Short barbeled grunter, Hapalogenys nitens, is an important fishery resource and it has been regarded as a target marine fish species for prospective aquaculture diversification in Korea, but sustainable fry production is not yet possible. This delay has led to an increase in the need for genetic information about this species. Furthermore, it is necessary to conserve the wild stocks for the sustainable use of the species. In this study, we report 26 novel polymorphic microsatellites with a mean of 4.9 alleles per locus. The mean observed and expected heterozygosity per locus was 0.45 and 0.50, respectively. Cross-amplification revealed variability in others two Haemulidae species. These markers developed can be a valuable tool for conservation genetics and further genetic improvement of these species.

Seven-band grouper, Epinephelus septemfasciatus, is of considerable economic value and a candidate species of aquaculture in Eastern Asia. It is necessary to monitor the stocks for the sustainable use and aquaculture of the species. Monitoring genetic variation among marine resources necessitates the development of genetic markers. Here, we report 22 polymorphic microsatellite markers with 2–16 alleles per locus. The mean observed and expected heterozygosity per locus was 0.53 and 0.57, respectively. Cross-amplification revealed variability in Epinephelus bruneus and Epinephelus akaara. The 22 markers developed can be a valuable tool for genetic conservation of this species.

Chub mackerel, Scomber japonicus, is a species of major importance to fisheries, particularly in eastern Asia. To aid in the sustainable management of this fisheries resource, we isolated eight novel microsatellite loci from the fish and examined their polymorphisms to estimate genetic variability. Genetic variability differed at each locus. The number of alleles ranged from 5 to 14, and observed and expected heterozygosity ranged from 0.43 to 1.00 and 0.50 to 0.86, respectively. One locus showed significant Hardy–Weinberg disequilibrium. No linkage disequilibrium was found. The high variability revealed in this study suggests that these microsatellite markers could prove to be a useful tool for further conservation genetics studies.
