池塘设置网箱养鱼是可行的。首先有所需的水环境;其次是池鱼与箱鱼互不干扰。是集约化养殖的好途径;三是在风浪、灌排、增氧机的作用和高密度鱼的运动下,使箱内外水体交换频率增加,水质保持一致,箱内饵料生物能不断得到补充;四是网箱范围小,降低丁鱼类活动代谢强度,提高了合成代谢速度,有利于鱼能量的转化和积累;五是便于起捕,适时上市。 池塘网箱养鱼要注意如下技术要点。 1、养殖种类的确定。池塘网箱养鱼适宜于耐低氧的鱼类,如鲤、鲫、乌鳢、鲶鱼、淡水鲳鱼、罗非鱼等。
Pond fish cage set up is feasible. First of all there is a need of water environment; followed by pool fish and box fish do not interfere with each other. It is a good way to intensify aquaculture. Thirdly, under the action of storms, irrigation and drainage, aerator and high-density fish movement, the exchange frequency of water inside and outside the tank is increased and the water quality is consistent. The bio-food in the tank can be continuously replenished. Fourth, the cage size is small, reducing the metabolic intensity of Ding fish activities, improve the speed of synthesis and metabolism, is conducive to the conversion and accumulation of fish energy; five is easy to catch, timely listing. Pond fish cage should pay attention to the following technical points. 1, farming species to determine. Pond cage fish suitable for hypoxia-resistant fish, such as carp, crucian carp, catfish, catfish, freshwater catfish, tilapia and so on.
