Microsatellite analysis of genetic diversity in 3 wild populations of Exopalaemon carinicauda
摘要
Abstract
The Exopalaemon carinicauda, subordinated to Decapoda, Palaemonidae, is an endemic shrimp species in China and is widely distributed in the coastal waters of China and west coast of the Korean Peninsula, especially in the Yellow Sea and Bohai Sea. So far, the E.carinicauda, has been studied on aq-uaculture, biology and ecology, but few reports were about population genetics. Fisheries management and conservation of this important marine species rely on a better understanding of its population genetics. So in this study, genetic diversity of 3 wild stocks, collected from Laizhuo Bay(LZ), Haizhuo Bay(HZ), Xiangshang(XS), were investigated using 12 microsatellite loci. A total of 115 alleles were detected in 12 microsatellite loci and the number of alleles ranged from 6 to 14(mean 9.583 3). The expected and observed heterozygosities in 12 loci ranged from 0.765 3 to 0.866 0 (mean 0.827 8)and from 0.216 7 to 0.717 6 (mean 0.517 5), respectively. The average polymorphic information content of 12 loci was 0.7051. Mean coefficient of gene differentiation.for loci(Fst) was 0.093 0(0.05 <Fst< 0.15) by F-statistics. UPGMA clustering tree based on D genetic distance showed that Laizhuo Bay stock was more closely related to Xiang-shang stock and Haizhuo Bay stock was farthest related to Xiangshang stock.关键词
