Sukumaran, K K and Neelakantan, B (1998) Maturation process and reproductive cycle in two marine crabs, Portunus (Portunus) sanguinolentus (Herbst) and Portunus (Portunus) pelagicus (Linnaeus) along the Karnataka coast. Indian Journal of Fisheries, 45 (3). pp. 257-264.
In the development of ovary of Portunus (Portunus) sanguinolentus and P. (P.) pelagicus, six maturity stages have been recognised by gross examination, i.e., immature virgins, immature resting, early maturing, late maturing, mature and spent. By microscopical studies, nine arbitrary stages have been identifed in the maturation process of ovary. In the development of testis, three maturity stages have been discernible, i. e., immature, maturing and mature. The spawning season is exended from August to May in both the species with intensive activity during December-February in the former and during January-February and September in the latter species.
