Description Seasonal variation in biochemical composition of Meretrix casta (Chemnitz) occurring in Vellar
estuary (Lat. 11 °29' N; Long 79°46' E), S. India was carried out monthly for a period of one year
from April '75 to March '76. Gonad recorded high percentage of carbohydrates (5.2%-9.4%) than the other body components
(viz- mantle, adductor muscle, gills, foot, siphon and digestive gland). Gonad also recorded the highest
protein value of 74.4% but mean monthly values showed that mantle had higher percentage of protein
(60.5%) than other body components. Digestive gland had high percentage of lipid (mean 3.05%) than the other body components.
Digestive gland appears to be storage organs for fat and protein. Of the seven body components studied,
gill showed very low percentage of protein (47.07%), carbohydrate (1.45%) and fat (1.73%).
Protein content of gonad registered an increase before spawning and decrease after spawning.
Thus, protein content of gonad showed seasonal changes associated with the annual reproductive cycle-
