Abstract: Bivalve was found in Indian waters the reproductive cycle and gonad development of the freshwater bivalve Corbicula striatella as studied over a period of 24 months (January 2016-december 2016). At the regular reproduction molluscs in India. Eapecially in Maharashtra state, in diocious Corbicula striatella the gonads are common structure in other species of phylum molluscs. Those species are collected from girna dam, Tal- Chalisgaon Dist – Jalgaon. Due to the higest oocyte diameter are shown by the winter season and then after slightly significant decrease on diameter in monsoon and then lowest diameter are observed in summer season. As per the variations of Previtelogenic and Vitellogenic oocytes in different seasons. Such as Winter season on Prewinter the previtellogenic oocytes diameter 57.227±3.136 to 63.486±5.170&Vitellogenic oocytes diameter 60.963±2.136 to 63.486±5.170 and Postwinter on a Previtellogenic oocytes diameter 61.418±3.259 to 75.223±6.480 and Vitelogenic oocytes diameter 115.428±5.524 to 125.568±4.490 then Monsoon season on the Premonsoon Previtellogenic oocytes diameter 47.117± 2.136 to 33.386±4.170& Vitellogenic oocytes diameter 51.763 ± 2.155 to 58.456±5.570 and Postmonsoon Previtellogenic oocytes diameter 51.412±3.249 to 655.217±5.458, Vitelogenic oocytes diameter 98.428±4.524 to 105.468±3.470 and Summer Presummer season, thats Previtellogenic oocytes diameter 44.325±2.236 to 50.465±5.160 & Vitellogenic oocytes diameter 48.763±2.178to51.445±4.265 and Postsummer Previtellogenic oocytes diameter 47.318±3.563to63.183±5.4520 and Vitelogenic oocytes diameter 92.428±5.248 to90.568±3.458 diameters of oocytes are observed. (All values are in μm.).
