Nutritional qualities of small fishes are a global point of research for the sustainable development of the nation. Banded gourami is a commonly available small fish widely consumed by the different communities of Kokrajhar, BTAD, Assam. These fish species are found in weedy bodies of waterlogged areas. The present study was undertaken to estimate the proximate composition, amino acid profile, fatty acids composition and selected minerals and vitamins of the small fish species Banded gourami (colisa fasciata) commonly admired by the local common peoples of Kokrajhar, BTAD, Assam. It was reported that the studied fish is having moisture, ash, protein carbohydrate and crude lipid contents are 73.1, 2.95, 17.22, 0.48 and 5.84 % respectively. The amino acid profile of the fish protein showed the highest content of the essential amino acid L-Histidine as 10.0%. The fish lipid was analysed to sort out the fatty acids and the result highlighted the presence of all the poly unsaturated fatty acids in small amounts except Palitic Acid (4.49%). Analysis of selected vitamins and minerals concluded the high content of Iron (18.23 gm) in the studied fish. It was found that the fish species colisa fasciata contained a fair content of Vitamin A (18.88 mg). The fish species colisa fasciata may be included regularly in the human diet for nutritional benefit.
