Five microsatellite loci are identified and characterized from the genome of Scylla serrata, a widespread and commercially important species of coastal marine crab. The loci were detected by randomly screening for di- and tri-nucleotide repeat units within a partial genomic library developed for the species. The five loci consist of dinucleotide repeats and are both co-dominant and polymorphic within the species. A sample (N = 36) of S. serrata from one Australian population has an average observed heterozygosity of 0.875 and provides no evidence of either linkage among loci or significant deviation from random mating ...

PCR products for each of the five loci were also observed from a small sample of three other species within the Scylla genus. These markers may provide genetic information that will be useful for both aquaculture and studies of natural populations of the genus.
