“以水养鱼”是众所周知的道理,但水利部科学研究院水库渔业研究所运作一年的“以鱼养水”试验近日获得了成功,这意味着我国的常规淡水渔业的养殖模式将发生根本性转变。 这一新模式的主要做法是,首先放养一定数量的食鱼性鱼类如鳜鱼,让它吃掉水库里的野杂鱼;野杂鱼减少,使浮游动物大幅增加,它们又再吃掉水中大量的浮游植物;这样一来,水的透明度就会变好,水中主要污染成分的氮和磷也会减少。同时, It is a well-known truth to “fish in the water”, but the successful trial of “watering fish with water”, operated by the Institute of Reservoir Fisheries, the Chinese Academy of Water Resources Ministry of Water Resources, means that the breeding mode of China’s conventional freshwater fisheries will occur Fundamental change. The main approach of this new model is to first stock a certain amount of fish-eating fish such as catfish, allowing them to eat the trash in the reservoir, reducing the number of wild trash fish and increasing the zooplankton and eating them again Large amounts of phytoplankton in the water; thus, water transparency will be better, and nitrogen and phosphorus, the major pollutants in the water, will also be reduced. Simultaneously,
