ABSTRACT: Genus Meretrix of Family Veneridae, contributes about 80% of the total clam catch along the south west coast Maharashtra, India. The great clam, Meretrix meretrix is the major contributor in the catch and has formed vast beds in the estuarine areas of the coast. As the abundance of these clams was showed seasonal fluctuations, the meat quality was also reported to vary. Present work was undertaken to study the seasonal variations in the biochemical composition and the percentage edibility of these clams to ascertain the meat quality. Decline in the percentage edibility observed from September to January. Percentage edibility remained high during April to October showing a good meat quality during this period. Higher protein and lipid values were recorded during the post monsoon months, with corresponding decrease in carbohydrates. Consequent increase in moisture was noted post monsoon months.
