Assessment of seasonal changes in biochemical composition of freshwater bivalve, Parreysia cylindrica in relation to heavy metal pollution of Jayakwadi reservoir (M.S.), India

Abstract

The objective of present study is to determine seasonal changes in biochemical content of freshwater bivalve, Parreysia cylindrica in relation to heavy metal pollution of Jayakwadi reservoir. Heavy metal concentrations were determined seasonally from surface water, soil sediment and soft body tissues of freshwater bivalve, Parreysia cylindrica. The heavy metal concentrations in surface water, soil sediment and soft body tissues of Parreysia cylindrica were highest during summer season than winter and monsoon season. The Protein, DNA, RNA and Ascorbic acid content were estimated during summer, monsoon and winter season from mantle, gills, digestive glands and whole soft body tissues. In the present study Protein, DNA, RNA and Ascorbic acid content were highest during monsoon than summer and winter season.
