Increasing demand for the frozen and canned crabmeat industry worldwide has now relied mainly on Portunus pelagicus. In Malaysia, demands of P. pelagicus in the fisheries industry have led to a growing interest on the broodstock of this particular crab species. Therefore, it is necessary to study information on the genetic diversity of P. pelagicus populations for breeding purpose. In order to examined the population structure of P. pelagicus in coastal areas of Malaysia, microsatellites markers were used because it exhibits higher polymorphism and informative than RAPD, AFLP and allozyme loci markers. Microsatellites analyses indicated low levels of genetic differentiation among the P. pelagicus populations which suggests the existence of inbreeding among different populations of P. pelagicus.
