编者按:随着水产养殖业的发展和技术的进步,水产养殖的放养密度越来越高,池塘养殖作为当前我国水产养殖业最主要的养殖方式,养殖密度也在逐年增大,池塘养殖系统中含有蛋白质的配合饲料大量投入,成为集约化养殖过程中养殖动物饵料的主要来源,但未能被养殖动物摄食的残饵以及养殖动物排泄的含氮物质也给养殖生态系统的自净能力带来了沉重的压力。养殖池塘水体是水生动物赖以生存和生长的环境基础,水质管理 Editor’s note: With the development of aquaculture and technological progress, stocking density of aquaculture is getting higher and higher. Pond culture, as the most important aquaculture mode of aquaculture in our country, is also increasing its density annually. Pond aquaculture system A large amount of compound feed containing protein has become the main source of bait for farmed animals in an intensive breeding process. However, the reed bait, which is not fed by farmed animals, and the nitrogenous substances excreted by farmed animals also bring self-purification capacity to the farming ecosystem A heavy pressure. Aquaculture pond water is the aquatic animal survival and growth based on the environment, water quality management
