近年来,我国工厂化养殖发展迅速。但由于技术成熟度、运行成本和管理水平等原因,养殖密度普遍不超过50kg/m3。中国水产科学研究院渔业机械仪器研究所2010年自主设计构建的一套超高密度封闭循环水养殖系统,截至目前,以罗非鱼为主要养殖对象,单产突破100kg,单位水体养殖密度达到了113kg/m3,日换水量不到5%。超高密度封闭循环水养殖系统的成功运行,对于国内 In recent years, the rapid development of factory farming in China. However, due to technical maturity, operating costs and management reasons, breeding density generally does not exceed 50kg / m3. China Academy of Fishery Sciences Institute of Fishery Machinery independently designed in 2010 to build a set of ultra-high density closed recirculating aquaculture systems, as of now, with tilapia as the main breeding object, yield exceeded 100kg, water density per unit reached 113kg / m3, daily exchange of water less than 5%. The successful operation of ultra-high density closed recirculating aquaculture system is for domestic use
