Abstract
Chi-square values for the pooled data were significant at a probability level of 0.05 indicating that there was significant variation in sex ratio in P.{P) sanguinolentus and P. (P) pelagicus. The fecundity increased with the size of the crab from 0.044 to 1.19 x 10' eggs in P.{P) sanguinolentus and from 0.056 to 1.07 x 10' eggs in P. (P) pe/agicus and the correlation coefficient values were significant at P:;O.OOI level between the parameters studied. The productivity was found to increase from a low of 0.1 in 80-90 mm to a maximum of 2.2 in 120-130 mm in the former and 130-140 mm in the latter species.
