安徽省中国大鲵的分布和保护现状调查

Investigation on the Status Quo and Protection of Andrias Davidianus in Anhui

中国大鲵是世界上体形最大的有尾两栖动物,是中国特有物种。问卷调查和养殖场访问的结果显示:中国大鲵在安徽省主要分布在大别山区和皖南山区。上个世纪90年代初开始,黄山地区的中国大鲵被大量捕捉。90年代中、后期开始,大别山地区也开始被大量捕捉。到上世纪末,安徽省的中国大鲵野外几近灭绝。上世纪末本世纪初,各养殖场人工繁育先后获得成功。2004年前后,安徽省开始野放中国大鲵,目前,安徽省人工养殖中国大鲵数量达数万尾。原产地确切的活体野生型中国大鲵仅约百余尾。

The Chinese Giant Salamander （CGS）, Andriasdavidianus （Cryptobranchidae）, is the World/s largest-tailed amphibian and a species uniquely existing in China. According to the results of the questionnaire survey and aquafarm interview, the CGS in Anhui is mainly distributed in Dabie Mountains and Wannan Area （south part of Anhui Province）. In the early 90s of last century, CGS in Mount Huangshan had been captured in large numbers. In the mid and late 90s of last century, CGS in Dabie Mountains began to be captured in great numbers as well. By the end of last century, the wild CGS in Anhui was nearly extinct. At the beginning of this century, the artificial CGS breeding in aquafarms has been successful. Around 2004, CGS has been set free for wild breeding. Up to now, the number of artificial breeding CGSs is reaching to about tens of thousands, while the living wild-type of CGSs in its origin （wild areas） are merely about hundreds in total.
