池塘菜鱼共生是一种农业和渔业相结合的生态种养新技术,在基本不改变原来池塘养殖情况下,利用适合水中生长的植物,在养殖池塘上漂浮的浮床中进行栽培。浮床上植物根系从水中吸收鱼排泄物、饲料残饵等营养物质,可生产出一定数量的蔬菜,也一定程度地改善了池塘的水质,更有利于水中鱼的生长,是一种菜鱼互惠互利的共生技术。2016年甘肃省永靖县对池塘菜鱼共生技术进行试验示范,取得了较好的经济效益。
The pond fish and fish symbiosis is a new technology of ecological planting combined with agriculture and fishery. It grows in the floating bed floating on the breeding pond with the plants suitable for water growth without changing the original pond culture. Floating bed plant roots absorb fish from the water excrement, feed bait and other nutrients, can produce a certain amount of vegetables, but also to some extent to improve the pond water quality, more conducive to the growth of fish in the water, is a fish and fish reciprocity Mutual benefit symbiosis technology. In 2016, Yongjing County of Gansu Province conducted experiments and demonstration on the fish-vegetable symbiosis of ponds and fish and achieved good economic benefits.
