The present study was undertaken in order to determine the seasonal changes in biochemical constituents in different body tissues of freshwater mollusc, Mytilus viridis from river Godavari, near Aurangabad. The study was conducted during all the three seasons for twelve months. This study has shown that seasonality is related to significant alterations in the biochemical constituents of soft body tissues. The result showed maximum amount of protein in gonads, where as minimum protein was found in mantle, during all the three seasons. Animal showed large fluctuation in the amount of glycogen present in all the four body tissues. During the summer season, maximum amount of glycogen was found in foot, whereas in the winter season mantle and foot showed presence of highest amount of glycogen. Lipids were found to be in maximum amount in mantle and foot during summer season and gonad showed maximum values of lipids during monsoon and winter seasons.
