash) was used by 34 farmers. Saha et al. (2003) found that only 25% farmers gave fertilizer in the
pond which has no similarity with the present work. Saha (2004) observed that the average dose of inorganic
fertilizer of urea was 387 kg/ha/year and TSP 176 kg/ha/yr. Rahman (1998) found in his study that doses of
organic and inorganic fertilizer were 11,075 kg/ha and 739 kg/ha, respectively. This study is not equivalent with
the present study. Rana (1996) found that farmers used organic fertilizer was 8,122 kg/ha/year and urea was 3l5
kg/ha/year and TSP was 111 kg/ha/yr. Zaman et al. (2017) also found the similar results with the present study.
The highest production was 27000 kg/yr and the lowest production was 650 kg/yr. It was found that, there were
4 (8%) farmers produced 600–1000 kg/yr, 20 (40%) farmers produced 1001-2000 kg/yr, 9 (18%) farmers
produced 2001-3000 kg/yr, and 17 (34%) farmers produced 3001kg - above/yr during the study. This production
is more or less similar with the study of Siddika et al. (2016); Hossain et al. (2014); Akter (2001) and Ali et al.
(2015). The highest income was 33075000 Tk/yr and the lowest income from a pond was 20000 Tk/yr. In the
study area 9 (18%) farmers got their annual income from 20000 to 100000 Tk. Almost 28 (56%) farmers got
their annual income from 100001 to 500000 Tk, some 5 (10%) farmers got their annual income from 500001 Tk
to 1000000 Tk and rest of 8 (16%) farmers got their annual income from 1000001 Tk to above. Provakar et al.
(2013) stated that the highest (34%) fish farmers earned 75,000 to 1,00000Tk per year in Shahrasti upazila of
Chandpur district. Islam (2015) stated that the average fish production of 16.67% respondents were high (3188
kg/ha/yr), 33.33% respondents were medium (2627/kg/ha/yr), 16.67% low (1864 kg/ha/yr) and 33.33% were
very low (1407 kg/ha/yr) which is similar with the present study. It was found that, every farmer in the study
area had at least one bank account. Some farmers had more than one account for saving money and money
transaction. BKash, Dutch-Bangla Bank, MCash, OK cash and other mobile banking was too popular for any
amount of transaction in the study area. Zaman et al. (2017); Asif et al. (2015) and Sharif et al. (2015) did the
same study and their findings are more relevant with the present study. It was found that 100% farmers had one
or more mobile phone. Which is similar with the findings of Asif et al. (2015) and Sharif et al. (2015). It was
found that 48 (96%) farmers were visited MBBS doctor or took allopathic treatment and only 2 (4%) of farmer
were used to go to homeopathic treatment which is relevant with the findings of Zaman et al. (2017); Siddika et
al. (2016); Islam et al. (2014); Sharif et al. (2015); Islam et al. (2015); Hossain et al. (2014) and Ali et al.
(2015).
From the survey, it was found that diseases, theft, shadow of trees, fallen leaves of tree, multiple ownership,
lack of quality feed, lack of quality fish fry, water contamination by human baths and clothes washing, rapid
water decrease in dry season, dike erosion in rainy season, snakes ate fishes in the pond etc were the major
problems of fish production. Ali et al. (2009) and Ali et al. (2015) reported that lack of scientific knowledge,
multiple ownership of ponds, attack of fish disease and non-availability of good quality fish fry were the major
problems in pond fish culture in Bangladesh. Mollah et al. (1990) conducted that the farmers have major
constraints as; 72.50% of farmers reported theft was one of the main problems followed by financial problem
(40%), lack of contact with fisheries officer (37.75%), lack of fish seeds (27.50%) and lack of feeds (23.75%)
which hampered the production in Laxmipur district which has no similarity with the present study. The similar
study on prospects and constrains were conducted by Shabuj et al. (2016); Chowdhury et al. (2015); Sharif et al.
(2015); Yeasmin et al. (2015); Razeim et al. (2017); Rahman et al. (2015); Rahman et al. (2017); Hossain et al.
(2016); Islam et al. (2017); Shabuj et al. (2015); Islam et al. (2015); Islam et al. (2016) and Hossain et al.
(2017).

5. Conclusions
Generally fish farming played a vital role in the uplifting of the life style and socio-economic condition of fish
farmer of Jhikargachha upazila. From the results of present study, it can be concluded that fish culture has broad
socio-economic benefits for the fish farmers. If the farmers are given precious training, economic support on
easy terms and conditions, more profit would be outputted. Thus it can be concluded that fish farming is a
fruitful business that can help the peasant to uplift their livelihood situation as well as economic criteria. This
study also explored some major problems which were faced by the local people after starting the fish culture.
From the survey, it was found that diseases, lack of proper management, theft, multiple ownership and lack of
quality fish fry etc. were the major problems of fish production.
