遗传多样性例如，关于淡水杜父鱼，在这些地区分布着1种Trachidermus、1种Mesocottus和11种交媾鱼。线粒体DNA分析清楚地表明，两栖，lacusbine和河流物种起源于祖先的股票降河产卵物种，如T fasciatus和交媾kazika，显示物种多样性的创造。然而，主要是由于淡水环境的迅速变化，占该地区分布的物种总数的近10- 40%的鱼类物种被发现濒临灭绝，这表明有效的保护行动的必要性。
genetic diversity. Concerning the freshwater sculpins, for example, one Trachidermus, one Mesocottus and 11 Coitus species are distributed in the regions. The mitochondrial DNA analyses made clear that the amphidromous, lacusbine and fluvial species have originated from the ancestral stocks of catadromous species such as T fasciatus and Coitus kazika, showing the creation of species diversity. Mainly because of rapid changes of freshwater environments, however, nearly 10-40 % fish species to the total number of species distributed in the regions were found to be endangered, indicating the necessity of effective conservation actions.
