池塘循环流水养殖具有高效、节能、环境友好等优点,正逐步为养殖企业所接受,并将成为未来水产养殖业现代化发展的重要方向之一。循环流水养殖是在相对封闭的环境中,利用物理和生物的方法消除养殖水体中的氨氮、硝酸盐、亚硝酸盐等,达到净化水质的目的,从而实现养殖水体自循环利用和高密度养殖。近年来,国内在池塘循环流水养殖方面开展了一系列研究和试验示范,安徽省也引进了此项技术,并在全省多个 The pond circulating water aquaculture has the advantages of high efficiency, energy saving and environmental friendliness, and is gradually accepted by aquaculture enterprises and will become one of the important directions for the modernized development of aquaculture in the future. Recycled aquaculture is a relatively closed environment, the use of physical and biological methods to eliminate aquaculture water ammonia, nitrate, nitrite, etc., to purify the water purpose, so as to achieve self-recycle aquaculture water and high-density culture. In recent years, a series of researches and experiments have been carried out in the field of pond circulating water aquaculture. Anhui Province has also introduced this technology, and in the province more than one
