摘要
鱼类增殖放流为补偿水电工程建设对急流性底栖鱼类资源量影响的重要手段之一,但在设计过程中存在若干问题。为此,探讨放流规模缺乏依据、亲鱼数量不足、鱼苗放流后存活率低等问题,并提出了相应的建议,以期为水电工程鱼类增殖放流设计提供参考。
The fish multiplication and releasing is an important mean for compensating fish resources of the lotic and benthic species in the construction of hydropower projects, but there are several problems in the design process of fish multiplication and releasing structures. These problems, such as inadequate basis for determining releasing scale, insufficient parent fish quantity and low survival rate of fish fries after releasing, are discussed herein and the corresponding recommendations are also presented to provide a reference for the design of fish multiplication and releasing in hydropower projects.
