The aim of the study is to determine the seasonal changes in biochemical composition (protein, ascorbic acid, RNA and DNA) in relation to heavy metal pollution of Yeldari dam in freshwater bivalve, Indonaia caeruleus. The freshwater bivalves used as bioindicators of pollution. Heavy metals (Zn, Pb, Cu, Cd and As) were determined seasonally from surface water, soil sediment and soft body tissues of Indonaia caeruleus. The biochemical composition (protein, ascorbic acid, RNA and DNA) was estimated from soft body tissues (gills, mantle, digestive glands and whole soft body tissues) of Indonaia caeruleus. The heavy metals (Zn, Pb, Cu, Cd and As) was highest during summer season and biochemical composition (protein, ascorbic acid, RNA and DNA) in gills, mantle, digestive glands and whole soft body tissues of freshwater bivalve Indonaia caeruleus was highest during monsoon season.
