Conservation
Environmental pollution, reservoir conditions, etc. have propagated the decline of native Japanese Rosy bitterlings in various places. Also, because the numbers of black basses and bluegills increase in such places, the amount of food availability for rosy bitterling declines.
Since R. o. kurumeus (Nippon baratanago) is critically endangered, non-profit organizations and study groups were established in Japan to help protect this subspecies.
Yao study group, one of the Japanese rose bittering conservation group, started activities for protecting endangered Nippon baratanago. For example this organization (Yao city, Osaka) made the protection pond in May 1999 where 41 male and 60 female Nippon baratanago were released with prawns. Also, 45 fresh-water mussels were transplanted at the same time. They monitored and collected data regularity through 2001. In 2000 they succeeded in increasing the Nippon baratanago population to 6000 individuals and they transferred 500 individuals to another 5 ponds from the protected pond. However, in 2001 few individuals were collected. Due to the poor water quality this year compared to previous years, the study group concluded that eutrophication has a negative effect on reproduction in the Rosy bitterling. Since then, Yao study group has considered designing new purification system to conserve Japanese native rosy bitterling. They also educate children (as an environmental study) CHANGE THIS for the next generation.
