稻田养鱼是一种传统的养鱼方式,到目前为止,大部分地区还只停留在维持水域生态平衡,利用稻田的原初生产力进行粗放养殖的阶段,致使稻田养鱼无法获得高产。只有在利用稻田的原初生产力和改变稻田生态环境的基础上,通过投饵施肥,鲤科鱼类的多品种混养等一系列技术措施,实行稻田精养,才能进一步提高稻田鱼产量。稻田养鱼的精养方式是由“粗放”和“精养”统一而成的,可以概括为“水、种、饵、管”四字方针。一、“水”。是稻田小生态环境中主要的环境因子,直接影响稻鱼产量。一般养鱼稻田的水质较肥,透明度小,浑浊度大,浮游生物光合作 Farming of fish in paddy fields is a traditional way of fish farming. Up till now, most areas have remained at a stage of maintaining the ecological balance of the waters and using the primary productivity of paddy fields for extensive breeding, resulting in high yield of fish farming in the paddy fields. Only by using the primary productivity of paddy fields and changing the ecological environment of paddy fields, paddy field cultivation can be further enhanced through a series of technical measures such as fertilization of fertilizers and polyculture of carp species. The intensive way of fish farming in paddy field is made up of “extensiveness” and “intensive cultivation”, which can be summarized as the four-character principle of “water, species, bait and pipe”. First, “water.” Is the main environmental factor in the small ecological environment of rice fields, which directly affects the output of rice fish. The general quality of fish farming more fat, less transparency, turbidity, plankton photosynthesis
