| 摘 要： | 为有效保护和利用黑鲷(Acanthopagrus schlegeli)资源,本研究测定了中国近海5个群体(北方海域的营口与崂山群体,南方海域的闽清、大亚湾、东兴群体)各10尾黑鲷线粒体控制区5′端722bp序列以分析其遗传多样性和遗传结构。结果发现42个单倍型,56个多态位点;群体单倍型多样性为0.978～1.000,群体核苷酸多样性为0.0067～0.0116。中性检测和核苷酸不对称分布分析表明,中国近海黑鲷在晚更新世(165～41kaBP)曾经历过种群的快速扩张。北方群体与南方群体之间的Fst值为0.1145(P=0.00),表明存在中等程度的分化,建议将中国近海黑鲷作为两个管理单位。

| Abstract: | Acanthopagrus schlegeli is an economically important marine fish endemic in East Asia,and natural resource had been reduced dramatically. To protect and exploit the valuable fish effectively,722 bp at the 5' of mi-tochondrial DNA control region of 50 individuals collected in Yingkou(YK),Laoshan(LSH),Dayawan (DYW),Dongxing(DX) were sequenced to analyze the genetic diversity and population genetic structure of Acanthopagrus schlegeli in the coastal waters of China. Total 42 hapoltypes and 56 variable sites we... |
