稻田养鱼不仅是一项投资少、见效快、周期短、收益大的生产事业,而且具有“社会、经济、生态”三效益同步增长的效能,有着十分重大的意义。近年来,我国稻田养鱼发展较快。1986年全国有近1500万亩的稻田养鱼,其中四川有200多万亩,为全国之冠。成都市“六、五”期间开展各种类型的稻田养鱼面积151.97万亩,共收鱼908.63万公斤,占水产品总产量的30.28％。1987年重庆市稻田养鱼面积110万亩,平均亩产鱼20公斤,部分高产示范田块的亩产量达200～300公斤。广西水产技术推广总站承担的稻田养鱼高产试验、示范,1987
It is of great significance that fish farming in paddy fields is not only a production project with less investment, quick returns, short cycle and large profit, but also with the synergistic effect of “social, economic and ecological benefits”. In recent years, the rapid development of China’s rice field fish. In 1986 there were nearly 15 million mu of paddy field fish in the country, of which more than 2 million mu were in Sichuan, the highest in the country. During Chengdu’s “6th, 5th” period, 1,591,700 mu of various types of paddy fish farming areas were carried out, with a total catch of 9,086,300 kilograms of fish, accounting for 30.28% of the total output of aquatic products. In 1987, the area of paddy fish farming in paddy field in Chongqing was 1.1 million mu, with an average yield of 20 kg per mu. The output of some high-yield demonstration plots reached 200-300 kg per mu. Guangxi Fisheries Technology Extension Station bear the high-yielding test of fish farming, demonstration, 1987
