摘　　要：入海河口建闸,将对水域生境和鱼类资源产生一定的影响,为了缓解工程建设给鱼类资源所带来的不利影响,需采取一定的对策措施。以曹娥江大闸为例,结合大闸工程特点、河口段水生生态现状以及工程建设对水生生物的影响等,提出了设置鱼道、开闸纳苗及增殖放流的水生生态保护对策和措施,并对有关措施进行了设计论证。The Gate built in estuary will bring some passive effects to the aquatic habitats and fish resources. In order to abate the passive adverse effects, some measures should be to taken. As an example, according to the Cao＇e River Gate＇s engineering characteristics, the actuality of the aquatic in the estuary, and the trait of the effects on the aquatic etc., the measures such as fishway, opening the gate for fry migration, and multiplication and marking, are put forward.
