Assessment of genetic disturbance via hybridization in marine fishes by artificially introduced exotic populations

利用线粒体DNA和微卫星DNA标记，对日本近海温带花鲈的杂交遗传干扰进行了研究。在高知县采集的几个标本被推测为日本本土温带石斑鱼与人工引进的中国温带石斑鱼的杂交品种，表明非本地种子在海水养殖中存在风险。在引进非本地种子之前，需要评估本地和非本地种群之间的遗传异质性，以及评估杂交的可能性。

Genetic disturbance via hybridization in Japanese temperate bass Lateolabrax japonicus around Japanese coastal waters was assessed using mitochondrial DNA and microsatellite DNA markers. Several specimens collected in Kochi Prefecture were inferred as hybrid between native Japanese temperate bass and artificially introduced Chinese temperate bass, indicating the risk of non-native seed in marine aquaculture. The assessment of genetic heterogeneity between native and non-native populations and the evaluation of the possibility of hybridization prior to introducing non-native seed are desirable.
