Research on some biological aspects of mud crab Scylla serrata
of Pelita Jaya Bay was conducted between February to August 2012. Mud crab samples were obtained from local fisher from Pelita Jaya Village before sold. Majority of (53.20%) mud crab caught have the carapace width between 12-14 cm with 12.cm being the dominant one. There was a high relationship between carapace width-weight relationship with negative allometric growth pattern. The sex ratio showed monthly variation but not different statistically, with overall sex ratio of male to female was 1.04:0.96. Condition factor also also showed monthly variation but not statistically different. Estimation of 50% mean size at first maturity revealed that female mud crab reaches their first sexual maturity at the mean size of carapace width of approximately 12.00 cm with the smallest berried female caught of 9.60 cm carapace width.
