【摘要】：随着我国水电事业的飞速发展,鱼类资源正面临着极大的威胁,鱼类救护工程越来越受到重视。从增殖放流、过鱼设施、栖息地保护等三个鱼类救护工程的角度,浅谈了我国鱼类救护工程的现状:增殖放流工程备受关注,放流规模与投入资金大幅度上升,但实际效果不够突出;过鱼设施建设近年来呈快速发展态势,初期监测过鱼效果较好,但是否达到设计要求尚无定论,缺乏过鱼效果评价的科学体系且相关管理法规不到位;鱼类栖息地保护工程开始被重视,在研究尝试之后已经取得一定的效果。建议相关部门审慎对待对增殖放流的投入、加强放流鱼种鱼苗及实际效果的研究评估;增加过鱼设施投入资金并加强过鱼设施的建设和研究,完善实际过鱼效果评估方法,加大鱼道运营管理执法力度;加大对栖息地保护方式的研究投入,使被破坏的鱼类栖息地得到恢复。
[Abstract]:With the rapid development of hydropower industry in China, fish resources are facing a great threat, fish rescue engineering has been paid more and more attention. In this paper, the present situation of fish rescue engineering in China is discussed from the point of view of three fish rescue projects, namely, proliferating and releasing projects, fish crossing facilities and habitat protection. But the actual effect is not outstanding enough; In recent years, the construction of fish overfishing facilities showed a rapid development trend, the initial monitoring of fish effect is good, but whether to meet the design requirements has not been decided, there is no scientific system of fish effect evaluation and the relevant management regulations are not in place; Fish habitat protection project has been paid attention to, and has achieved some results. It is suggested that the relevant departments should treat the investment of proliferation and release carefully and strengthen the research and evaluation of the fish fry and its actual effect. Increase the investment of fish facilities and strengthen the construction and research of fish facilities, improve the actual fish effect evaluation method, and increase the enforcement of the operation and management of fish channels; Increase research on habitat protection to restore damaged fish habitat.
