摘　　要：长江流域水库密集，蕴藏着巨大的渔业开发资源。由于人口增加、耕地减少，保护土地成为国策，今后靠用耕地开挖池塘养鱼，以此来增加水产品产量，已不可能；我国传统的四大海洋经济鱼类，因过度捕捞，已不成渔汛；湖泊不断减少，江河环境受到不程度的污染，使湖泊、江河渔业产量下降。相反，随着岁月流长、人类进步、经济繁荣，人工湖———即水库将会不断增加。所以从长远看，长江流域乃至我国的渔业开发，将会逐渐地由池塘、近海、河流、湖泊转向水库，这是渔业发展的必然趋势。开发水库渔业，要在养殖方式、养殖品种等方面进行研究与开发，这样水库渔业才能持续发展，获得显著的经济与社会效益。Over the Yangtze Basin there is an aggregation of reservoires containing a big potential for the development fisheries.The protection of cultivated land is a basic policy of China because of the increasing population and the decreasing cultivated land.Accordingly,it will be impossible to increase the fishery production by way of digging fishponds at the expense of cultivated land.Our four traditional marine fishery products could no loger sustain a fishing season on account of overfishing.The reduction in the number and area of lakes and the pollution of rivers and streams to various extent caused the drop in fishery production.On the other hand,the number of artificial lake reservoir will be increasing along with the lapse of time and the prosperity of our economy.From a long term view point,our fishery development will transfer gradually from fishpond,inshore,river and lake to reservoir in the Yangtze Basin and even in the whole country.It seems to be an inevitable trend.In the exploitation of reservoir fisheries attention must be paid to research and development on the model of cultivation and fish breeding so that reservoir fisheries can develop sustainably and get remarkable social and economic benefits.
