摘要
Abstract
Fenneropenaeus penicillatus (redtail shrimp) is an important marine commercial animal in China.Recently,its resources have been depleted rapidly as a result of,for example,over-exploitation and environmental degradation of spawning grounds.Therefore,we analyzed the genetic diversity and differentiation of nine wild populations of F.penicillatus of China (Ningde,Lianjiang,Putian,Xiamen,Quanzhou,Zhangpu,Dongshan,Nanao,and Shenzhen populations) by amplified fragment length polymorphism (AFLP) technology,to provide genetic information necessary for resource protection,rejuvenation,artificial breeding,and sustainable use of the resource.Eight AFLP primer pairs were used for amplification,and 508 bands were detected among the populations.The results show that the percentage of polymorphic loci (P) ranged from 41.34％ to 63.58％; the Nei's gene diversity (H) of the populations was 0.119 4-0.230 5; and Sharnon's Information Index (I) was 0.184 1-0.342 5.These genetic data indicate that the genetic diversity of F.penicillatus was high.The genetic differentiation coefficient (Gsr=0.216 2) and gene flow (Nm=1.812 4) show that there was a high level of genetic differentiation and a moderate level of gene flow among populations.More studies on the genetic differentiation mechanism of F.penicillatus along the south-eastern coast of China need to be conducted to find more effective scientific protection strategies for the conservation ofF.penicillatus genetic resources.关键词
