Abstract: Nutritional Analysis of the firmed fish species named Pangas (Pangasianodon hypophthalmus), Mrigal (Cirrhinus cirrhosus), Carfu (Cyprinus carpio ) from cultured ponds, wholesale markets and local retail markets were studied in order to evaluate their percentage of moisture, protein, fat, ash. The study focused on the proximate composition and the mean value of moisture was 72.86% in Pangas, 75.16% in Mrigal, 73.23% in Carfu. In case of ash the average value was 1.75% in Pangas, 2.25% in Mrigal, 2.23% in Carfu. The mean value of fat content was 8.17% in Pangas, 3.56% in Mrigal and 7.11% in Carfu. It was observed that the average value of protein were 15.30% in Pangas, 20.89% in Mrigal and 18.10% in Carfu. Each of these three fishes was collected from 9 different sources. We collected these species from Cultured ponds, Wholesale Markets and Local Retail Markets. Highest amount of moisture content was 79.57% in Pangas (Pangasianodon hypophthalmus), Ash and Fat variation was highest in Pangas (Pangasianodon hypophthalmus) fishes, Protein variation was highest in Mrigal (Cirrhinus cirrhosus).
