Peroximate composition and different types of amino acids analysis of economically important finfishes – Sardinella fimbriata, Scomberomorus guttatus in Nagapattinam Coast, Tamil Nadu, India

Abstract

The current study was undertaken to investigate the composition of peroximate in relative to season, types of sexes, and size groups in edible tissues of finfishes of Sardinella fimbriata and Scomberomorus guttatus in Nagapattinam coast, Tamil Nadu, India. S. fimbriata, indeterminates are 4-10 cm, male and females are 11-19, in S. guttatus the indeterminates are 4-12 cm, male and females are 13-24. Variations in proximate composition noticed in S. fimbriata are depicted. Moisture content ranged between 70.35 and 76.79%. Both the size groups of indeterminates (8-10 and 4-7 cm) exhibited elevated values during pre-monsoon (76.34 followed by 76.11%) and small values during post-monsoon (4-7 and 8-10 cm; 72.44 followed by 72.36%). Variations in proximate composition noticed in S. guttatus are depicted, the moisture content ranged between 70.08 and 77.88%. Both the size groups indeterminates (4-7 and 8-10 cm) exhibited elevated values during monsoon (77.88 followed by 77.05%) and minute values during summer (8-10 and 4-7 cm; 74.33 followed by 74.29%). The amino acid pleased of S. fimbriata was (91.78%), results of current study shows that the necessary amino acids (EAA) percentage was more (49.25%) than that of supplementary amino acid (NEAA, 42.76%).
