    摘要:

    九段沙湿地是典型的长江口沙洲,对长江和东海鱼类资源有重要的影响。为了解九段沙湿地鱼类多样性及变化趋势,于2009至2012年对其进行了16次调查,结果显示:(1)4年在九段沙湿地捕获鱼类12477尾,共96种,新记录鱼类15种;(2)结合历史资料,至2012年底九段沙湿地共记录鱼类158种,以鲈形目种类居多,有54种;鲤形目次之,共27种;(3)优势种有斑尾刺虾虎鱼(Acanthogobius hasta)、(Liza haematocheila)、棱(Liza carinatus)、刀鲚(Coilia ectenes)、凤鲚(Coilia mystus)和中国花鲈(Lateolabrax maculates);(4)上沙、中沙和下沙鱼类组成存在差异,盐度是影响鱼类组成结构的重要因素。研究表明九段沙湿地鱼类资源较丰富,具有长江口鱼类区系特征,但鱼类多样性呈逐年降低的趋势,种类组成也逐年在发生变化。

    Abstract:

    Jiuduansha wetland is a typical shoal in Yangtze River estuary, which has a very important influence on fishery resources of Yangtze River and East China Sea. In order to comprehend community diversity and its variation trend, 16 surveys from 2009 to 2012 were made, and the results showed that(1)A total number of 12477 individuals were collected belonging to 96 species including 15 new records. (2) Combining with historical data, there were 158 fish species in Jiuduansha wetland, the Order Perciformes was at a dominant position, whose species were 54, the Order Cypriniformes ranked only second to the order Perciformes, comprising 27 species. (3)The dominant species were Acanthogobius hasta, Liza haematocheila, Liza carinatus, Coilia ectenes, Coilia mystus and Lateolabrax maculates. (4)Differences of fish?composition existed in Shangsha, Zhongsha and Xiasha, which revealed that salinity was a very import factor resulting of the difference in fish composition. This research showed that fishery resources of Jiuduansha wetland are abundant, and its fish composition has the typical ichthyofauna trait of Yangtze River estuary.But the diversity of fish species has declined year by year, and changes happened in its fish composition year by year.
