Abstract :
The present study was undertaken to analyze the biochemical composition in relation to season, sex, and size groups in edible tissues of E. malabaricus in Nagapattinam coast, Tamil Nadu, India. Seasonal variations in moisture content ranged between 72.35 and 79.13%, crude protein (68.22 and 73.25%), carbohydrate (2.12 and 5.23%), crude lipid (4.33 and 7.66%) and ash content (5.25 and 8.64%) in all the size groups of both sexes. Among the size groups in both sexes, maximum carbohydrate level was recorded during postmonsoon (50-60 cm: female-5.38%) and minimum during summer (30-40 cm: male-2.85%). Low protein content was noticed in larger size groups and high values in smaller size groups. Most of the size groups in females showed higher protein content than males during all the seasons. The crude protein contents in muscle tissues of the presently studied finfishes showed a relationship with spawning season. High protein levels were observed in muscle during post and pre spawning months and low values during spawning season.
