摘　　要：研究旨在探究安徽中华绒螯蟹种质资源状况以及资源混杂程度,以期为中华绒螯蟹资源的科学保护、合理利用以及相关产业政策的制定提供理论依据。采集了中华绒螯蟹4个养殖群体和长江野生群体共170尾样本,基于线粒体分子标记,进行种群遗传学分析。结果表明,长江野生中华绒螯蟹遗传多样性低,盲目捕捞可能造成野生资源衰退。野生群体与养殖群体间未出现显著遗传分化,存在严重的种质混杂。研究探明了长江中华绒螯蟹的资源现状,为其科学的保护提供理论依据。Eriocheir sinensis,especially the Yangtze mitten crab,is an important aquaculture species in China.In recent years,serious germplasm mixture of this species has been detected and little is known about the reasons.In this study,population genetics among wild and breeding populations of the Chinese mitten crab was comparatively analyzed based on mitochondrial marker in order to explore the germplasm mixed level.The results show that the genetic diversity of wild crab in the Yangtze River is low,and over fishing could cause the decline of wild resources.No genetic difference among the wild and breeding populations is detected,which means serious germplasm mixture.This study clarifies the resource status of Chinese mitten crab in the Yangtze River,and can provide a scientific basis for the protection of this species.
