Abstract
In the present study, variations in organic constituents in different soft body parts of Lamellidens marginalis found in Pravara River near Aurangabad was observed during different seasons. As environmental condition changes, it shows an effect on biochemical constituents in the tissues like mantle. hepatopancreas, foot and gonad. Protein is found to be maximum in gonads throughout all the three seasons, whereas mantle shows minimum values of protein. There is great fluctuation in the values of glycogen present in all the four body tissues during different seasons. During Summer Season, maximum glycogen is found in gonad, whereas during monsoon, maximum glycogen is found in foot. During winter season, maximum glycogen is observed in mantle and foot. Similarly, mantle and foot shows maximum amount of lipid during summer season and gonad shows maximum values of lipid during monsoon and winter seasons.
Keywords: Lamellidens iħarginalis,, protein, glycogen and lipid.
