随着水产养殖方式向集约化转化,养殖密度和投饲量大大增加,鱼体排泄物和残饵量、施药量也相应增加,这种养殖方式对水资源的消耗大,既带来养殖自身污染,又排放大量的养殖废水污染环境。针对这种状况,该试验的目的旨在保障产品质量安全、环境友好、养殖尾水零排放的情况下,利用草鱼病害免疫生态防控技术、水质调控技术、膨化饲料投饲技术和底层增氧等技术的集成进行草鱼池塘的高效养殖。现将该试验情况简介如下。
With the conversion of aquaculture methods to intensification, the density of breeding and the amount of feeding greatly increased, the amount of fish excrement and residual bait, and the amount of pesticide applied also increased correspondingly. This method of cultivation consumes large amounts of water and brings about aquaculture Own pollution, but also discharge a large number of aquaculture wastewater pollution of the environment. In response to this situation, the purpose of this experiment is to ensure the quality and safety of products, environment-friendly, zero discharge of aquaculture tail, the use of grass carp immune disease prevention and control technology, water quality control technology, puffed feed feeding technology and the underlying oxygen The integration of technology such as grass carp pond efficient breeding. Now the test situation is as follows.
