主　　题：Fenneropenaeus chinensis release simple sequence repeat(SSR) mtDNA resource supplement 

摘      要：The resource of Fenneropenaeus chinensis has declined sharply due to excessive fishing intensity,ecological changes and *** order to supplement the fishing yield and restore resources of ***,the relevant authorities have carried out the activities of stock enhancement and *** can increase biomass and recover ***,compared with increasing biomass,there were still few reports on its effect on the recovery of *** recovery is a process related to whether the released individuals can form a reproductive *** to now,there has been a lack of evidence whether the released *** can complete the entire life history,and form reproduction *** this study,gravid female shrimp after spawning migration were captured from coastal waters of Haiyang,Qingdao,and Yellow *** identifying parentage relationships using simple sequence repeat(SSR)and mtDNA haplotype,it was finally confirmed that there were eight released individuals in the recapture *** was confirmed for the first time that at least part of the released *** can complete overwintering and reproductive migration,and maintain the migration habits as their wild ***,we infered that the released shrimp can reproduce under natural conditions,these *** can form reproductive populations theoretically if without human *** results indicated that enhancenment and release activities have a positive effect on resource recovery.
