Effect of Monsoon Climate in Accurate Size of Histological Variations in Gonads of Freshwater Bivalve Mollusc Corbicula regularis

Abstract

The bivalve molluscs are fresh water bivalve available in  most of the regions in India. Most of the individuals are  females or hermaphrodites and no complete male was  observed. The most of maximum species of bivalve in  various reproductive cycle times and water pollutions direct  impact of development & productive imbalance.  Particularly in Maharashtra state. Several environmental  factors such as temperature, turbidity, depth, mechanical  factor, light intensity, genetic & hormonal control. The  maturation of gonads is also dependent on the richness of  food supply which depends on climate. Generally the  reproductive cycle of bivalve mollouscan population  includes activation, growth and gametogenesis. The  histological sections of the gonad throughout the study  revealed that gonad consists of numerous follicles  innervated by the connective tissue and muscles to  determine the size of the oocyte. The present study was  totally depends on the climatic imbalance in due to  maturity of the gonads.
