Abstract

Japanese rose bitterling, <I>Rhodeus ocellatus kurumeus</I>, is an endangered freshwater fish in Japan. Both the expansion of the habitat of an alien subspecies, <I>R. o. ocellatus</I>, and the increased chances of hybridization between the two subspecies have threatened the genetic identity of <I>R. o. kurumeus</I>. To conserve <I>R. o. kurumeus</I> in Kagawa Prefecture, 17 populations were genetically monitored in 2006. Two individuals in a pond were found to harbor <I>R. o. ocellatus</I> type mitochondrial DNA through PCR-RFLP analysis. Then the contaminated population was transplanted to a closed Bio-top water system to prevent contamination in other ponds. Three-day pond drying was found to be insufficient to eradicate <I>R. ocellatus</I>.
