稻田养鱼应以水稻为主,兼顾养鱼。这一指导思想是根据稻鱼共生理论,利用人工新建的稻鱼共生关系,将原有的稻田生态向更加有利的方向转化,达到水稻增产鱼丰收的目的。根据促进水稻增产兼顾养鱼的指导思想,我们认为稻田养鱼应以草鱼为主(50％-70％),因地制宜搭配一些鲤和尼罗罗非鱼等。 Paddy fish should be mainly rice, taking into account the fish. This guiding principle is based on the symbiotic theory of rice and fish, the use of artificial new rice symbiotic relationship, the original paddy ecology to a more favorable direction, to achieve the purpose of increasing yield of rice fish purposes. According to the guiding ideology of boosting rice yield and keeping fish at the same time, we believe that grass carp should be mainly used in paddy fields (50% -70%), and some common carp and Nile tilapia should be used according to local conditions.
