| 摘 要： | 以筛选的2个可鉴别的地中海贻贝（Mytilus galloprovincialis）、厚壳贻贝（M.coruscus）及其杂交后代的PCR标记（扩增核基因Glu-5’特异片段PCR标记Me14/Me17和延伸因子1α第一个内含子区段PCR标记引物EFbisF/EFbisR）,对舟山海域3个贻贝主产区（马鞍列岛海域、浪岗山列岛海域、中街山列岛海域）采集的贻贝样本的种类进行鉴别.研究结果显示：100个马鞍列岛海域贻贝个体和30个中街山列岛海域贻贝个体均为厚壳贻贝;而54个浪岗山列岛海域贻贝样本中,16个个体（29.6%）为厚壳贻贝,38个个体（70.4%）为地中海贻贝;3个群体中均未检测到2种贻贝的杂交个体.因此,推测舟山海域地中海贻贝自然分布仅局限于局部海区,但在适宜的海区地中海贻贝可取代厚壳贻贝成为贻贝床的优势物种,舟山海域贻贝床的动态变化值得进一步关注;贻贝样本中没有检测到地中海贻贝与厚壳贻贝的杂交个体,表明调查海域可能没有杂交贻贝分布或数量极少,地中海贻贝通过杂交、基因渐渗污染厚壳贻贝基因组的风险较小.

| Abstract: | The introduction of new aquaculture species is an important pathway for the spread of marine alien species.Although introduction can promote the development of local aquaculture,it also poses potential threats to native biodiversity and the marine ecosystem.Thus,risk assessment,management and monitoring of alien species are important in native biosecurity.Mytilus coruscus,or hard-shelled mussel,is a mussel native to the Zhoushan sea area,whereas M.galloprovincialis is an alien blue mussel introduced to this... |
