The Korean rockfish Sebastes schlegeli is a valuable recreational and commercial fish in China, and is cultured in land-based tanks and net cages. Fifteen microsatellite markers were developed for this species, and their polymorphisms were examined in a population. The allele number of the 15 markers ranged from 2 to 13, with an average of 5.933 per locus. The observed and expected heterozygosity values ranged from 0.063 to 0.938 (averaging 0.585), and 0.062 to 0.908 (averaging 0.642), respectively.
The Korean rockfish (Sebastes schlegeli) is an important commercial fish that is widely used in aquaculture. We isolated and characterized 18 polymorphic microsatellite loci from the Korean rockfish using a (GT)13-enriched genomic library. Polymorphism was assessed in 48 individuals from a single population collected from the northern coastal waters of the Yellow Sea. The observed and expected heterozygosities ranged from 0.0244 to 0.7660 (mean 0.4194) and 0.0244 to 0.8758 (mean 0.5002), respectively.
