The nutrient profile of five freshwater fish species viz., Mystus vittatus, Ompok bimaculatus, Channa striata, Wallago attu and Pangasianodon hypophthalmus were studied. The proximate composition data shows that the moisture and fat content differed significantly (P<0.01) among the fish species. The fat content was significantly higher in P. hypophthalmus and M. vittatus. The moisture was significantly higher in C. striata. The potassium content was significantly (p<0.01) higher in C.striata. M.vittatus shows higher content of calcium. The other trace minerals like iron, copper and zinc contents of fish did not differ significantly among the species. The vitamin A content is maximum in O.bimaculatus whereas vitamin D content is higher in Mystus vittatus. The palmitic acid was significantly (p<0.01) higher in M. vittatus. The oleic acid was significantly (p<0.01) higher in C. striata and W. attu. The linoleic acid content was significantly (p<0.05) higher in P. hypophthalmus. One of the important PUFA i.e. DHA was significantly higher in O. bimaculatus and C.striata. The PUFA content was significantly (p<0.05) higher in O.bimaculatus and P.hypophthalmus. Among the amino acids, arginine, histidine, threonine and isoleucine were higher in P.hypophthalmus. C.striata and W. attu contain high amount of Tryptophan. Glutamic acid was high in O.bimaculatus and Aspartic acid was high in C. striata. The energy content was maximum in P. hypophthalmus. The nutrient profile of these fish species revealed that they were rich in all the essential nutrients required by human being. The information on nutrient profile of fish will give a guideline to dieticians, nutritionists, medical practitioners, researchers to advice consumers to take fish in their daily diet as a health food.

The nutrient profile of five carps, viz. Labeo bata, Labeo calbasu, Labeo fimbriatus, Cirrhinus reba and Puntius javanicus were studied. The samples were collected from different geographical locations of West Bengal, Odisha and Karnataka states of India. The data on proximate composition reveal that the moisture and fat content differed significantly (P<0.01) among the carp species. The fat content is significantly (P<0.01) higher in P. javanicus, L. bata and L. calbasu compared to L. fimbriatus. However, the protein and ash content did not differ significantly among the carp species. The potassium and copper contents differed significantly (P<0.01) among the fish species. Both potassium and copper contents were significantly higher in L. bata. The calcium content was maximum in L. fimbriatus. The saturated fatty acid (SFA), mono unsaturated fatty acid (MUFA) and poly unsaturated fatty acid (PUFA) differed significantly (P<0.01) among all the carp species. The palmitic acid was significantly higher in L. fimbriatus, which is the predominant SFA. Among MUFA, the oleic acid was significantly higher in P. javanicus. The total MUFA was significantly (P<0.05) higher in C. reba. eicosapentaenoic acid (EPA) and total PUFA is significantly higher in L. bata. Among the essential amino acids, methionine was maximum in L. fimbriatus, P. javanicus and L. bata whereas in case of nonessential amino acids, the glutamic acid and aspartic acid were high in C. reba and L. calbasu. The gross energy content of the fish was higher in L. fimbriatus followed by C. reba and L. bata. The nutrient profile of these fish species reveal that they were rich in essential nutrients required for human healthSAARC J. Agri., 16(1): 215-231 (2018)

Fish Pass

AbstractAlthough small benthic freshwater fish species are an important biological component of fish assemblages and free instream movement is indispensable for their survival, they are often neglected in fish pass performance studies. In this study, a capture-mark-recapture approach was used to assess whether small bottom-dwelling species, including gudgeon (Gobio gobio), stone loach (Barbatula barbatula), spined loach (Cobitis taenia) and bullhead (Cottus gobio), were able to cross a pool-and-weir fish pass in a regulated lowland river. Some tagged individuals of stone loach (18%), gudgeon (7%) and spined loach (2%) managed to successfully ascend the fish pass under study, despite the fact that water velocity levels in the different overflows of the facility (between 0.55-1.22 m/s) exceeded the critical swimming speed of all three species. Although this suggests that a pool-and-weir fish pass is a able to facilitate upstream movement of some small benthic species in a regulated river, more detailed research incorporating advanced tagging and retrieving techniques is necessary.
