摘　　要：为提升淡水池塘工程化循环水养殖模式中流水槽的集污率及养殖系统的自我净化效果,采用完善吸污设施、搭建生物浮床、养殖品种搭配等综合生态养殖措施,极大提升了水质稳定性,经过140 d养殖,四条水槽总产量18193 kg,平均单产53.5 kg/m^(2),平均效益79500元/hm^(2)。In order to improve the sewage collection rate and the self-purification effect of the aquiculture system in the engineered recirculating freshwater pond,the comprehensive ecological culture measures had been taken,such as improving the pollution absorption facilities,building the biological floating bed and selecting species mixtures.And these measures had greatly improved the stability of the water quality of the system.After 140 days of breeding,the total yield of the four water tanks was 18193 kg,the average yield was 53.5 kg/m^(2),and the average benefit was 79500 yuan/hm^(2).
