Abstract

Population differentiation and relationships among 6 natural rockfish populations collected from northern coastal seas around Japan were assayed using microsatellite DNA loci. Seven loci examined were polymorphic in all populations. The number of alleles per locus ranged from 6.7 to 9.3, and the average of observed and expected heterozygosity ranged from 0.63 to 0.68, andfrom 0.66 to 0.69, respectively. The observed genotype frequencies at eachlocus were almost in agreement with Hardy-Weinberg expectations with two exceptions (P < .05). The allele frequencies of 16 population pairs were significantly different (P < .05). Genetic distance (D-A) between 6 populations ranged from 0.03 to 0.08. According to a neighbor-joining tree generated from the D-A values, the 6 populations fell into 3 clusters. These clusterswere correlated with the geographical positions of each population; larvaldispersions due to water current were also found to have an effect on these results.
