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.
Adoption of Aquaculture Technologies among Fish Farmers in Oluyole Local Gove...AI Publications
This study examined the level of adoption of aquaculture technology among fish farmers in Oluyole Local Government area of Oyo State, Nigeria. To improve aquaculture practice in Nigeria, a technology package was developed and disseminated to fish farmers in the Local Government. This package included twelve practices that the fish farmers were supposed to adopt. One hundred and ten respondents were randomly selected from the registered fish farmers in the Local Government. Data were collected through use of well structured questionnaire. Descriptive statistics such as percentage and frequency distribution were used while Chi-square and PPMC were used to analysis the hypotheses. The results showed that level of adoption of the technology was low. Less than half of the respondents adopted the technology. After the liming of pond, which was fully adopted by 55.9%, pond outlet and inlet fully adopted by 50.0% and Feed technology fully adopted by 50.0% which were usually not to specification. The farmers found it difficult to adopt the other recommendations, (e.g., Use the chilled holding for preservation fully adopted by 16.6%, hatchery technique fully adopted by 40.4% Water quality test before fully adopted by 40.1%). It was discovered that the farmers did not have adequate funds to maintain their small ponds and to purchase the necessary feed and other necessities for aquaculture technology adoption. To increase the level of adoption of aquaculture technologies in the study area, it is necessary to change farmers’ perception from subsistence to commercial and sustainable farming practice; to assist the farmers with credit facilities and to intensify activities of the extension agents.
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.
Attitude of farmers towards Pangas farming for their livelihood improvementAbdullaAlAsif1
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 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. During the culture operation, farmers usually had some problems such as pond drying, disease outbreak, dike erosion, shade of tree over the ponds, theft, snakes eating the fish etc.

Economics of fish production in paddy fields in BangladeshAbdullaAlAsif1
This study was conducted to assess profitability of fish production in paddy fields in the village of Kunia and Chandora, under Gacha union in Gazipur sadar upazila in Gazipur district. 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.
Contribution of aquaculture on livelihood development of fish farmer at Noakh...AbdullaAlAsif1
The present study was conducted to assess the contribution of aquaculture on livelihood status of fish farmer at Noakhali sadar upazila. This research work was carried out during the period of February 2013 to July 2013. A total of 50 fish farmers were interviewed with a well-structured questionnaire. 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.

The present study focused on existing status and assessment of sustainability of Pangasius (Pangasius hypophthalmus) farming at Jhikargacha upazila in Jessore district. 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.

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.

Aquaculture is an important sector for economic development and rural jobs in many countries. In Indonesia, aquaculture production increased from 994,962 tons in 2000 to 1.4 million tons in 2004. However, the rapid expansion has also raised concerns about environmental sustainability and food safety. Sustainable aquaculture in Indonesia requires improved management of seed quality, growing systems, fish health, environmental impacts, product quality, and marketing to address these issues.
Comparative economic analysis of organic and inorganic wheatsanaullah noonari
The production of wheat crop for the year 2012-13 is estimated to be 24.2 million tons against last year’s
production of 23.4 million tons. The major reasons for this enhanced production were increase in support price
from Rs.1050 to Rs.1200 per 40 Kg which encouraged improved seed usage and fertilizers. There was also better
weather and comparatively more water available from the reservoirs. The target for wheat production for 2013-
14 has been fixed at 25.0 million tons. The fertilizer has raised the expenses of the inorganic farmers, which are
not, used in organic farming. Cash cost in case of organic and inorganic farming is Rs. 23053.00 and 25846.00
respectively. The non-cash cost of organic and inorganic are Rs.19389.65 and 18815.10 respectively. Total cost
is the combination of cash and non-cash costs that is Rs.42442.65 and 44661.00 in organic and inorganic
farming. Gross margin (GM) is obtained by subtracting the cash cost from the gross value of product. GM is
Rs.33142.65 and 36182.00 in organic and inorganic farming system. Net income is obtained by subtracting the
total cost from the gross value of product. It is Rs.13752.35 and Rs.17367.00 in organic and inorganic farming,
respectively showing a difference of Rs.2615.35. The analysis shows that low net income in organic farming
than the inorganic farming is due to the low yield and high labor cost in organic system. Secondly health and
environmental costs are not included in the analysis, because in the study site farmers are unaware of these costs.

Constraints and prospects of fish farming in Lalmonirhat districtAbdullaAlAsif1
The present study was conducted to know the constraints and prospects of fish farming in Lalmonirhat district of Bangladesh. The data were collected from 100 fish farmers through questionnaire interview for a period of four months from July 2014 to October 2014. Most of the ponds were perennial (72%) with an average size of 0.41 ha and a depth of 1.69 m. All the fish farmers practiced mostly carp polyculture system using different aquaculture inputs like fertilizer, feed, seed, and chemicals. They were usually found to collect fish seed from neighboring districts, mainly Bogra and Mymensingh. The main constrains were availability of quality seed, lack of scientific and technical knowledge, lack of manpower, outbreak of fish diseases, lack of credit facilities, high price of various inputs, low fish price, theft of fish and poisoning the pond water. Though there were many constraints, the fish production from aquaculture sector was increasing gradually in the study area. The total fish production from aquaculture in 2014 was projected 10,663 MT, while the fish production in 2010 was only 7600.4 MT in Lalmonirhat district. If the constraints could be solved, fish production in the study area would possibly be increased tremendously.

Socio economic status of fry collectors at Sundarban regionAbdullaAlAsif1
The study was conducted on the livelihood approach of fry collectors at Shyamnagar upazila under Satkhira district. The objective of the study was to assess the present livelihood status, to identify the socio-economic condition and problem associated with the alternative livelihood approach of fry collectors. The survey was conducted on three unions of Shyamnagar upazila adjacent to Sundarban as study area. In the study area average family size was 5 persons per family. The maximum age level was 20-30 years old. Among the fry collectors 66% was male and 34% was female. Among them 62% was Muslim and 38% was Hindu. About 78% of total fry collectors are landless in the study area. Literacy was 31% of them where female literacy was 28% and male literacy was 72% and most of them can sign only. Most of the collectors about 63% lived in mud walled with golpata shed house. About 73% families have two earner and 68% have single family. Peak season of fry collection was March to May. For collecting fry they use push net, set bag net mainly. They collect fry in the early morning and in early evening for about 6-8 hours. Men collect 150-200 pieces of fry per day in peak season and 40-60 pieces of fry by women. Price varies from 800-3500 Tk. per thousand golda fry. Price is higher in the month on March-May. About 52% collectors engaged in fishing during off season as alternative income source. Their preferable alternative income source are sustainable agriculture, fry nursing, poultry farming, planned fish cultivation, cattle and goat rearing etc. The main problem of converting of fry collection to other profession was lack of other training of other works, lack of capital, poor infrastructure.facilities, absence of industrialization, lack of land, government and NGO level work is very limited.
This document summarizes a study comparing the economic performance of hybrid and conventional rice production in Pakistan. It finds that total costs per hectare were higher for hybrid rice (Rs 148,992.23) than conventional rice (Rs 140,661.68), mainly due to higher seed prices and land management costs for hybrid rice. However, hybrid rice yields were significantly higher (196.14 monds/hectare vs 140.14 monds/hectare for conventional rice). As a result, hybrid rice provided higher total revenue, gross margins, and net returns compared to conventional rice varieties. Most farmers had shifted to growing hybrid rice due to its yield advantages and higher profits.
Performance of Hybrid and Conventional Rice Varieties in Sindhsanaullah noonari
The study was design to compare the economic performance of hybrid and conventional rice production, major
objectives of the study were to asses financial gain from hybrid rice comparing with conventional rice and
Taluka Golarchi was selected for the present study where both on hybrid and conventional rice varieties are
grown, primary data on hybrid and conventional rice was collected from the farmers through personal interviews
with the help of specially designed questionnaire. A simple random sampling technique was used to collect the
data. Statistical approaches used to analysis the data. Total costs per hectare of hybrid rice were 148992.23 Rs
per hectare which were more then conventional rice was 140661.68 Rs per hectactare. Major differences in
hybrid rice production cost are related to higher seed prices, slightly higher land management costs. On an
average higher yield (196.14 monds per hectare) was obtained from hybrid rice while conventional rice yield
(140.14 monds per hectare) was less then hybrid rice. There was 16.64 percent increase in hybrid rice yield
comparing with conventional rice which gives additional income to poor farmers, Price gained per mounds was
almost the same in both activities. High profit was observed in hybrid rice and low profit was obtained in
conventional rice. Most of the farmers focused to grow hybrid rice due to high yield.

The Statutory Interpretation of Renewable Energy Based on Syllogism of Britis...AI Publications
The current production for energy consumption generates harmful impacts of carbon dioxide to the environment causing instability to sustainable development goals. The constitutional reforms of British Government serve to be an important means of resolving any encountered incompatibilities to political environment. This study aims to evaluate green economy using developed equation for renewable energy towards political polarization of corporate governance. The Kano Model Assessment is used to measure the equivalency of 1970 Patents Act to UK Intellectual Property tabulating the criteria for the fulfillment of sustainable development goals in respect to the environment, artificial intelligence, and dynamic dichotomy of administrative agencies and presidential restriction, as statutory interpretation development to renewable energy. The constitutional forms of British government satisfy the sustainable development goals needed to fight climate change, advocate healthy ecosystem, promote leadership of magnates, and delegate responsibilities towards green economy. The presidential partisanship must be observed to delineate parties of concerns and execute the government prescriptions in equivalence to the dichotomous relationship of technology and the environment in fulfilling the rights and privileges of all citizens. Hence, the political elites can execute corporate governance towards sustainable development of renewable energy promoting environmental parks and zero emission target of carbon dioxide discharges. The economic theory developed in statutory interpretation for renewable energy serves as a tool to reduce detrimental impacts of carbon dioxide to the environment, mitigate climate change, and produce artefacts of bioenergy and artificial intelligence promoting sustainable development. It is suggested to explore other vulnerabilities of artificial intelligence to prosper economic success.

Economics of fish production in paddy fields in BangladeshAbdullaAlAsif1
This study was conducted to assess profitability of fish production in paddy fields in the village of Kunia and Chandora, under Gacha union in Gazipur sadar upazila in Gazipur district. 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.

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.

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.

Aquaculture is an important sector for economic development and rural jobs in many countries. In Indonesia, aquaculture production increased from 994,962 tons in 2000 to 1.4 million tons in 2004. However, the rapid expansion has also raised concerns about environmental sustainability and food safety. Sustainable aquaculture in Indonesia requires improved management of seed quality, growing systems, fish health, environmental impacts, product quality, and marketing to address these issues.
Comparative economic analysis of organic and inorganic wheatsanaullah noonari
The production of wheat crop for the year 2012-13 is estimated to be 24.2 million tons against last year’s
production of 23.4 million tons. The major reasons for this enhanced production were increase in support price
from Rs.1050 to Rs.1200 per 40 Kg which encouraged improved seed usage and fertilizers. There was also better
weather and comparatively more water available from the reservoirs. The target for wheat production for 2013-
14 has been fixed at 25.0 million tons. The fertilizer has raised the expenses of the inorganic farmers, which are
not, used in organic farming. Cash cost in case of organic and inorganic farming is Rs. 23053.00 and 25846.00
respectively. The non-cash cost of organic and inorganic are Rs.19389.65 and 18815.10 respectively. Total cost
is the combination of cash and non-cash costs that is Rs.42442.65 and 44661.00 in organic and inorganic
farming. Gross margin (GM) is obtained by subtracting the cash cost from the gross value of product. GM is
Rs.33142.65 and 36182.00 in organic and inorganic farming system. Net income is obtained by subtracting the
total cost from the gross value of product. It is Rs.13752.35 and Rs.17367.00 in organic and inorganic farming,
respectively showing a difference of Rs.2615.35. The analysis shows that low net income in organic farming
than the inorganic farming is due to the low yield and high labor cost in organic system. Secondly health and
environmental costs are not included in the analysis, because in the study site farmers are unaware of these costs.

Constraints and prospects of fish farming in Lalmonirhat districtAbdullaAlAsif1
The present study was conducted to know the constraints and prospects of fish farming in Lalmonirhat district of Bangladesh. The data were collected from 100 fish farmers through questionnaire interview for a period of four months from July 2014 to October 2014. Most of the ponds were perennial (72%) with an average size of 0.41 ha and a depth of 1.69 m. All the fish farmers practiced mostly carp polyculture system using different aquaculture inputs like fertilizer, feed, seed, and chemicals. They were usually found to collect fish seed from neighboring districts, mainly Bogra and Mymensingh. The main constrains were availability of quality seed, lack of scientific and technical knowledge, lack of manpower, outbreak of fish diseases, lack of credit facilities, high price of various inputs, low fish price, theft of fish and poisoning the pond water. Though there were many constraints, the fish production from aquaculture sector was increasing gradually in the study area. The total fish production from aquaculture in 2014 was projected 10,663 MT, while the fish production in 2010 was only 7600.4 MT in Lalmonirhat district. If the constraints could be solved, fish production in the study area would possibly be increased tremendously.

Socio economic status of fry collectors at Sundarban regionAbdullaAlAsif1
The study was conducted on the livelihood approach of fry collectors at Shyamnagar upazila under Satkhira district. The objective of the study was to assess the present livelihood status, to identify the socio-economic condition and problem associated with the alternative livelihood approach of fry collectors. The survey was conducted on three unions of Shyamnagar upazila adjacent to Sundarban as study area. In the study area average family size was 5 persons per family. The maximum age level was 20-30 years old. Among the fry collectors 66% was male and 34% was female. Among them 62% was Muslim and 38% was Hindu. About 78% of total fry collectors are landless in the study area. Literacy was 31% of them where female literacy was 28% and male literacy was 72% and most of them can sign only. Most of the collectors about 63% lived in mud walled with golpata shed house. About 73% families have two earner and 68% have single family. Peak season of fry collection was March to May. For collecting fry they use push net, set bag net mainly. They collect fry in the early morning and in early evening for about 6-8 hours. Men collect 150-200 pieces of fry per day in peak season and 40-60 pieces of fry by women. Price varies from 800-3500 Tk. per thousand golda fry. Price is higher in the month on March-May. About 52% collectors engaged in fishing during off season as alternative income source. Their preferable alternative income source are sustainable agriculture, fry nursing, poultry farming, planned fish cultivation, cattle and goat rearing etc. The main problem of converting of fry collection to other profession was lack of other training of other works, lack of capital, poor infrastructure.facilities, absence of industrialization, lack of land, government and NGO level work is very limited.
This document summarizes a study comparing the economic performance of hybrid and conventional rice production in Pakistan. It finds that total costs per hectare were higher for hybrid rice (Rs 148,992.23) than conventional rice (Rs 140,661.68), mainly due to higher seed prices and land management costs for hybrid rice. However, hybrid rice yields were significantly higher (196.14 monds/hectare vs 140.14 monds/hectare for conventional rice). As a result, hybrid rice provided higher total revenue, gross margins, and net returns compared to conventional rice varieties. Most farmers had shifted to growing hybrid rice due to its yield advantages and higher profits.
Performance of Hybrid and Conventional Rice Varieties in Sindhsanaullah noonari
The study was design to compare the economic performance of hybrid and conventional rice production, major
objectives of the study were to asses financial gain from hybrid rice comparing with conventional rice and
Taluka Golarchi was selected for the present study where both on hybrid and conventional rice varieties are
grown, primary data on hybrid and conventional rice was collected from the farmers through personal interviews
with the help of specially designed questionnaire. A simple random sampling technique was used to collect the
data. Statistical approaches used to analysis the data. Total costs per hectare of hybrid rice were 148992.23 Rs
per hectare which were more then conventional rice was 140661.68 Rs per hectactare. Major differences in
hybrid rice production cost are related to higher seed prices, slightly higher land management costs. On an
average higher yield (196.14 monds per hectare) was obtained from hybrid rice while conventional rice yield
(140.14 monds per hectare) was less then hybrid rice. There was 16.64 percent increase in hybrid rice yield
comparing with conventional rice which gives additional income to poor farmers, Price gained per mounds was
almost the same in both activities. High profit was observed in hybrid rice and low profit was obtained in
conventional rice. Most of the farmers focused to grow hybrid rice due to high yield.

The Statutory Interpretation of Renewable Energy Based on Syllogism of Britis...AI Publications
The current production for energy consumption generates harmful impacts of carbon dioxide to the environment causing instability to sustainable development goals. The constitutional reforms of British Government serve to be an important means of resolving any encountered incompatibilities to political environment. This study aims to evaluate green economy using developed equation for renewable energy towards political polarization of corporate governance. The Kano Model Assessment is used to measure the equivalency of 1970 Patents Act to UK Intellectual Property tabulating the criteria for the fulfillment of sustainable development goals in respect to the environment, artificial intelligence, and dynamic dichotomy of administrative agencies and presidential restriction, as statutory interpretation development to renewable energy. The constitutional forms of British government satisfy the sustainable development goals needed to fight climate change, advocate healthy ecosystem, promote leadership of magnates, and delegate responsibilities towards green economy. The presidential partisanship must be observed to delineate parties of concerns and execute the government prescriptions in equivalence to the dichotomous relationship of technology and the environment in fulfilling the rights and privileges of all citizens. Hence, the political elites can execute corporate governance towards sustainable development of renewable energy promoting environmental parks and zero emission target of carbon dioxide discharges. The economic theory developed in statutory interpretation for renewable energy serves as a tool to reduce detrimental impacts of carbon dioxide to the environment, mitigate climate change, and produce artefacts of bioenergy and artificial intelligence promoting sustainable development. It is suggested to explore other vulnerabilities of artificial intelligence to prosper economic success.

Analysis of Value Chain of Cow Milk: The Case of Itang Special Woreda, Gambel...AI Publications
Ethiopia has a long and rich history of dairy farming, which was mostly carried out by small and marginal farmers who raised cattle, camels, goats, and sheep, among other species, for milk. Finding the Itang Special Woreda cow milk value chain is the study's main goal. In order to gather primary data, 204 smallholder dairy farmer households were randomly selected, and the market concentration ratio was calculated using 20 traders. Descriptive statistics, econometric models, and rank analysis were used to achieve the above specified goals. Out of all the participants in the milk value chain, producers, cafés, hotels, and dairy cooperatives had the largest gross marketing margins, accounting for 100% of the consumer price in channels I and II, 55% in channels III and V, and 25.5% in channels V. The number of children under five, the number of milking cows owned, the amount of money from non-dairy sources, the frequency of extension service contacts, the amount of milk produced each day, and the availability of market information were found to have an impact on smallholders' involvement in the milk market. Numerous obstacles also limited the amount of milk produced and marketed. The poll claims that general health issues, sickness, predators, and a lack of veterinary care are plaguing farmers. In order to address the issue of milk perishability, the researchers recommended the host community and organization to construct an agro milk processor, renovate the dairy cooperative in the study region, and restructure the current conventional marketing to lower the transaction and cost of milk marketing.
Minds and Machines: Impact of Emotional Intelligence on Investment Decisions ...AI Publications
In the evolving landscape of financial decision-making, this study delves into the intricate relationships among Emotional Intelligence (EI), Artificial Intelligence (AI), and Investment Decisions (ID). By scrutinizing the direct influence of human emotional intelligence on investment choices and elucidating the mediating role of AI in this process, our research seeks to unravel the complex interplay between minds and machines. Through empirical analysis, we reveal that EI not only directly impacts ID but also exerts its influence indirectly through AI-mediated pathways. The findings underscore the pivotal role of emotional awareness in investor decision-making, augmented by the technological capabilities of AI. It suggests that most investors are influenced by the identified emotional intelligence when making investment decisions. Furthermore, AI substantially impacts investors' decision-making process when it comes to investing; nevertheless, AI partially mediates the relationship between emotional intelligence and investment decisions. This nuanced understanding provides valuable insights for financial practitioners, policymakers, and researchers, emphasizing the need for holistic strategies that integrate emotional and technological dimensions in navigating the intricacies of modern investment landscapes. As the synergy between human intuition and artificial intelligence becomes increasingly integral to financial decision-making, this study contributes to the ongoing discourse on the symbiotic relationship between minds and machines in investments.0
Bronchopulmonary cancers are common cancers with a poor prognosis. It is the leading cause of death by cancer in Algeria and in the world. Behind this unfavorable prognosis hides numerous disparities according to age, sex, and exposure to risk factors, ranking 4th among incident cancers and developing countries including Algeria, all sexes combined. It ranks 2nd cancers in men and 3rd among women. Whatever the age observed, the incidence of this cancer is higher in men than in women, however the gap is narrowing to the detriment of the latter. The results of scientific research agree to relate trends in incidence and mortality rates to tobacco consumption, including passive smoking. Furthermore, other risk factors are mentioned such as exposure to asbestos in the workplace or to radon for the general population, or even genetic predisposition. However, the weight of these etiological and/or predisposing factors is in no way comparable to that of tobacco in the genesis of lung cancer and the resulting mortality. We provide a literature review in our article on the descriptive and analytical epidemiology of lung cancer.

Haphazard and low soil fertility, low yielding verities and poor agronomic practices are among the major factors constraining onion production in the central rift valley of Ethiopia. Therefore, a field experiment was conducted in East Showa Zone of Adami Tulu Jido Combolcha district in central rift valley areas at ziway from October 2021 to April 2022 to identify appropriate rate of NPSB fertilizer and planting pattern of onion varieties. The experiment was laid out in split plot design of factorial arrangement in three replications. The main effect of NPSB blended fertilizer rates and varieties (red coach and red king) significantly (p<0.01) influenced plant height, leaf length, leaf diameter, leaf number and fresh leaf weight, shoot dry matter per plant, and harvest index. Total dry biomass, bulb diameter, neck diameter, average fresh bulb weight, bulb dry matter, marketable bulb yield, and total bulb yield were significantly (p<0.01) influenced only by the main effect of NPSB blended fertilizer rates. In addition, unmarketable bulb yield was statistically significantly affected (p≥0.05) by the blended fertilizer rates and planting pattern. Moreover, days to 90% maturity of onion was affected by the main factor of NPSB fertilizer rate, variety and planting pattern. The non-fertilized plants in the control treatment were inferior in all parameters except unmarketable bulb yield and harvest index. Significantly higher marketable bulb yield (41 t ha-1) and total bulb yield (41.33 t ha-1) was recorded from 300 kg ha-1 NPSB blended fertilizer rate applied. Double row planting method and hybrid red coach onion variety had also gave higher growth and yields. The study revealed that the highest net benefit of Birr, 878,894 with lest cost of Birr 148,006 by the combinations of 150 kg blended NPSB ha-1 with double row planting method (40cm*20cm*7cm) and red coach variety which can be recommendable for higher marketable bulb yield and economic return of hybrid onion for small scale farmers in the study area. Also, for resource full producers (investors), highest net benefit of Birr 1,205,372 with higher cost (159,628 Birr) by application of 300 kg NPSB ha-1 is recommended as a second option. However, the research should be replicated both in season and areas to more verify the recommendations.

In the current digital landscape, cybercriminals continually evolve their techniques to execute successful attacks on businesses, thus posing a great challenge to information technology (IT) professionals. While traditional cybersecurity approaches like layered defense and reactive security have helped IT professionals cope with traditional threats, they are ineffective in dealing with evolving cyberattacks. This paper focuses on the need for a proactive cybersecurity culture among IT professionals to enable them combat evolving threats. The paper emphasis that building a proactive security approach and culture can help among IT professionals anticipate, identify, and mitigate latent threats prior to them exploiting existing vulnerabilities. This paper also points out that as IT professionals use reactive security when dealing with traditional attacks, they can use it collaboratively with proactive security to effectively protect their networks, data, and systems and avoid heavy costs of dealing with cyberattack’s aftermaths and business recovery.
The Impacts of Viral Hepatitis on Liver Enzymes and BilrubinAI Publications
Viral hepatitis is an infection that causes liver inflammation and damage. Several different viruses cause hepatitis, including hepatitis A, B, C, D, and E. The hepatitis A and E viruses typically cause acute infections. The hepatitis B, C, and D viruses can cause acute and chronic infections. Hepatitis A causes only acute infection and typically gets better without treatment after a few weeks. The hepatitis A virus spreads through contact with an infected person’s stool. Protection by getting the hepatitis A vaccine. Hepatitis E is typically an acute infection that gets better without treatment after several weeks. Some types of hepatitis E virus are spread by drinking water contaminated by an infected person’s stool. Other types are spread by eating undercooked pork or wild game. Hepatitis B can cause acute or chronic infection. Recommendation for screening for hepatitis B in pregnant women or in those with a high chance of being infected. Protection from hepatitis B by getting the hepatitis B vaccine. Hepatitis C can cause acute or chronic infection. Doctors usually recommend one-time screening of all adults ages 18 to 79 for hepatitis C. Early diagnosis and treatment can prevent liver damage. The hepatitis D virus is unusual because it can only infect those who have a hepatitis B virus infection. A coinfection occurs when both hepatitis D and hepatitis B infections at the same time. A superinfection occurs already have chronic hepatitis B and then become infected with hepatitis D.

Determinants of Women Empowerment in Bishoftu Town; Oromia Regional State of ...AI Publications
The purpose of this study was to determine the status of women's empowerment and its determinants using women's asset endowment and decision-making potential as indicators. To determine representative sample size, this study used a two-stage sampling technique, and 122 sample respondents were selected at random. To analyze the data in this study, descriptive statistics and a probit model were used. The average women's empowerment index was 0.41, indicating a relatively lower status of women's empowerment in the study area. According to the study's findings, only 40.9% of women were empowered, while the remaining 59.1% were not. The probit model results show that women's access to the media, women's income, and their husbands' education status have a significant and positive impact on the status of women's empowerment, while the family size of households has a negative impact. As a result, it is important to enhance women's access to the media and income, promote family planning and contraception, and improve men's educational status in order to improve the status of women's empowerment.
The Comparison of Ticket Performance of Existing and Proposed TPRCA SystemAI Publications
This document summarizes a research study that compared the ticket performance of existing and proposed Ticket Performance Root Cause Analysis (TPRCA) systems for IT infrastructure management. The study found that the proposed TPRCA system, which uses domain-driven data mining and incorporates root cause analysis and continuous improvement processes, resulted in higher ticket processing rates and better resolution of issues compared to the existing system. Specifically, the proposed system reduced processing times, classified tickets by issue type to aid resolution, identified root causes of high problem tickets, and implemented solutions to reduce future ticket volumes. A trial implementation in two banking sectors supported these findings.

Monitor indicators of genetic diversity from space using Earth Observation dataSpatial Genetics
Genetic diversity within and among populations is essential for species persistence. While targets and indicators for genetic diversity are captured in the Kunming-Montreal Global Biodiversity Framework, assessing genetic diversity across many species at national and regional scales remains challenging. Parties to the Convention on Biological Diversity (CBD) need accessible tools for reliable and efficient monitoring at relevant scales. Here, we describe how Earth Observation satellites (EO) make essential contributions to enable, accelerate, and improve genetic diversity monitoring and preservation. Specifically, we introduce a workflow integrating EO into existing genetic diversity monitoring strategies and present a set of examples where EO data is or can be integrated to improve assessment, monitoring, and conservation. We describe how available EO data can be integrated in innovative ways to support calculation of the genetic diversity indicators of the GBF monitoring framework and to inform management and monitoring decisions, especially in areas with limited research infrastructure or access. We also describe novel, integrative approaches to improve the indicators that can be implemented with the coming generation of EO data, and new capabilities that will provide unprecedented detail to characterize the changes to Earth’s surface and their implications for biodiversity, on a global scale.

Classification of Clove sizes as planting material to the bulb yield of Garli...Open Access Research Paper
Garlic is one of the highly valued crops in the Philippines. However, low production yield is the main constraint, specifically in the native varieties that could not satisfy the demand. Among the limiting factors are the use of unsuitable clove size as planting materials. The results revealed that clove sizes significantly influenced the growth of garlic. Large clove size and extra-large clove size obtained average plant vigor with ratings of 5.83 and 6.33, respectively. Significant differences were also found in both fresh and dry bulb weights, with the largest clove size yielding the heaviest weights at 19.36g and 16.67g, respectively. Moreover, large and extra-large clove sizes produced the highest number of cloves per bulb with an average of 19.87 and 19.33 respectively. However, no significant differences were observed in yield per plant and yield per hectare. Consequently, large clove sizes employed as planting material increased the vigor, bulb weights, and the number of cloves with no significant effect on the yield. The study showed that planting large clove sizes (2.0-2.50g) is more promising as planting materials of native varieties like Ilocos white.

and a force of economic development in the Tien Giang
province, especially in the eastern districts of this province,
such as Tan Phu Dong, Go Cong Dong, Go Cong Tay, and
Go Cong. However, this production industry is showing
unsustainable development because of a polluted water
environment, serious outbreaks of diseases, and high
production costs (Tien Giang Fisheries Sub-Department,
Vietnam, 2022).
Understanding the characteristics of the current farming
system will facilitate the determination of specific aspects
for potential improvement. This study aims to survey and
evaluate the current situation in order to recommend
effective solutions to contribute to the sustainable
development of the intensive white-leg shrimp farming
industry of Tien Giang province, Vietnam.
II. METHODS
2.1. The Research area and investigated household
choices
This study was performed in the Go Cong Tay district, Tien
Giang province, Vietnam, which is a planned area of the
province for brackish shrimp farming because it is located
outside the saline-prevention dike line. We randomly
selected the 30 households of intensive white leg shrimp-
small scale farming based on the household list of shrimp
farming, which was supplied by the District Department of
Agriculture and Rural Development to collect investigated
information.
2.2. Data collection
Secondary information sources include annual summary
reports of the district’s Agriculture Department and
Provincial Sub-Department of Fisheries. The primary
information was collected from the farmers using a
questionnaire, including (1) general household information
(name, age, gender, education level, labor force, years of
experience); (2) technical aspects (pond area, number of
crops per year, feed, farming time, stocking density,
breeding size, disease management); (3) production
parameters (growth, survival rate, feed conversion ratio);
(4) financial information (cost, revenue, product price,
selling price, profit, profit margin); and (5) farmer’s opinion
regarding advantages and disadvantages of this farming
model. We also deeply interviewed the leaders of the
Department of Agriculture and Rural Development and the
Center of Agricultural Extension and Services in
Agriculture of Tien Giang province regarding the
production situation and related policies for shrimp farming
in the province.
2.3. Data analysis: All the data were statistically analyzed,
using Excel and SAS software.
III. RESULTS AND DISCUSSION
3.1. The General information
Table 1 shows that the average number of people in the
households was 4.93 people, with 1.67 of them working on
shrimp farms (accounting for 33.8% of the total number of
people in the family) and no recruited workers. Due to the
professional nature that requires a lot of health, men were
mainly involved in shrimp farming (accounting for 93.33%
) and women had less important roles in this profession
(6.67%). Most of them had rather low educational levels,
consisting of secondary schools (80% in total) and primary
schools (13.33%), while a low percentage was in upper-
secondary schools (6.67%). These results were similar to
those studies by Quyen et al. (2017), Long and Hien (2015),
and Adesope et al. (2012). The average age of the
household head was 51.40 years old, which included most
of the middle age in the range of 35–55 (66.67%) and the
old age of over 55 (33.33%), especially without a youth age
of under 35. The average number of years of their shrimp
farming experience was rather long, at about 17.07
years. These are also similar characteristics of shrimp
farmers in the Mekong Delta (Phuong et al., 2020; Quyen et
al., 2017; Long and Hien, 2015) and in developing countries
worldwide (Omobolanle, 2008; Adesope et al., 2012; Khan
and Akram, 2012; Rehman et al., 2013; Bozoglu and
Ceyhan, 2007; Okunlola et al., 2011; Kitila and Alemu,
2014).

3.2. Information about the techniques of
shrimp farming:
3.2.1. Pond system and crop
On average, each household had an average area of 0.34 ha,
and a number of ponds of 1.4 ponds were used for intensive
white leg shrimp farming. The average area and depth of
farming ponds were 0.26 ha and 1.59 m, respectively (Table
2), which was smaller than the report of Quyen et al. (2017),
where the average farming pond area was 0.39 ha, and quite
equivalent to the study by Phung and Lam (2019), which
was 0.22 ha. This pond area was suitable for intensive white
leg shrimp culture (Hai et al., 2017). Besides, a tendency to
convert to a smaller farming pond area, about 0.12–0.25 ha,
has been expected by the Mekong Delta farmers because it
is easier to manage and operate. The results also showed that
there was 100% of the shrimp pond edge covered with a
tarpaulin, but completely none of the pond bottom
tarpaulins (Table 2). According to farmers, the current
model does not require using tarpaulin for the bottom
because the cost of tarpaulin is high and incurs several other
costs in care and management. This model is also equivalent
to models without a tarpaulin bottom with a density of
below 100 ind. m–2
in the Mekong Delta (Phung and Lam,
2019).
The results of the present study showed that the proportion
of households with water sedimentation ponds was 66.67%
, with an average area and depth of 0.14 ha and 0.16 m,
respectively. However, no households were equipped with
waste treatment ponds (Table 2), so all the waste from
shrimp farming was discharged directly into the rivers in the
region. This implied an intensive white leg shrimp farming
model in the Tien Giang province on a very small scale, and
the system of sedimentation ponds and treatment ponds was
incomplete compared to the same farming model in other
provinces in the Mekong Delta (Hien et al., 2021; Phuong
et al., 2020; Phung and Lam, 2019; Long and Hien, 2015),
which made it difficult for farmers to manage the
environment and diseases in the farming process. Therefore,
it required local authorities to build a standard water supply
and drainage system for the area. Besides, it would be better
if the shrimp farming households made their plan to use the
common land fund to build a settling pond and for alternate
uses.
White leg shrimp were farmed in Tien Giang province on
average at 2.33 crop year-1
, with two crop year-1
(66.67%)
and three crop year-1
(33.33%) farmed. The farming crops
usually begin in April, October, and November because of
favorable conditions like less rain and high salinity, which
are suitable for shrimp growth. According to the experience
of most farmers and the recommendations of professionals,
the most effective shrimp farming should be two-crop
farming. The remaining time is used to improve the pond
and isolate the disease sources.

%.
3.2.2. Sources of water, seed, and feed
Sources of water and utilization: The water supply used for
shrimp ponds was from drilled wells (100%of households).
Before use, the water was supplied to sedimentation ponds
to settle the suspended matter and was treated using
chemicals for sterilization (66.67% of households).
However, if the household does not have a sedimentation
pond, the well water was directly supplied to the farming
ponds (33.33% of households) (Table 3). Several
households used salt to enhance the salinity of water used
for shrimp farming because well water is usually below 5‰.
One of the major impediments to local shrimp farming was
a lack of clean water. Moreover, the exploitation and use of
groundwater for aquaculture are prohibited by Vietnamese
law. However, the management of these activities is still
strict now. The necessary solutions are: using available
surface water through sedimentation treatment measures;
adhering to seasonality to have a good quality water source;
not discharging wastewater directly into rivers and canals;
strengthening education, and strictly managing the illegal
digging of wells by farmers. The shrimp farming model is
highly effective and stable when it harmonizes technical,
financial, and environmental aspects (Phuong et al., 2020).
Seed sources and seed stocking methods: The quality of
shrimp seed plays a significant role in the success or failure
of the culture. Table 3 shows that farmers only buy directly
from reputable companies without any intermediary agents.
Seeds were guaranteed in sufficient quantity and quality.
The average stocking density was 78.83 ind. m2
; the lowest
was 50 ind. m–2
and the highest was 100 ind. m–2
(Table 7);
this stocking density was equivalent to the model of
intensive shrimp farming without tarpaulin but only half
that of the super-intensive farming model with bottom
tarpaulin in the Mekong Delta (Hien et al., 2021; Phung and
Lam, 2019; Quyen et al., 2017; Long and Hien, 2015).
Interestingly, there are several shrimp seed production
companies that also promote 10 to 40% of the seed quantity.
This is the cause of increasing stocking density and the
actual survival rate. To have a stocking density suitable for
the production model, farmers must calculate the amount of
shrimp seed to buy and the promotion rate. In Tien Giang, a
large percentage of households (86.67%) stocked direct
seeds into farmed ponds without nurseries, and 13.33% of
households where seeds were nursed in biofloc systems
before being stocked into farming ponds (Table 3), which
was called the 2-stage biofloc-farmed model (Phung and
Lam, 2019). This model was reduced to minimize risks in
the early 1–2 farming months of the process, so it was
deemed effective and was recommended for replication (85
% of opinions).
Feed sources and feeding methods: Industrial pellet feed
was used in 100% of the farms and diets according to the
growth stages of shrimp. Feeding machines were also used
in most households (86.67%), and the remaining ones did
not use this equipment because they have small farming
areas (Table 3). Using feeding machines has reduced labor
and improved the feed efficiency for shrimp. All households
set up feeding machines with the same capacity, which
means that the feeding machines have not been used
optimally. As a result, farmers must be instructed on how to
choose the number and capacity of feeding machines for
suitable farming scales for each household.

3.2.3. Equipment and chemicals
The percentage of farming households equipped with the
paddle wheel and the bottom aerator was 100% and 4.66%
, respectively, and in most cases, the number and the set
location of the equipment depend on the farmer's experience
and investment ability. Farmers must be instructed on how
to properly arrange and install equipment in order to manage
the water environment and reduce the cost of use in order to
increase the equipment’s efficiency. According to
Boyd (1990), on average, 4–8 paddle wheels with a capacity
of 2.5 KW, or two air compressors (3 HP) can be installed
for one hectare of ponds. In addition, 86.66% of the
households have been using feeding machines, and the
remaining ones did not use this equipment because they
have small farming areas. The results show that there were
100% of shrimp farming households equipped with backup
generators, water pumps, and water environmental test kits
(Table 4).
All households used chemicals in the pond renovation. The
choice of chemicals used has been mainly based on the
experience and knowledge of farmers. Table 4 shows that
the percentage of households that used unslaked lime and
probiotics was 100, and permanganate potassium and
chlorine were 60% and 20%, respectively. Meanwhile, the
percentage of farmers using chlorine and other chemicals in
other provinces in the Mekong Delta was much higher, at
54.52% and 45.48%, respectively (Phuong and Lam,
2019).

3.2.4. Renovation techniques and management of ponds
Before each farming crop, 100% of households performed
pond renovation using the wet method and coloring pond
water (Table 5), unlike other provinces in the Mekong Delta
that all follow the dry method (Phung and Lam, 2019).
According to Hai et al. (2017), it didn’t matter whether it
was dry or wet as long as the correct technique was
followed. In the survey area, 100% of the households only
supplemented well water without changing the water during
farming crops, periodically fertilized lime, and removed
waste deposited at the bottom. Besides, those who used
probiotics and permanganate potassium were 73.33% and
60%, respectively (Table 4). Most farmers pay attention to
and effectively manage environmental factors such as water
temperature, pH, alkalinity, dissolved oxygen, etc.
However, a huge difficulty is that 100% of farmers did not
change the water (Table 5), resulting in low clarity (20–30
cm), while in the provinces in the Mekong Delta, the
percentage of households that change the water regularly
after two months of farming accounts for 72.50% (Phung
and Lam, 2019).

Disease control: The disease was most visible in the first 30
farming days (53.33% of respondents); after 30-60 farming
days (46.67% of respondents). After 60 days until harvest,
there was no disease in farmed shrimp (Table 6). The
pathogens are very diverse, and the disease frequency was
also very different for farms. The statistical results show
that White Feces Syndrome had the highest rate (51.61%),
followed by Acute Hepatic Necrosis Syndrome/Early
Mortality Syndrome (25.81%), Yellowhead virus (12.90%
), Necrotizing hepatopancreatic bacterium (6.45%), and

3.3. Parameters of harvesting and finance
Table 7 shows that the average survival rate, harvesting
shrimp size, and FCR were 85.28%, 58 ind. kg–1
, and 1.24,
respectively, which were similar to other provinces in the
Mekong Delta, Vietnam. In 2021–2022, the input costs
(seed, feed, drug, chemical, etc.) increased to lead the
product price up to 3.65 USD kg–1
was higher than in
previous years, while the average sales price of 5.05 USD
kg–1
was unchanged. This was the reason for the average
profit of 17,575.40 USD ha–1
crop–1
and the total
profitability of 0.38, which were lower than in previous
years (Phuong et al., 2020; Quyen et al., 2017; Long and
Hien, 2015). Market prices often govern shrimp harvesting
time. Most farmers knew how to choose the right time to
harvest shrimp to reduce the molting shrimp rate. Although
intensive shrimp farming is profitable, its attractiveness has
been very low due to its relatively high-risk level, large
capital requirement, and negative impacts of wastewater
discharge into the environment from farming (Long, 2017).

3.4. Advantages and disadvantages of intensive white leg
shrimp farming in Tien Giang province
When farmers were asked about the sources of scientific and
technical information being used, 100% of the opinions
were from relatives and technical staff of business
establishments, 66.66% from radio and television, and
46.67% from newspapers. However, there weren’t any
sources received from the state extension. The role of the
district Agricultural Service Center in extension is
ineffective these days because of difficulties such as the
separation and union of functions, the lack of staff
specialized in fisheries, and the limited funds for the
extension. Meanwhile, there is a very strong development
of business establishments for food, chemicals, and aquatic
drugs that possess technical staff to support farmers. Several
establishments accompany farmers by supporting food,
drugs, chemical costs, etc., at the beginning but pay after
harvest with a high-interest rate, of about 10% per month. It
is necessary to strengthen local extension and encourage
sustainable association between farmers and agents by
negotiating a reasonable interest rate.
During the shrimp farming period, 100% of farmers said
they were facing many shortcomings in terms of
unfavorable water environments, difficult-to-control

diseases, increasing production costs, an 86.67% lack of
production capital, and 53.33% unpredictable prices. These
are also common challenges in Mekong Delta intensive
white leg shrimp farming (Quyen et al., 2017; Long and
Hien, 2015; Phung and Lam, 2019). It is necessary to
coordinate between sectors in the province and district and
to get the cooperation and consensus of farmers to solve
these problems. These actions are urgent and long-term at
the same time.
Regarding increasing the level of intensive farming soon, up
to 86.66% of farmers reported that it was hard to
successfully implement in the current conditions because
the technique is difficult to apply. Besides, 100% of farmers
believed that the cost was high, resulting in a lack of
investment capital. There were 93.33%of the opinions were
that farmers would keep the current model because the
demand for the world's white leg shrimp market was still
open, and 6.67% thought they would shift the production
scale to super-intensive 2-stage shrimp farming.

IV. CONCLUSIONS AND RECOMMENDATIONS
4.1. Conclusions
The model of intensive white leg shrimp farming in Tien
Giang was small-scale with incomplete sedimentation and
treatment pond systems. Farmers had a lot of experience and
technical knowledge, as well as obstacles to the polluted
water environment, diseases, and increasing production
costs, which were the same as in all other provinces in the
Mekong Delta. The difference was that farmers did not use
surface water to culture shrimp but used illegal well water,
thereby affecting the sustainability of the model. Although
productivity increased, production costs increased rapidly,
and selling prices did not increase, making total profitability
lower than before. This made the attractiveness of the
intensive white leg shrimp farming model very low. Most
farmers did not want to increase investment and expand
production scale.
4.2. Recommendations
There are many issues that need to be addressed for the
sustainable development of white leg shrimp farming in
Tien Giang, including:
Enhancing extension activities: strengthening expertise
knowledge training activities; carrying out demonstration
plots related to technical factors such as the proper
arrangement of water sedimentation and treatment ponds,
addle-wheels, and feeding machines; and rational use of
drugs, chemicals, and biological products in shrimp
farming; guiding farmers in effectively using surface water
and limiting the exploitation of underground water sources;
arranging seed nursery places in shrimp ponds and
determining suitable stocking density for the intensive
farming model without tarpaulin.
The local government should have policies to support loans
with low-interest rates for farmers; effectively manage the
price and quality of input materials; develop policies to
encourage investment in research to create Vietnamese-

branded products with good quality and reasonable prices;
and invest in completing water supply and drainage systems
to meet the requirements of the intensive white leg shrimp
farming areas in the coming years.
