Amino acid composition of the flesh of brackish-water kutum (Rutilus frisii), warm-water silver carp (Hypophthalmicthys molitrix) and cold-water rainbow trout (Oncorhynchus mykiss) was determined. Glutamic acid showed the highest amount of amino acids measured in this study rather than other amino acids. The content of essential amino acids in rainbow trout (9.98) and kutum (9.72) was higher than the value in silver carp (8.78). Also, the proportion of essential amino acid to non-essential amino acid for the three species showed a slight difference (ranging from 1.03 to 1.19), and the highest amount was for kutum (1.19). The results indicated the advantages of amino acid quality of fish of different species in human diet. Evaluating the effect of intrinsic and extrinsic factors on amino acid composition could be advisable for future studies.


Key words: Amino acid profile, kutum, silver carp, rainbow trout.
