We developed 17 new microsatellite markers in Haliotis discus hannai. All loci were found to be polymorphic with an average of 13.1 alleles per locus (range 3–28). The mean observed and expected heterozygosities were 0.77 (range 0.17–1.00) and 0.79 (range 0.42–0.96), respectively. Six loci deviated significantly from Hardy–Weinberg proportions, and thus should be used with caution. The high variabilities revealed in this study suggest that these microsatellite loci should provide useful markers for studies of trait mapping, kinship and population genetics.
