Abstract

We examined population genetic structure by means of microsatellite analysis among 7 Japanese flounder (Paralichthys olivaceus) populations collected from coastal sea areas around Japan. As was expected, all of the 11 microsatellite loci examined were variable in all populations (number of alleles per locus, 15.2-18.2; average of expected heterozygosity, 0.74-0.78). Eleven population pairs in 21 possible pairwise comparisons showed significant genetic heterogeneity associated with allele frequency distributions or fixation index (FST). Modified Cavalli-Sforza chord distance (DA) and Nei's standard genetic distance (DST) ranged from 0.051 to 0.090, and from 0.000 to 0.025, respectively. There was evidence that the populations assessed in this study were not drawn from a single panmictic population; however, it appears that Japanese flounder populations around Japan are not well-structured, as an estimate of the fixation index value among the 7 localities was very low (FST = 0.0025).
