Complete mitochondrial genome (mitogenome) sequences were determined for two individuals of Japanese ornamental koi carp. Interestingly, the obtained mitogenomes (16,581 bp) were both completely identical to the recently reported mitogenome of Oujiang color carp from China. Control region (CR) sequences in DNA database demonstrated that more than half (65%) of the koi carp individuals so far reported had partial or complete CR sequences identical to those from Oujiang color carp. These results might suggest that the Japanese koi carp has been originated from Chinese Oujiang color carp, contrary to the belief in Japan that the koi carps have been developed directly from carp stocks in Japan. In any case, the present results emphasize the importance of analyzing Oujiang color carp when studying the origin of koi carp.
测定了两条日本观赏锦鲤个体的完整线粒体基因组（线粒体基因组）序列。有趣的是，获得的线粒体基因组（16,581 bp）与最近报道的中国瓯江彩鲤的线粒体基因组完全相同。DNA数据库中的控制区（CR）序列表明，迄今为止报道的锦鲤个体中，超过一半（65%）的个体具有与瓯江彩鲤相同的部分或完整CR序列。这些结果可能表明，日本锦鲤起源于中国瓯江彩鲤，这与日本认为锦鲤是直接从日本鲤鱼种群培育而来的观点相反。无论如何，目前的结果强调了在研究锦鲤起源时分析瓯江彩鲤的重要性。
