2002-2003年太湖鱼类学调查

摘要:
2002-2003年对太湖鱼类学进行了调查,共采集鱼类48种(和亚种),隶属于15科、18目。比上世纪50至70年代调查的103种减少了55种。分析了鱼类种类减少的原因,主要是上世纪60年代环湖大堤和闸坝建设,阻隔了太湖和长江间的交通,以及水草湖区面积的萎缩和沉水植物的急剧减少。

Abstract:
48 species of fishes belonging to 15 family were collected and identified.Predominating among them are members of Cyprinidae, which comprise over 54% of the total number of species.From every aspect, ichthyofauna of Lake Taihu represent the typical one inhabiting stagnant water-bodies of the lower Changjiang(Yangtse) Valley.According to the survey of fish species made in 1950-1981, there were no less then 103 species in the lake.In 2002-2003, only 48 species were obtained from the lake.The cause of the diminution of fish species was chiefly that a partitive dike was built round the lake in the 1960s, thus severing the intercommunication between the Changjiang River and the Lake Taihu.The impoverishment of the submerged vagetion resource (such as the reclamation of land from the lake and fish-pen in the lake and so on ) also led to the diminution of species.On the other hand, the measures for conserving the fish resource and managements for increasing productivity of the lake are discussed.
