Abstract

Mud crabs genus Scylla are distributed across the Indo-West Pacific Oceans. Among the four species, S. tranquebaricadominates the mangrove areas in Sabah, Malaysia and constitutes the primary crustacean fishery resource. Overexploitationof this economically important fisheries resource can have a significant impact on population diversity. This study wasconducted to evaluate the genetic diversity of S. tranquebarica from five important fishing grounds. The genetic diversitywas estimated based on the cytochrome c oxidase (COI) gene sequence. A total of 143 individuals were sampled across the5 fishing grounds. The findings revealed that the crabs in Sabah comprised 11 haplotypes with a mean haplotype diversity(h)of 0.5564 and a mean nucleotide diversity () of 0.0038. The molecular variance analysis (AMOVA) showed that the lowgenetic differentiation among crab individuals in the five fishing grounds. The low genetic diversity provides the basis forthe establishment of a scientific breeding program to counteract the loss of genetic diversity which is the result of over-exploitation of this ecologically and economically important fisheries resource
