Sukumaran, K K and Telang, K Y and Thippeswamy, O (1986) On the fishery and biology of the crab Portunus sanguinolentus (Herbst) along the South Kanara coast. Indian Journal of Fisheries, 33 (2). pp. 188-200.
The fishery of the crab Portunus sanguinolenttis along the South Kanara coast extends generally from, December to May. The catches of the species at Mangalore during 1979-80, 1980-81 and 1981-82 are estimated respectively at 102.3 t, 100.2 t and 57.0 t. The catches at Malpe during 1980-81 and 1981-82 are at 65.9 t and 44.1 t, respectively. The carapace-width-body-weight relationship does not differ between sexes. Spawning takes place throughout the season, with peaks in February and April-May. Males are in excess of females, differing though not significantly from the expected 1 : 1 ratio. Fecundity is estimated to be ranging between 0.03 million (in a specimen of 83-mm carapace width) and 0.07 million (in a specimen of 113-mm carapace width), suggesting a positive relationship between size and fecundity. The L^, and e"'' values are found respectively at 173 mm and 0.7 in males and 163 mm and 0.75 in females.
