Abstract :

India is well known for its megadiversity of biological wealth harbouring over 12% of shell and fin fishes known. Aquatic biodiversity has always been playing an important role in the food and nutritional security of people especially in the rural areas.  Dahanu is the rural area along the coast of Arabian Sea. Decapod crustaceans such as crab, prawn, lobster are largely exploited in this area. Rapid urban and industrial development results in deforestation, industrial and domestic water pollution and heavy use of pesticides in agriculture declines crustaceans in this habitat. In crustaceans, the carapace length, fecundity is parameters to ascertain their reproductive maturity. Study of gonad is essential for the determination of eeding season. The present study was undertaken for the histological study of testis of the marine crab, Portunus sanguinolentus. Histologically, the testis of Portunus sanguinolentus showed small seminiferous tubules with various stages of spermatogenesis. Nutritive cells are present in between the seminiferous tubules. The process of spermatogenesis includes five distinct stages such as spermatogonia, spermatocytes, spermatids, spermatozoa and spermatophore formation.
