在渔业水体有限的情况下,渔业的可持续增长要在养殖模式上寻求发展,增加养殖密度、提高单位水体产量、减少对养殖环境的污染。应用传统养殖技术,已难以大幅度提高单位面积产量,同时养殖效益下降、养殖环境恶化,主要养殖品种病害严重,且多呈暴发性流行。工厂化养殖应是我国发展集约化养殖和健康养殖的方向,而其中的水处理系统是工厂化养殖的核心。
In the case of limited fishery water bodies, the sustainable growth of fisheries should seek development in culture mode, increase breeding density, increase unit water production and reduce pollution to farming environment. Application of traditional farming techniques, it has been difficult to significantly increase the yield per unit area, while reducing the benefits of farming, farming environment deteriorated, the main breed serious disease, and mostly outbreaks. Industrialized breeding should be our country to develop intensive farming and healthy farming direction, and one of the water treatment system is the core of factory farming.
