稻田养鱼,粮鱼双丰收,早在不少省份的实践中得到证明。但过去多数还是低水平利用,形不成商品生产,因而无法显示其经济效益和发展的潜力。近几年来不少地方出现了大面积高产典型,亩产鲜鱼四五十斤至百余斤。实践证明,千斤稻、百斤鱼的典型经验,多数都出现在粮鱼高产区,若我们选用高产良田,适当扩大鱼沟鱼溜面积,并在技术上下功夫,亩产百斤鱼并非难事。我国现有3.76亿亩水稻田,如有5%(即1.880万亩)的高产良田用于养鱼,并达到亩产百斤鱼,就是94万吨,10%(即3,760万亩)的一般稻田,亩产鱼30斤,则为56.4万吨,两项合计利用稻田面积5,640万亩,即为全国稻田面积的15%,而产量就可达150.4万吨,超过1983年全国淡水渔业总产量。这个产量若 Paddy field fish, fish double harvest, as early as many provinces in the practice has been proved. However, in the past most of them were still being used at a low level and could not be regarded as commodity production, thus failing to show their potential for economic benefits and development. In recent years there have been many large-scale and high-yielding typical areas where more than four or ten pounds of fresh fish per mu to more than 100 jin. Practice has proved that the typical experience of jack-up rice and peanuts is mostly found in the high-yielding areas of grain and fish. If we choose high-yielding fertile land and properly expand the area of ​​fish-ditch fish-slip and make technical efforts, it is not difficult to produce peanuts per mu. There are 376 million mu of paddy fields in our country. If 5% (1.880 million mu) of high-yielding fertile farmland is used for fish farming and the yield per kilogram fish is 940,000 tons, 10% (37.6 million mu) Paddy fields, per mu of fish 30 pounds, compared to 564,000 tons, the two total use of paddy field area of ​​56,400 mu, which is 15% of the national paddy field area, and the output can reach 1.5 million tons, more than 1983 total output of freshwater fisheries . If this yield
