概要:
Allozyme analysis was conducted to find out genetic diversity and structure of important fishery resources Meretrix spp. (M. lusoria, M. petechialis and Meretrix sp.) in Japan, South Korea, China and Taiwan. Samples were collected from 26 Meretrix spp. populations from Japan (20 localities), Korea (2), China (1) and Taiwan (3) between 2004 and 2008. Twelve loci from 10 enzymes were examined, and heterozygosity (He, Ho), allelic richness (A), inbreeding coefficient (Fis), pairwise Fst and Nei’s genetic distance (D) were calculated. The Taiwanese Meretrix spp. from Tanshui and aquacultured samples were consists of native species from Taiwan, because it was genetically distinct from Japanese M. lusoria. Japanese M. lusoria showed small A, low He, detective bottleneck, and these low genetic diversity was caused by drastic population decline throughout Japan after 1960’s. As a result, the degree of genetic differentiation among Japanese local M. lusoria was low. However, Mutsu, Aomori Pref, population was genetically distanced from other Japanese populations based on pairwise Fst and genetic distance. Furthermore, in the Sea of Japan M. lusoria populations, latitudinal clines were observed in the allele frequency and in He. One way gene flow between neighboring localities may explain these latitudinal clines. On the other hand, in the Pacific M. lusoria populations, the locations of samples were geographically distant from each other; however, the degree of genetic differentiation was small. The large scale of seedling release might have influenced on genetic structure of Pacific M .lusoria populations through hybridization and translocation between local individuals and introduced individuals. 続きを見る
