Abstract

They are widely distributed from freshwater tanks, pools, rivers. This phylum comprises animals like gastropods and lamellibranch which are of high quality of edibility and of commercial importance. The direct discharge of industrial effluents and runoff exert their toxic effect on the living beings, by changing physic-chemical parameters finally, affecting the life cycle of the animals. Freshwater molluscs are filter feeder exposed to the drastic variation in surrounding aquatic media which affect the physiology and cytoarchitecture. Present study is an attempt to study effect of pesticide on gonads of the fresh water mollusk Lamellidens corrianus found in Chincholi tank near Sangola of Solapur district. (M.S.) India. During three seasons namely, monsoon, summer and winter. The present study showed severe damage to the male gonads, with increasing exposure time.
