黄山浮溪、香溪和浦溪上游鱼类资源现状的调查研究

通过对黄山的浮溪、香溪和浦溪三条溪流上游的鱼类组成现状进行了调查和研究,结果表明,目前这三条溪流上游鱼类共计15种,隶属于3目、7科和13属,浦溪中的鱼类物种数量(15种)明显高于浮溪(7种)和香溪(6种);浮溪和香溪尽管分属不同水系,但其鱼类在组成上却具有极高的相似性。同历史数据相比,目前黄山溪流鱼类多样性明显下降,分别从水坝的建立、沿岸生境的破坏、非法捕捞和水质污染四个方面对该变化趋势进行了讨论,并提出了有关开展黄山溪流鱼类保护的建议措施。

Investigation to the upstream fish compositions of lake Fuxi, Xiangxi and Puxi in Huangshan mountain

The upstream fish compositions of lake Fuxi,Xiangxi and Puxi in area of Huangshan mountain were primarily investigated.It was found that all the fish catched involving 15 species,belonging to 3 orders,7 families and 13 genuses.The species in lake Puxi,amounting to 15,were markedly higher than those of lake Fuxi and Xiangxi,7 and 6 respectively.In spite of the difference in their water-system,lake Fuxi and Xiangxi were similar in their fish composition.Compared with the historical data,the fish diversity of Huangshan mountain was decreased significantly for four causes such as the building of dams,the destruction of coastwise habitats,the unscientific catching and the water pollution.In order to effectively protect fish resources in Huangshan mountain,some recommendations were also given.
