    • Abstract


      Reproductive cycle of the crabOcypoda macrocera has been studied employing the gonad index method. Breeding period in this crab is found to be a prolonged one extending from March–September with small intermittent peaks and falls. Salinity is found to have a close relationship with the breeding cycle as lower salinities during October–January coincided with the absence of reproductive activity. Male crabs have not shown any clear picture in their gonad index in relation to breeding period and male gametes are found round the year.
