摘要
多年来经过对我国部分内陆大水体进行调查和水质分析,显示:我国大水体富营养化程度非常严重,主要富营养化物质大多数为氮,氮的富营养化评价指数远大于磷的富营养化评价指数。以鲢、鳙鱼为主养对象的大水体渔业可以用来净化水质。为保护水域环境,减缓大水体富营养化,要充分发挥大水体渔业对氮、磷等富营养化物质的转化和疏导作用,基于此本文提出了不同类型和功能的大水体应采取的渔业发展策略。
For many years,the research group investigated a part of large body of water in Chinese land and the water quality analysis.The data showed that the eutrophication in large body of water in China is still rather serious.The nitrogen element(N) was the primary impact factor; Eutrophication Index of N was higher than phosphorus element(P).This study indicated that silver carp and bighead carp may be served as a means to control water eutrophication.In order to protect our large body of water against the eutrophication,it is important to play the role of large body water fisheries in transformation and counseling of N and P.This paper puts forward the policy and methods of the fisheries to the different types and functions of the large body of water fisheries.
