摘要：

摘要：长江下游流域是中国湖泊最多的地方，气候温暖湿润，兼有暖温带和亚热带等多样性气候条件，水产养殖条件得天独厚。来自世界各地的水产养殖物种都有可能在长江下游地区找到适合生长的栖息地。因此，进行长江下游流域水产养殖外来物种调查研究对完善我国外来入侵水产养殖生物信息数据库和环境风险评估体系具有十分重要的意义。2005年6月-2007年6月，笔者采用文献调研、实地考察与专家咨询相结合的方式在长江下游流域范围内对水产养殖外来物种入侵现象进行了调查研究。结果表明，目前长江下游水产养殖外来物种共计45种，其中鱼类33种、贝类4种、甲壳类7种、两栖类1种；外来物种多来源于美洲，传播途径多为有意引进。

Abstract:

Abstract: The lower reaches of Yangze River is one of the central areas of freshwater shallow lakes in China and has the diversity climates ,such as warm temperate zone and sub-tropical zone, which make it become one of the best areas for aquaculture, therefore nearly all of the aquaculture species from the world can live in the area. So it is important for perfecting alien aquaculture species information data-base and environmental risk assessment system to investigate and study the aquaculture alien species in the lower reaches of Yangze River. The results showed that the number of aquaculture alien species in the lower reaches of Yangze River is 45 species, including 33 species of fishes, 4 species of shellfish, 7 species of crustaceans and 1 species of amphibian. Most of alien species are from America and the main transmitting way is intentional introducing.
