Molluscs are the most important resources among all the seafood items in South-East Asian countries. However, very little information available on nutritional value of molluscs in these regions. In this study, we evaluated the 7 economically important species of molluscs in terms of proximate composition, amino acids profile, fatty acids profile, cholesterol and heavy metal contents in the bivalves (mussels, oysters, clams and cockles) and univalve (snail) collected from freshwater and marine environments of Bangladesh. The results of the proximate analyses revealed that significantly higher amount of crude protein contents were present in marine water oysters, clams and cockles (59.3 AE 0.3 to 75.4 AE 0.2%) than the freshwater mussels and snail (36.9 AE 0.4 to 49.6 AE 0.6%) on dry matter basis. However, carbohydrate contents were significantly higher in freshwater mussels and snail (30.2 AE 0.9 to 57.3 AE 0.2%) compared to the marine water bivalves (8.1 AE 0.4 to 20.2 AE 0.6%). Crude lipid contents were ranged from 2.5 AE 0.2 to 11.2 AE 0.1% and ash from 11.4 AE 0.1 to 16.8 AE 0.6% among the bivalves and snail species. The amino acid contents were comparatively higher in marine water bivalves than their freshwater counterparts. Saturated fatty acid contents were found to be higher in marine water bivalves than the freshwater mollusc species. The results also show that the omega-3 (eicosapentaenoic acid, EPA and docosahexaenoic acid, DHA) fatty acids were comparatively higher in oysters, clams and cockles in marine water than those in freshwater mussels and snail. However, omega-6 fatty acids like linoleic acid (LA), αlinolenic acid (ALA) and arachidonic acid (ARA) were higher in freshwater mussels and snail than in the marine bivalves. The n-3/n-6 ratio were significantly higher in oysters and cockle species than the other groups of bivalves and snail. The index of atherogenicity and index of thrombogenicity of the mollusc species ranged from 0.74 AE 0.1 to 1.74 AE 0.2 and 0.5 AE 0.1 to 2.6 AE 0.2, respectively. The results show that marine water bivalves contained higher amount of potassium, sodium, iron, chlorine especially oyster species contained significantly higher iodine than the freshwater bivalves and snail. However, freshwater mussels and snail showed significantly higher amount of zinc contents than the marine bivalves. The heavy metal contents such as arsenic, chromium and mercury were absent or present in very tiny amounts among the mollusc species. Significantly higher amount of cholesterol was present in marine bivalves and freshwater snail species than the freshwater mussels. Overall, the results indicate that marine bivalves can be good sources of high quality protein and lipid especially EPA and DHA. On the other hand, freshwater mussels and snails also could be good sources of protein, LA and ARA but scarcity of EPA and DHA.

“…Bangladesh is one of the world's leading fish producing countries. The availability of fish fry is an essential prerequisite for fish culture (Moniruzzaman & Mollah, 2010).

“…Bangladesh is facing tremendous problem of fry production and rearing due to the lack of technical knowledge and proper management practices. For improved fish culture, it is therefore imperative to know how feeds are related to growth and survival of fry (Moniruzzaman & Mollah, 2010) in laboratory condition.…”

An experiment was conducted with Labeo bata fry for 60 days to examine the growth performance and survival in response to three supplementary feeds i.e. wheat bran, maize bran and mixed diet. The length gain, percent length gain, weight gain, percent weight gain and specific growth of the fry were found significantly higher (p<0.05) in mixed diet. The highest survival rate (74.38±8.1%) was shown by the mixed diet treated fry which was significantly higher than those of maize bran and wheat bran treated fry respectively. There were no significant differences (p<0.05) among the treatments in term of water temperatures, pH and dissolved oxygen (DO). Thus, on the basis of the fry growth performance and survival rate, it could be suggested that the mixed diet of wheat bran and maize bran is suitable for the culture of L. bata fry.Jahangirnagar University J.

Prawn (Macrobrachium rosenbergii) culture is socially more acceptable, technically and economically viable and sustainable. The freshwater catfishes Heteropneustes fossilis (shing) and Clarias batrachus (magur) adapt well to hypoxic water bodies and high stocking densities as well. So, shing and magur may be a good candidate to culture with prawn in ponds/ghers to save the farmers from losing their investment in case of shrimp mortality and getting additional income from fish. With this view, this study was conducted to evaluate the feasibility of polyculture with three treatments each with three replications. Stocking density of shing was variable i.e., 200nos/decimal in T1, 300nos/decimal in T2 and 400 nos/decimal in T3. On the other hand, stocking density of magur and prawn juveniles was 50 and 30 nos/decimal respectably for all treatments. The experimental ghers were treated with salt (NaCl) (150g/decimal), potasium permanganate (5g/decimal) along with lime (125 kg/ha). After stocking fish were fed using floating nursery feed containing 32%, protein and 7% lipid at the rate of 10-2% for shing and magur nursing, floating oil coated grower feed (27% protein and 6% lipid) at the rate of 6-2% for shing and magur grow out and prawn grower (30% protein and 7% lipid) at the rate of 6-2.5% of estimated fish and prawn biomass. At least 10% of stocked catfish and galda were sampled fortnightly using cast net. Physico-chemical parameters of the experimental ghers water were monitored at weekly. After six months of culture the highest growth performance (47.0 g) and survival (19.94%) for shing obtained from T3. Whereas the average growth of shing was recorded 37.02 and 41.14g; growth of magur 99.21g and 99.51g and growth of galda 69.74 and 70.19 for Treatment T1 and T2 respectively. Except ammonia and iron content the other observed parameters of ghers water found congenial for fish health. The value of Benefit-Cost Ratio (BCR) was 1.4 that seems to be profitable and feasible of this polyculture practice.
