Length Unique Dimension of Oocytes Diameter in Gonads of Freshwater Bivalve Lamellidens Corrianus In The Course Of Pre & Post Winter Season in Konkan Area (M.S. India).

Abstract Many species of bivalve molluscs are fresh water bivalve to be had in maximum of the areas in India in mainly studied in Konkan location. Maximum of the individuals are women or hermaphrodites and no whole male turned into located. The maturation of gonads is likewise depending on the richness of food supply which depends on weather. Typically the reproductive cycle of bivalve molluscs can populace includes activation, increase and gametogenesis. The gonads are having large range of growing ova in most of the duration of the winter because enough waters are available in ponds, dams and reservoirs. The feature of the oocyte of Lamellidens corrianus it has a single massive nucleolus. The Oocytes measured between 50 to 2 hundred µm in diameter. Majority of the oocytes were between 75 to one hundred fifty µm in diameter and oocytes diameter bigger in post winter as compare to pre cold
