利用线粒体细胞色素基因部分序列分析了日本本州中部静冈县三个水系中4个野生、1个再引入和5个人工饲养的濒危鲤（Hemigrammocypris rasborella）种群的种群结构和遗传多样性。我们检测到野生和圈养种群的部分遗传多样性的损失，以及在一些圈养，重新引入，甚至野生种群的疑似非土著单倍型。鉴于人口结构的揭示，我们建议，人口管理应考虑当地人口的特有性和可行性（避免近亲繁殖衰退）。
Population structure and genetic diversity were examined using partial mitochondrial cytochromebgene sequences of four wild, one reintroduced, and five captive populations of the endangered cyprinidHemigrammocypris rasborellafrom three river systems in the easternmost region of the species’ range in Shizuoka Prefecture, central Honshu, Japan. We detected loss of genetic diversity from portions of the wild and captive populations, as well as suspected nonindigenous haplotypes in some captive, reintroduced, and even wild populations. Given the population structure revealed, we suggest that the populations should be managed with consideration for both the endemism and viability (avoidance of inbreeding depression) of the local populations.
