Description :
Histological and morphological changes in gonads were studied to assess the reproductive cycle of Barytelphusa cunicularis. . The number of seminiferous tubules was counted for each section and percentage was calculated for each month. Along with these observations the seminiferous tubule diameter was noted. The observations revealed that the reproducing males of Barytelphusa cunicularis were found throughout the year. The maximum carapace length was 30-56 mm in the male was observed in breeding season. The gonad index values of B. cunicularis showed that it is annual breeder. The testis index of crab was more in June and it was less in December. In freshwater crab, spermatogenesis progressed in stages viz. primary spermatocyte, the secondary spermatocyte, the spermatid and spermatozoa. In Barytelphusa cunicularis the sperm is funnel shaped or conical cup shaped.
