The kelp grouper Epinephelus bruneus (Perciformes: Haemulidae), is one of the most economically important fishery resources in Korea. This fish is regarded as a target for prospective aquaculture diversification; therefore, maintenance of stock quality is important. To investigate the effects of current artificial reproduction in a hatchery facility, genetic variation in wild-caught broodstock and hatchery-produced offspring of kelp grouper was analyzed using eight polymorphic nuclear microsatellite DNA loci; 77 alleles were identified.
Korean starry flounder, Platichthys stellatus (Pleuronectidae), is one of the most economically important fishery resources in Korea. We investigated the effect of current artificial reproduction in a hatchery facility, genetic divergence between the broodstock and their offspring populations of starry flounder in a hatchery strain to be stocked into natural sea areas was accessed using 9 polymorphic nuclear microsatellite DNA loci. High levels of polymorphism were observed between the 2 populations.
The black rockfish, Sebastes inermis (Sebastidae), is an important commercial fishery resource in Korea. As a preliminary investigation into the effect of artificial reproduction in a hatchery facility, the genetic divergence between parent and offspring populations of black rockfish was accessed using 10 polymorphic nuclear microsatellite DNA loci and a mitochondrial (mt) control gene. All loci that were screened showed marked polymorphisms. mtDNA control region sequences were also highly variable.
