Abstract :

The fish muscles were investigated to determine the major components of the three hill stream fishes of Manipur. Proximate composition of the three fish species viz., Neolissochilusstracheyi, Labeopangusiaand Semiplotusmanipurensis were carried out. The crude protein ranges between 19.00�0.92 to 20.64�0.03. The highest total lipid was recorded in S. manipurensis(3.56�0.04) and lowest in L. pangusia (2.45�0.02). The moisture content ranges from 72.80�0.04 to 76.30�0.07. Lowest ash content was recorded as 1.20�0.04 in S. manipurensis and highest as 1.98�0.01 in N. stracheyi. Total amino acid of the three fish species varied from 104.42 to 113.92 g/100g. Total essential amino acid (EAA) was recorded as 55.08 to 66.51 g/100g and total non-essential amino acid as 46.09 to 56.74 g/100g. The most abundant amino acid in all the fish species was glutamic acid. Leucine, Lysine, Histidine, Valine, Threonine, Phenylalanine and Isoleucine were dominantly found essential amino acids in all the fish species. Knowledge of Amino acid composition of the fish is good to serve as a unique source for nutrients and enlightens the nutritive quality of these fishes.
