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.

The present study was conducted to know the fish markets and marketing practices in Noakhali district for a period of 5 months; November 2014 to March, 2015. Five types of marketing channels were found in this study and most were similar in nature as marketing places were in same town and not far apart. The average cost by a retailer to trade fish was estimated at Tk. 171.6 /day. This cost included rent of trading spot, ice and local transportation. The average income of retailers in three markets was estimated at Tk. 640/day/retailer. It was found that 21% of fish supplied in the markets were carps (Indian and Exotic), 17.3% marine fish, 15.7% hilsa, 12.7% catfish, 11.3% small fish, 11% Tilapia and pungus, 7% others mix species and 4% prawn. It was reported that availability fish species in three different markets round the year ranged from 55 to 72. However, during the study period, a total of 39 fish species under 24 families were found in three markets. It was found that marine fish comprises average 33% and freshwater fish comprises average 67% in the three markets. The price of fish depends on market structure, species quality, size, weight and season. The price of galda and bagda were varied from 580±10 to 560±8 Tk. /kg, and 370±10 to 350±5 Tk. /kg respectively. The price of catla, tilapia, ilish, Thai pangus and silver carp were varied from 390±10 to 360±8 Tk. /kg, 165±5 to 150±8 Tk. /kg, 900±10 to 860±5 Tk. /kg, 140±10 to 125±5 Tk. /kg, and 160±8 to 155±5 Tk./kg, respectively. In Noakhali, around 50-180 retailers were involved in each market. It was found that the daily supply of fish in Municipal market, Datter hat and Sonapur was about 12-13, 7-8 and 2.5-3ton, respectively. Inadequate infrastructure, transportation, shortage of ice in peak season, hygienic condition and packaging facilities were cited as main constraints. It was found that 80% of the fish retailers have improved their livelihood status through fish trading to a certain degree.
Post-harvest handling and quality loss of Indian major carps in the distribut...AbdullaAlAsif1
Post-harvest loss of mrigal (Cirrhinus cirrhosus), catla (Catla catla), rohu (Labeo rohita) and kalibaush (Labeo calbasu) in different distribution channel of Noakhali district, Bangladesh were observed during the month of January 2015 to April 2015. Sensory evaluation method was adopted in order to gather information about quality loss of fish and existing handling condition at different stakeholder level. The observed fish were fresh at fisherman level but as the day progress along with temperature variation fish started losing quality and most of their quality found lost at retailer level. Fisherman supplied fish to beparies at 5% quality loss, further 10%, 20% and 22% loss was observed through aratder, retailer and consumer respectively. DPs varied with the month basis, compared to January-February the DPs were higher in March-April which indicates that temperature rise cause more quality loss of fish. Most of the fishes crossed DP 3.0 at retailer level because of long term exposure to open air coupled with unhygienic condition of markets. Different sizes baskets were used for transportation of fish with or without icing. Live fishes were transported with water in gallon or drum and they could retain their shelf lifelong time than that of dead fish or fish with no icing condition. The unsold fishes were preserved in refrigerator and re-icing was adopted by 70% retailer. The ice ratio of fish: ice was 1:1 in March-April and 2:1 in January February. The more quality loss of fish the more ice was used. Bad handling practices due to transportation and in markets also caused quality deterioration of some fishes. Usually post-harvest loss of fish is not taken under the consideration which eventually because economic loss coupled with food insecurity but proper steps to reduce loss can compensate the post-harvest fish loss.

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.
Socio-economic status of fish retailers in Jashore sadar, BangladeshAbdullaAlAsif1
The study was conducted to determine the fish retailer's livelihood and socioeconomic status in three markets of Jashore for a period of six months from February to August, 2016. The average net profit of fish retailers was found higher in Boro bazaar (Tk.350) followed by Palbari bazaar (Tk.325), Chuadanga Bus Stand bazaar (TK.275). The average age groups of 20-65 years were found among the markets. The study shows that 53% fish retailers had nuclear family and 47% had joint family. Most of the housing conditions were kacha (69%) and Muslim fish retailers were predominant in all markets. Among the total 45 traders interviewed, 42% were illiterate, 31% have primary level education, 24% have secondary level education and none of them had bachelor level of education. It was found that fish retailers of Boro bazaar and Palbari bazaar sold an average of 35 kg fish daily, compared with Chuadanga Bus Stand bazaar 15 kg per day. The daily supply of fish in Boro bazaar can be estimated at 1.6 MT (25 retailers' × 65 kg) while 0.3 MT (15 retailers × 20 kg) and 0.45 MT (15 retailers × 30 kg) in C.B Bazar and Palbari bazaar respectively. Improvement in basic infrastructure such as, clean water supply, sanitation facilities, adequate drainage and ice facilities are recommended by the present study.

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.

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.
Tilapia (Oreochromis mossambicus) marketing system in greater Jessore region,...AbdullaAlAsif1
The study was carried out to access on the present status of Tilapia (Oreochromis mossambicus) marketing in Jessore sadar in Jessore district. Study period was carried out during June 2013 to December 2013. For the market survey, two important fish markets in Jessore town, namely Boro Bazaar and Rail-station Bazaar Similarly, two important local fish markets in the Jessore Sadar namely Churamonkati Bazaar and Ambot-tola Bazaar were selected to carry out comparative studies of tilapia marketing between town and local markets. A total of 80 traders were interviewed in Local and Town markets, 40 in each area. In the study area 55% of harvested tilapias are sold to the local agents, while the rest (45%) are sold to the suppliers and about 60% of tilapias are transported to the boro bazaar. The rest (40%) of the tilapia, which are under-sized, are transported to nearby local markets. The average farm-gate prices of tilapia varied between Tk 55 and Tk 85 per kg. According to the survey, a wholesaler typically operates with capital of around Tk 11,968 per day, ranging from Tk 8,350 to Tk 27,125 per day. According to the survey, 70% of wholesalers used their own money for fish marketing including tilapia, while the rest (30%) received loans. In the study area tilapia comes from Jhenidah, Satkhira, Jessore then it is supplied to Boro Bazar to wholesaler then it is distributed towards local market. Around 20 to 25 individuals are associated with fish trading including tilapia, except for Boro Bazaar which is larger. The total average marketing costs from producers to consumers was calculated to be Tk 13.02 per kg of tilapia which is sub-divided into: primary market – Tk 3.25 (25%), secondary market – Tk 4.75 (36%), and retail market – Tk 5.02 (39%). In the study area, tilapia prices are generally lower between September and December, rising during the following four to five months. The highest average marketing margin and profit per kilogram of tilapia was found in secondary market, followed by retail and primary market. The proportion of respondents identifying poor road and transport facilities was 24%. Only 20% and 12% of traders identified lack of money for this business. In case of socio economic condition traders 25% has earthen house and 65% has Pucca house and 10% has Semi pucca house. In the study area about 35% traders goes to the MBBS and rest of 65% is goes to the quack or non trained doctor. Traders has earthen toilet of 27%, Pucca toilet is 50% and Semi pucca is 23%. All traders have education at some level, which implies that the reported literacy rate is 83%. Most traders were quite young, with an average age estimated at 36 with a range from 23 to 57. The average family size of tilapia traders was estimated at 5.5 in a single family.
The accessibility of fish in the market relies upon the interest and supply of fish in the market transport and communication facilities and period of catch and culture of fish. A total of 26 fish species such types Indian major carp, catfish, exotic carp etc are available in the market. From the study it was observed that the dominant portion of the market following carp 50%, shrimp & prawn 20%, catfish 8%, Tilapia 10% and other species 12% represented species. Carp fishes were dominant in the studied market because of the market location where carp species are cultured very much. It also observed that Rui, Catla, kalibaus, mrigal, minor carp,common carp,silver carp,grass carp, bighead carp ,pangas, tilapia, bagda and galda were most available in the market because of those species has the highest demand in the market. Fish marketing channel in fish market completely managed, supported, financed and controlled with rules by traditional, diligent and skillful middlemen. The present study it was observed the (faria) carried the fish from fish farmers to the markets by their own or hired transport and sell them to aratdars or the fish farmers carried their catches sell them to aratdars and sell it to wholesalers. Farmer/fishermen also sell directly to the wholesaler. In a very rare case, farmers carry the fishes to the markets and sell them to the retailers or consumer. Several problem of fisherman and consideration sanitation, water supply, hygienic condition, drainage facilities and insufficient ice facilities all over the fish market and there are lack of preservation facilities & shortage of ice supply are in turn affects the quality of fish. The fish farmer’s education background is not satisfactory because five farmers asked them education level to four farmers were up to the eight grade and one person was passed B.Com whose name is Tapas Sarkar.
Fish biodiversity and their present conservation status 5 1-53-491Md. Monjurul Hasan
This study was conducted between January 2016 and December 2016 with a view to assessing the
biodiversity of fishes in the River Meghna and their conservation status both in Bangladesh and global
aspects. A total of 107 fish species belonging to 13 orders and 26 families were documented. Perciformes
was found to be the most dominant order consisting 32% of the total fish population. Cyprinidae was
found to be the richest family (16%). Twenty common groups were recorded in the studied areas.
Estuary-River was found to be the biggest habitat for the maximum number of fishes (43%). Twenty one
threatened fish species (20%) were recorded from the River Meghna in which 11 species (10.28%) were
found as Vulnerable (VU), 8 species (7.48%) as Endangered (EN) and 2 species (2%) as Critically
Endangered (CR). Steps should be taken to conserve threatened fish species of Meghna River from the
risk of extinction.

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.

The purpose of this study was to determine the number of marketing channels and the amount of margin in each marketing channel to determine the efficiency of marketing and the added value received by each marketing actor of Julung-Julung fish in Kinabuhutan Village. The population in this study were fishermen catching julung-julung fish, fish processors, middlemen and retailers. Data was collected using the census method for fishermen and fish processors, while traders used purposive sampling. The data collected in the form of primary data and secondary data. Primary data collection techniques with observation and interviews. The data obtained were analyzed using quantitative descriptive analysis and qualitative descriptive analysis. Quantitative descriptive analysis using marketing margin analysis. Based on the research results, it is known that there are only 2 marketing channels for fresh julung-julung fish in Kinabuhuta Village, namely from fishermen to consumers and from fishermen to fish processors. Both channels have a marketing margin of 0 which means that the channel is efficient because the price paid by consumers is the same as that received by fishermen. The marketing channels for smoked Julung-Julung fish are 4 marketing channels with marketing areas, Kinabuhutan, Likupang, Bitung, Airmadidi, Manado and Tomohon. Based on the results of the margin analysis, it is known that the farther the distance between producers and consumers, the longer the marketing channel and the larger the marketing margin, making it more inefficient. In this study, the marketing channel no. 1 with the marketing area to Tomohon is inefficient because the price paid by the final consumer is the most expensive so that the largest marketing margin is Rp. 12,000,-. While the most efficient which is marketed in the production area is channel 4 because the margin is 0. The added value received by fishermen is Rp. 4,500, -. Per 20 fish, the fish processing producer is Rp. 7,850,-, while the middlemen and retailers vary according to the marketing area. The lowest marketing costs are those that are marketed in the production area in Kinabuhutan, namely 0 and the largest is the farthest, Tomohon.

The present study was conducted in three seasonal beels in Gacha union under Gazipur sadar upazila in Gazipur district during the period from June 2015 to January 2016. The objectives of the study were to evaluate the impact of stocking common carp on the abundance and biodiversity of native fish species in seasonal beels. Three seasonal beels such as Baroholai, Makhna and Buridha which were connected with Turag River through different canals were selected to implement the study. Baroholai and Makhna beel were stocked with common carp fingerlings at 2500 per hectare. Buridha beel served as control. Necessary data were collected from the fishermen and lease holders of the concern beel through using structured questionnaire by survey method. A total of 42-43 species of fishes were recorded from stocked beel as against of 43 species in control beel. Shanon-Weiner diversity index averaged 2.58 in stocked beel as opposed to 2.68 for control beel. The studied beel had medium richness in terms of biodiversity and faunal abundances. Per hectare fish production was 522-577kg in stocked beels as compared to 365kg in control beel. Cyprinidae was the most abundant group contributing to the bulk of fishery yield. Surface feeder took a lead over other groups of fishes in stocked beel as opposed to bottom feeder in case of control beel. Bottom dwelling small catfishes seems to be affected in presence of common carp in the stocked beels. Control beel harboured increased number and quantity of catfishes. Fish productions in the seasonal beels were profitable. Per hectare total cost of fish production averaged tk 34976.67 as against of total gross return of tk 92683.67. Benefit cost ratio (BCR) was found to be 2.57-3.42 in stocked beel and 2.01 in control beel. Further researches are needed to precisely determine the possible consequences of stocking common carp in seasonal beels.

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.

This study was conducted in two major shark landing centers; BFDC fish harbor, Cox’s Bazar and Fishery Ghat
fish landing center, Chittagong from January-December, 2014. Semi-structured interview, case study, frequent visit to
the informants found in and between the trade channels were done for data collection. As there is no forms of gear
size limitation or seasonal restriction in the existing fish act, most landed sharks were found to be smaller in size. Big
sharks were found to be processed and dried in some enclosed building in the form of cottage while smaller sharks
in Nazirertek fish drying area. Dried salted and iced sliced meat of shark and its sun-dried bones are sold to local
consumers for consumption. Dried shark fins, skins, teeth are exported to different countries like Myanmar, India,
Singapore, Thailand, Hong Kong, China and USA. Bangladesh earned 0.09 crore taka by exporting 1 MT shark
fin during 2012-2013. Although no shark products were exported from Bangladesh during 2010-11 to 2011-12 due
to banning of shark catch and trade in several countries, different body parts of shark were smuggled to Myanmar
from Cox’s Bazar illegally. All the activities cause a serious threat to shark biodiversity in the Bay of Bengal. Steps
should be taken to save and conserve shark in our ecosystem through the inclusion of shark in the fish act restricting
indiscriminate killing, establishing shark sanctuary, smuggling of shark and its product and improving the trades of
shark products.
Ideally, the role of data collection is to support the monitoring of stated objectives and support for management processes. States should ensure that timely, complete, and reliable statistics on catch and fishing efforts are collected and maintained in accordance with applicable international standards and practices and in sufficient detail to allow sound statistical analysis. Such data should be updated regularly and verified through an appropriate system.

The present study was conducted in Jhikargacha sub-district of Jessore district with the view to evaluating status of polyculture of Pangasius hypophthalmus with carps from July to December 2012. The mean age and experience of the respondents was 41.28±12.19 and 9.48±3.12 years respectively. Culture pond size was 0.41±0.21 ha (0.343 to 0.478 at 95% CL). 67.50% culture ponds were leased ponds and mean yearly lease value was 535364.70±468224.20 BDT/ha. All the ponds were rectangular in shape and perennial in nature. During preparation of pond, all the ponds were dried by draining out the water. Liming was done at 229.30±118.70 kg/ha (pre-stocking) and 250 kg/ha (post-stocking). Application rate of various fertilizers during post stocking management were recorded as- 155.12±79.10 kg/ha (cow dung); 158.27±79.85 kg/ha (urea); and 79.90±42.93 kg/ha (TSP). Five species of fishes were found to be stocked at the rate of 7377 individuals/ha including 93.10% P. hypophthalmus seeds and 6.90% other carps. Supplementary feeding was done daily and the application rates were 444.23±236.41 kg/ha (rice bran), 228.29±116.96 kg/ha (mustard oil cake), and 912.91±468.05 kg/ha (commercial pangus feeds, pellet). Average fish production was found 6672.84 kg/ha. All the fishes grown in the study area were marketed to fish landing centers and markets of three districts- Chuadanga (47.50%), Dhaka (30%) and Jessore (22.50%). The average cost-benefit ratio was 1:1.15. High mortality, low growth of seeds, and high input price were the major problems.

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 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.
Tilapia (Oreochromis mossambicus) marketing system in greater Jessore region,...AbdullaAlAsif1
The study was carried out to access on the present status of Tilapia (Oreochromis mossambicus) marketing in Jessore sadar in Jessore district. Study period was carried out during June 2013 to December 2013. For the market survey, two important fish markets in Jessore town, namely Boro Bazaar and Rail-station Bazaar Similarly, two important local fish markets in the Jessore Sadar namely Churamonkati Bazaar and Ambot-tola Bazaar were selected to carry out comparative studies of tilapia marketing between town and local markets. A total of 80 traders were interviewed in Local and Town markets, 40 in each area. In the study area 55% of harvested tilapias are sold to the local agents, while the rest (45%) are sold to the suppliers and about 60% of tilapias are transported to the boro bazaar. The rest (40%) of the tilapia, which are under-sized, are transported to nearby local markets. The average farm-gate prices of tilapia varied between Tk 55 and Tk 85 per kg. According to the survey, a wholesaler typically operates with capital of around Tk 11,968 per day, ranging from Tk 8,350 to Tk 27,125 per day. According to the survey, 70% of wholesalers used their own money for fish marketing including tilapia, while the rest (30%) received loans. In the study area tilapia comes from Jhenidah, Satkhira, Jessore then it is supplied to Boro Bazar to wholesaler then it is distributed towards local market. Around 20 to 25 individuals are associated with fish trading including tilapia, except for Boro Bazaar which is larger. The total average marketing costs from producers to consumers was calculated to be Tk 13.02 per kg of tilapia which is sub-divided into: primary market – Tk 3.25 (25%), secondary market – Tk 4.75 (36%), and retail market – Tk 5.02 (39%). In the study area, tilapia prices are generally lower between September and December, rising during the following four to five months. The highest average marketing margin and profit per kilogram of tilapia was found in secondary market, followed by retail and primary market. The proportion of respondents identifying poor road and transport facilities was 24%. Only 20% and 12% of traders identified lack of money for this business. In case of socio economic condition traders 25% has earthen house and 65% has Pucca house and 10% has Semi pucca house. In the study area about 35% traders goes to the MBBS and rest of 65% is goes to the quack or non trained doctor. Traders has earthen toilet of 27%, Pucca toilet is 50% and Semi pucca is 23%. All traders have education at some level, which implies that the reported literacy rate is 83%. Most traders were quite young, with an average age estimated at 36 with a range from 23 to 57. The average family size of tilapia traders was estimated at 5.5 in a single family.
The accessibility of fish in the market relies upon the interest and supply of fish in the market transport and communication facilities and period of catch and culture of fish. A total of 26 fish species such types Indian major carp, catfish, exotic carp etc are available in the market. From the study it was observed that the dominant portion of the market following carp 50%, shrimp & prawn 20%, catfish 8%, Tilapia 10% and other species 12% represented species. Carp fishes were dominant in the studied market because of the market location where carp species are cultured very much. It also observed that Rui, Catla, kalibaus, mrigal, minor carp,common carp,silver carp,grass carp, bighead carp ,pangas, tilapia, bagda and galda were most available in the market because of those species has the highest demand in the market. Fish marketing channel in fish market completely managed, supported, financed and controlled with rules by traditional, diligent and skillful middlemen. The present study it was observed the (faria) carried the fish from fish farmers to the markets by their own or hired transport and sell them to aratdars or the fish farmers carried their catches sell them to aratdars and sell it to wholesalers. Farmer/fishermen also sell directly to the wholesaler. In a very rare case, farmers carry the fishes to the markets and sell them to the retailers or consumer. Several problem of fisherman and consideration sanitation, water supply, hygienic condition, drainage facilities and insufficient ice facilities all over the fish market and there are lack of preservation facilities & shortage of ice supply are in turn affects the quality of fish. The fish farmer’s education background is not satisfactory because five farmers asked them education level to four farmers were up to the eight grade and one person was passed B.Com whose name is Tapas Sarkar.

The present study was conducted in Jhikargacha sub-district of Jessore district with the view to evaluating status of polyculture of Pangasius hypophthalmus with carps from July to December 2012. The mean age and experience of the respondents was 41.28±12.19 and 9.48±3.12 years respectively. Culture pond size was 0.41±0.21 ha (0.343 to 0.478 at 95% CL). 67.50% culture ponds were leased ponds and mean yearly lease value was 535364.70±468224.20 BDT/ha. All the ponds were rectangular in shape and perennial in nature. During preparation of pond, all the ponds were dried by draining out the water. Liming was done at 229.30±118.70 kg/ha (pre-stocking) and 250 kg/ha (post-stocking). Application rate of various fertilizers during post stocking management were recorded as- 155.12±79.10 kg/ha (cow dung); 158.27±79.85 kg/ha (urea); and 79.90±42.93 kg/ha (TSP). Five species of fishes were found to be stocked at the rate of 7377 individuals/ha including 93.10% P. hypophthalmus seeds and 6.90% other carps. Supplementary feeding was done daily and the application rates were 444.23±236.41 kg/ha (rice bran), 228.29±116.96 kg/ha (mustard oil cake), and 912.91±468.05 kg/ha (commercial pangus feeds, pellet). Average fish production was found 6672.84 kg/ha. All the fishes grown in the study area were marketed to fish landing centers and markets of three districts- Chuadanga (47.50%), Dhaka (30%) and Jessore (22.50%). The average cost-benefit ratio was 1:1.15. High mortality, low growth of seeds, and high input price were the major problems.

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.
Freshwater gastropod diversity in the selected lotic environment, Betong, Sar...AbdullaAlAsif1
Freshwater Gastropoda can be considered as the biological indicator in ecosystems such as rivers, streams, lakes, and ponds. 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.
Population characteristics of the Japanese threadfin bream Nemipterus japonic...AbdullaAlAsif1
Nemipterus japonicus (Japanese threadfin bream) is one of the most significant fish species throughout the Indo-Pacific regions. No previous studies on the population dynamics of N. japonicus have been carried out in the Eastern Malaysia (Malaysian Borneo). The present study focused on the population dynamics of N. japonicus from April 2013 to March 2014 in the coastal area of Bintulu, South China Sea. Local fishermen provided samples, which were then analysed. The FiSAT II software was used to evaluate the collected length frequency data. The asymptotic length (L ∞) and growth coefficient (K) were 26.78 cm and 0.85 yr-1, respectively. The growth performance index (ϕ'), total mortality coefficient (Z), natural mortality (M) and fishing mortality (F) were 2.785, 2.97, 1.63 and 1.34 per year, respectively. According to the estimates, the exploitation rate (E) for N. japonicus was 0.45, while the E 0.1 , E 0.5 and E max were determined as 0.72, 0.4 and 0.806, respectively. The obtained value of exploitation was less than E max, although slightly higher than E 0.5. The recruitment characteristics of N. japonicus have been stable throughout the year, with one peak pulse. The results contribute to the knowledge of the dynamics of N. japonicus populations and are important for the sustainable management of the Sarawak fishing resources.

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.

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.

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.

community who lands a catch in excess of his need and seeks
to exchange the fish for another product is implicitly involved
in the activity of fish marketing. According to Shang (1981)
[8]
, the return of farm depends on production level and market
prices, the price usually fluctuating seasonally due to
variations in the supply and demand.
In The primary market the fishermen/farmers sell the catch to
primary fish traders who may be known as a mahajan or
aratder. Primary fish trader may buy through a local agent
(dalal) who typically earns 1-5% commission for his services.
The primary traders sell the fish in a wholesale market to local
retailers (nickaries), local wholesalers (paikers), or distributors
(beparies or chalanies) who transport the fish to other districts.
The sale is normally carried out through the medium of a
commission agent (aratder) who conducts public auctions.
From the secondary market fish is transported at a distance by
the distributors (bepari/chalani) to wholesaler market in
district town. After procuring at the higher secondary markets,
local wholesalers (paikers) sell to consumers through retailers
(nickaries). Communication among the traders in different
markets takes place with mobile phone, telephone, which
keeps wholesale prices in line throughout in the country. The
least informed party is the fishermen, because of their physical
isolation from the markets.
Materials and methods
The study was conducted in six markets in Dinajpur sadar
upazila in Bangladesh. Study period was carried out during
January to May, 2013. It was based on market survey,
obtaining information through a sample survey among fish
traders. The survey method was chosen in the present study
because it was thought to be more advantageous. There are
many fish markets in Dinajpur sadar- among them six markets
(3 town markets and 3 village markets): Bahadur bazaar,
Chalk bazaar, Rail bazaar, Pulhat bazaar, Sikder bazaar,
Khanpur bazaar were selected as study areas. In the selected
areas 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. Data for the
present study were collected for five months from January to
May, 2013. A collection method was divided into 3 steps;
these were 1) Questionnaire interview: For questionnaire
survey, fish traders were selected through simple random
sampling method. Interviews were conducted at the market
centre during marketing time., 2) Focus group discussion with
intermediaries: FGD was conducted with intermediaries in
Dinajpur sadar upazila to get overview of livelihood of fish
traders, fish distribution and marketing systems, constraints of
fish distribution and marketing etc. A total of 9 FGD sessions
(6 in town markets and 3 in village markets) were conducted
where each group size of FGD was 5 to 10 intermediaries. And
3) Crosscheck interviews with key informants: Crosscheck
interviews were conducted with key informants such as school
teachers, local leaders, Upazila Fisheries Officer (UFO) and
relevant NGO workers where information was contradictory or
requested for further assessment. The collected data were
tabulated using conventional statistical tools. Data were
analyzed using MS Excel 2007.

Result
A large number of people are concerned with fish production,
distribution and marketing systems in Dinajpur sadar. The
main aim of this study is to describe the present status of fish
marketing system of fish and fishery products in Dinajpur
sadar. This description is based on secondary data and primary
data collected in six different markets of Dinajpur sadar
upazila.
Marketing system and fish distribution
A marketing system includes all activities involved in the flow
of goods from the points of initial production to the ultimate
consumer. It includes the exchange activities associated with
transferring property rights to commodities, physically
purchasing and allocating resources, handling, products,
disseminating information to participants and institutional
arrangements for facilitating these activities. The market chain
from farmer to consumer passes through a number of
intermediaries, such as: local fish traders (paikers),
wholesalers and retailers.
Fig 2: Fish marketing chain from farmers to consumers in Dinajpur sadar.
Marketing Portion in Primary to consumer market
Normally fish farmers do not directly communicate with
consumers. Market communication was usually being made
through middlemen. Farmers partially sold their fish directly
to the wholesalers (about 15%); the wholesalers sold it to the
retailers. The paikers carried the fish (about 80%) to the
markets by their own or the retailers. In a very rare case,
farmers carried the fishes to the markets and sold them to the
retailers.
Fig 3: Marketing portion
A total of 60 retailers were interviewed for market survey
stated that price of fish depend on market structure, species
and size of fishes. They also noted that price varies according
to freshness, supply and demand of fish. There are seasonal
variation in prices with the highest in summer (March to May),
and lowest in pre-wint: (September to November) during the
fish harvesting season.
Consumers or local traders are not willing to pay high prices
for exotic carps due to less demand or taste of the fish. The
highest average price of Indian major carps was noted for rohu
(Tk. 350). Among the exotic carps the highest price was found
for grass carp. However, the prices of cat fish were so high
because of taste and demand. The price of fish is given in
figure below.

from 7am to 10pm while in Railbazar, Chalk bazaar from 7am
to 6pm and in Khanpur bazaar, Sikder bazaar traders are
engaged in fish trading from 12pm to 8pm. It was found that
almost all traders of six markets spend around 8 to 12 hours in
fish selling if sufficient fishes are available. But some traders
can sell their fish earlier and engage themselves in other
homestead works.
Amount of fish sold
During the survey it was found that fish traders in Bahadur
bazaar sold an average 120 kg daily while in Chalk bazaar 110
kg, in Rail bazaar 90 kg, in Pulhat bazaar 75 kg, in Sikder
bazaar 60 kg and in Khanpur bazaar 40 kg. Amount of fish
sold are given below in figure 5.
Fig 5: Amount of fish sold
Number of Retailers
There are 80-90 retailers involved in Bahadur bazaar, 30-40
retailers in Chalk bazaar, 40-50 retailers in Rail bazaar, 7-10
retailers in Pulhat bazaar, 10-12 retailers in Sikder bazaar, 7-10
retailers in Khanpur bazaar.
Supply of Fish
The daily supply of total fish was 10.2 tons (average 85 traders
x 120kg) in Bahadur bazaar, 3.85 tons in Chalk bazaar
(average 35 traders x 110kg), 4.05 tons in Rail bazaar (average
45 traders x 90kg), 0.6 tons in Pulhat bazaar (average 8 traders
x 75kg), 0.66 tons in Sikder bazaar (average 11 traders x
60kg), and 0.32 tons in Khanpur bazaar (average 8 traders x
40kg) respectively.
Profit of fish retailers
According to the survey, it was found that the average income
of fish retailers in Bahadur bazaar was Tk. 400 per day, Tk.
350 per day in Chalk bazaar, Tk. 350 per day in Rail bazaar,
Tk. 300 per day in Sikder bazaar, Tk. 350 per day in Khanpur
bazaar. The percentage of profit is shown in figure.
Fig 6: The percentage of profit
Income of wholesalers
The wholesalers are influential persons in the fish markets and
they have a strong relationship with other intermediaries.
Wholesalers engage themselves a short period (2 to 3 hours)
for fish selling as middlemen and earn a considerable amount
of money in comparison with retailers. They earned about Tk.
350 to 600 per day, and engaged themselves a long time in
marketing activities.
Price of fishes
In the study area, fish prices were determined by actions at
Arat level. In retail levels prices were determined by open
bargaining between retailers and consumers. Captured carp in
Bangladesh are more expensive than cultured carp. Among the
5.
~ 90 ~
International Journal of Fisheries and Aquatic Studies
cultured species rohu, catla and mrigal fetched higher prices
than exotic carps. The reason for low prices of exotic carps can
be explained by low demand and poor taste but an important
factor is lower production costs to allow supplying fish at this
price. Naturally the price of carp depends on market structure,
species, size and quality. Survey of six markets showed that
the prices per kilogram of carp increased with size for both
Indian major carps (i.e; rohu, catla and mrigal) and exotic
carps (silver carp, grass carp and common carp). All the
traders enjoyed low bargaining power because of the product
perish-ability and need for cash. When the demand for the
products was high and supply was limited, then the price was
high and vice-versa.
Problems in fish marketing
During the survey fish traders stated a number of fish
marketing problems. It included higher transport costs, poor
road communication facilities, inadequate drainage system,
poor supply of ice, poor water supply, unhygienic condition,
poor sanitary facilities, lack of capital, higher demand of
labors, exploited by middlemen, lack of storage facilities, lack
of marketing facilities, lack of market information etc.
According to retailers, political disturbances sometimes affect
fish transport as well as marketing. As a result, perishable
fishes get damage and the traders are to sell these at a cheaper
price; sometimes they even fail to get any return, due to
decomposition of fishes. Fish traders were asked to mention to
top most problems as they fell regarding fish marketing.
Where, 20% of the respondents identified unhygienic market
place 25% poor supply of ice, 15% lack of capital, 15%
exploited by middlemen, 25% mentioned inadequate drainage
system, were the most important problems for fish marketing.
Livelihood status of fish retailers
The aim of this study was to determine the socio-economic
status of retailers. Especially, emphasized was given on such
variable namely age, religion, education, family size, housing
condition, sanitary facilities, health facilities, electricity
facilities, and other socio economic issues.
Age distribution
In the study area the fish retailers were classified into different
age groups such as 15 to 30 years, 31 to 40 years, 41 to 50
years, 51 to above years. Out of total surveyed fish retailers in
Dinajpur sadar maximum were in the age group of 31 to 40
years (33.33%), whereas only 16.67% were found in the group
of above 51 years. Age distribution of traders are given in

Discussion
Fish farming is regarded as industry in many countries of the
world but the fish farmers in our country do not communicate
directly with the consumers. Length and type of fish market
chain from the producers to final consumer varies
significantly. This chain passes through a number of
intermediaries such as local fish traders, beparies, aratder,
wholesalers and retailers. In our present study three types of
marketing channels were found. These channels were (a) Fish
farmer–paikers- wholesalers-retailers-consumers, (b) Fish
farmers- wholesalers –retailers- consumers, and (c) Fish
farmers–retailers- consumer. The present findings are in
agreement with the result of Quddus (1991) [5]
, Rahman (2003)
[6]
, Mia (1996) [3]
who identified several types of marketing
channels in Netrokona, Mymensingh and Gazipur district
respectively, all of which involved active participation of
aratdar and beparies as a strong link in the existing marketing
system. The above observations are in conformity with our
findings.
From our survey it was found that the wholesalers make a
significant amount of profit. Generally they make a profit of
Tk. 350-600 per day. The wholesalers invest more capital than
the retailers, and as such, they have greater control over the
agent and retailers. The present findings are in agreement with
the report of Rahman (2003) [6]
who observed similar scenario
in Gazipur Sadar and Sripur Upazila markets.
The price of fish varies with the types of species, sizes,
freshness, market demands and seasons. Usually the prices of
fishes are higher in April to July when the fish are in short
supply. On the contrary, prices remain lower during November
to January which seemed to be related with the increased
availability of both captured and cultured fishes during this
period (Quddus, 1991) [5]
. It has been found that the price of
Indian major carps always remain higher than the exotic carps.
This difference in the prices of fishes might be related with the
flesh texture and taste of the local fishes. Rahman (2003) [6]
reported that major carps such as rohu, catla and mrigal
fetched higher price than exotic carps in Gazipur district.
Quddus (1991) [5]
concluded that fish price is influenced by
7.
~ 92 ~
International Journal of Fisheries and Aquatic Studies
seasonal abundance, market structure and origin of fishes.
Ranadhir (1995) [7]
reported that rohu was the most expensive
fish followed by catla, mrigal, common carp and grass carp in
the southeast Bangladesh. Our present findings are in
agreement with the above reports.
In our study fish market and marketing environment were
found to be manifested with a large number of constraints.
These are higher transport costs, poor road communication
facilities, inadequate drainage system, poor supply of ice, poor
water supply, unhygienic condition, poor sanitary facilities,
lack of capital, higher demand of labors, exploited by
middlemen, lack of storage facilities, lack of marketing
facilities, lack of market information etc. They also mentioned
that political disturbances may also affect fish transporting as
well as marketing of fish. As a result, the fish get damage and
traders become bound to sell these at a cheap price, and even
they fail to earn any return for decomposition of fish. Rahman
(2003) [6]
described that traders of Gazipur faced the problems
of higher transport cost, exploitation by middlemen, poor ice
supply and lack of money as well as political disturbances. A
very much similar situation was also observed by Dasgupta
(2004) [2]
and Paul (2006) [4]
in Mymensingh and Rajshahi
district.
From the study it was found that Muslim fish traders (68.33%)
were predominant. Siddique (2001) [9]
mentioned that Muslim
fish traders were predominant in the market of Mymensingh.
Rahman (2003) [6]
noted that in Gazipur the highest percentage
of fish traders up to 30 age groups. It is noteworthy that mostly
the fish traders in all level of marketing chain have educations
at some level. Among the total 60 traders interviewed, 20%
were illiterate, 26.67% can sign only, 35% have primary level
education, 18.33% have secondary level education and none of
them had bachelor level of education. Mia (1996) [3]
found that
most of the fish traders had secondary level of education in his
study in Mymensingh town. On the contrary, Dasgupta (2004)
[2]
reported that majority of the fish traders in Fulpur upazila
had primary level of education. The apparent difference in the
education level of the fish traders seems to be related the
locality and proximity to district town. Young people
particularly the Muslims are coming to the fish marketing
business in increased number. Active participation of the
