Characterization of 22 polymorphic microsatellite markers for seven-band grouper Epinephelus septemfasciatus developed using a 454 pyrosequencing approach

摘要

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.
