峡江水利枢纽对赣江中游鱼类资源影响的预测分析

The Predicative Analysis about the Effects of Xiajiang Water Control Project on Fish Resourse in the Middle Reaches of Gan River

于2008-2009年就赣江中游峡江水利枢纽工程建设对鱼类的影响进行采样调查,共记录鱼类71种,隶属7目16科58属,其中以鲤科鱼类为主。峡江水利枢纽工程淹没区涉及到鱼类产卵场、越冬场、索饵场,文中就该工程的兴建对赣江中游鱼类资源可能产生的负面影响进行预测分析,提出了修建鱼道、进行水库生态调度、人工增殖放流等对策措施,旨在为赣江鱼类资源的保护提供科学依据。

The fish resources in the middle reaches of Gan River was examined from 2007 to 2009.A total of seventy-one fish species were sampled,belonging to 7 orders,16 families and 58 genera.The cyprinids represented the major species.The construction of Xiajiang hydro project will refer to the fish spawning ground,wintering ground and feeding ground.The adverse Impact of this project on fish resources were analysized.The countermeasures of building fish passage facilities like fishway,implementing the reservoir ecological operation and developing artificial propagation were put forward.It may play an important role in fish protection of Gan river in the future.
