Abstract
|
|
|
|
Seven new microsatellite markers were developed for the Pacific abalone (Haliotis discus hannai, Haliotidae), and allelic variability was compared between a wild population and a hatchery population in Yeosu, Korea. All loci amplified readily and demonstrated allelic variability, with the number of alleles ranging from 6 to 15 in the wild population and from 3 to 12 in farmed populations. Average observed and expected heterozygosities were estimated at 0.65 and 0.77 in the hatchery samples, and 0.79 and 0.87 in the wild samples. These results indicated lower genetic variability in the hatchery population, as compared with the wild population and significant genetic differentiation between the wild population and the hatchery samples (F ST=0.055, p<0.001). These microsatellite loci may be valuable for future population genetic studies and for tracking hatchery samples used in stock enhancement programs.
