Abstract
Gross biochemical composition and condition index were investigated in two geographically separated populations of the baby clam, Marcia opima during December 1998 - January 2000. Proteins, lipids, total carbohydrates and glycogen showed similar patterns of the variation according to the reproductive cycles in clams from both the areas, highlighting the importance of the reproductive cycle and physiological features of the species and also the influence of environmental conditions in determining biochemical composition. Proteins and lipids were maximum in the mature clams and decreased during and after spawning. Lipids were higher in females. Seasonal variations of lipid were inversely related to glycogen contents. Total carbohydrates and glycogen increased during summer and decreased during monsoon. Condition index was influenced by environmental conditions, which further determined the spawning season.
