稻田养鱼是以鱼稻共生理论为基础,以综合利用、立体开发水田资源为内容的实用养鱼技术。早在三国时代,我国就有稻田养鱼的记载,经过不断的完善、普及,如今,无论国内、国外,山区、平原,北方、南方都有稻田养鱼的存在。在朝鲜,稻田养鱼可使稻增产11％左右;在湖北,水稻增产7.8—14.3％;在四川,水稻增产13.6％。黑龙江省属于高寒地区,地理纬度、气候、光照等因素对稻田养鱼都有较大影响,再加上地大物博,所以稻养鱼一直不被人重视。只是近年来,农业面临的严峻形势逼迫我们不得不走质量效益型农业之路,并且
Paddy fish farming is based on the symbiotic theory of fish and rice, with comprehensive utilization, three-dimensional development of paddy resources as the practical content of fish culture technology. As early as in the Three Kingdoms era, there are records of fish farming in rice fields in our country.

In North Korea, paddy field fish production increased by about 11%; in Hubei, paddy yield 7.8-14.3%; in Sichuan, rice yield 13.6%. Heilongjiang Province belongs to the alpine region. Geographical latitude, climate, light and other factors have a great impact on the fish farming in the paddy field. Together with the vast territory, rice and fish have not been taken seriously. It is only in recent years that the grim situation facing agriculture has forced us to take the road of quality and efficiency agriculture and
