我国有2.6亿多亩内陆水域,除去已利用人工养殖的外,都是捕捞自然资源的场所,捕捞产量建国初期1950年为30万吨,至1960年增加到66.8万吨,创历史最高水平,十年间增长1.2倍,此后连年减产,1978年降到29.6万吨,为建国以来的最低年产量,比最高年产下降56％。湖北省由1954年的14.35万吨降到2万吨,下降86％,安徽省由8.19万吨降到1.65万吨,下降80％.内蒙古由1960年的2.56万吨降到1.304吨,下降95％。产量下降的原因,除一部分捕捞水域改为人工养殖外,主要是水域的生态环境遭到破坏,特别是六十年代至七十年代后期的近廿年尤为严重。诸如江河湖海间建闸筑坝、围湖造田,以及工业污染,水质恶化和酷渔滥捕,捕捞强度超过了资源的再生能力。所有这些,导致了鱼类资源的严重衰退。
Our country has more than 260 million mu of inland waters except for those that have used artificial aquaculture, all of which are places for natural resource harvesting. The catch was raised from 300,000 tons in 1950 to 668,000 tons in early 1950, setting the highest record in history An increase of 1.2 times over the past ten years. Since then, the annual output has dropped and dropped to 296,000 tons in 1978, the lowest annual output since the founding of the PRC, down 56% from the highest annual output. Hubei dropped from 86,300 tons in 1954 to 20,000 tons, down by 86%, while Anhui Province dropped by 80% from 81,900 tons to 16,500 tons. Inner Mongolia dropped from 25,600 tons in 1960 to 1.304 tons, down by 95% %. The reason for the decline in production was that the ecological environment of the waters was mainly destroyed except for some of the fishing areas, especially the last 20 years from the 1960s to the late 1970s. Such as the construction of rivers and lakes between the sea gate, lakes and lakes, as well as industrial pollution, deteriorating water quality and overfishing fishing, fishing intensity than the renewable resources. All of this has led to a serious decline in fish stocks.
