近年来，江苏省建湖县对稻田养鱼作了有益尝试，去年计划实施6万亩，实际完成6．5万多亩，亩平纯收入1688．4元，是单一长水稻的2．5倍以上。今年他们又提出了加速发展稻田养鱼新的要求，即1997年全县确保建成高产高效稻田养鱼基地8万亩，力争10万亩，亩产稻谷500公斤，鱼50公? In recent years, Jianhu County, Jiangsu Province, made a useful attempt to fish farming in paddy fields. Last year, it planned to implement 60,000 mu of land and actually completed 65,000 mu of land, with a net income of 1,688.4 yuan per mu, a 2.5 Times more. This year they put forward new requirements for accelerating the development of paddy field fish farming. In 1997, the county ensured that 80,000 mu of high-yield and high-efficiency paddy fish farming base were built and 100,000 mu of paddy fields were muted for producing 500 kg of rice and 50 km of fish.
