湖泊是我国宝贵的国土资源，在26亿亩内陆水域中，湖泊面积1．1亿亩，约占40％，开发潜力很大。但长期以来，这类宜渔大水面或处于产量低、刮现率低、效率低、尚待开发状态；或开发过度，造成水质的富营养化，破坏了资源的再生能力。为此，八五期间，国家立项“湖泊渔业增养殖 The lake is China’s precious land and resources. In the 2.6 billion mu of inland waters, the lake covers an area of ​​110 million mu, accounting for about 40% of the total. There is great potential for development. However, for a long time, such large-scale fishery should be in low yield, low rate of scraping, low efficiency, yet to be developed; or over-exploitation, causing the eutrophication of water quality and destroying the regenerative capacity of resources. To this end, during the Eighth Five-Year Plan, the state project "lake fisheries by breeding
