摘　　要：为探索斑节对虾循环水养殖可行性及应用发展价值,该研究自主设计蛋白分离组合装置、内循环流化床等关键工艺环节水净化装备,构建了技术先进、结构紧凑的斑节对虾循环水养殖系统。针对其不同阶段生长特性及水环境需求,提出一种水质调控方法,科学投喂。运行试验120d,溶解氧浓度5.30~7.14mg/L,p H值7.23~8.44,氨氮浓度0.43~1.38 mg/L(稳定运行后),亚硝酸盐氮浓度0.15~0.56 mg/L(稳定运行后);斑节对虾在循环水养殖模式水生态环境下正常生长,先后经历快速生长期、稳定生长期及缓慢生长期,终末养殖密度3.02 kg/m^(2),取得高效养殖结果;终末饲料系数1.67,单茬每平方米利润34.78元,每平方米年利润69.56元(按1年2茬计),获得良好经济效益。该实践可为斑节对虾循环水养殖模式应用提供技术支持。Penaeus monodon was one of the three main cultured prawns in the world,which had the characteristics of fast growth,large individual,strong disease resistance,a wide range of temperature and salt,delicious meat,and high market price.Guangdong,Fujian,Hainan,and other places were the main areas for rearing and breeding of Penaeus monodon in China,and the traditional extensive production method was its main production method.As the model’s shortcomings continue to emerge,this water and soil resource-dependent and ecologically destructive production method had become one of the major problems that restricted the sustainable development of Penaeus monodon.Circulating the aquaculture system was the current development direction of advanced aquaculture productivity,but so far there were still few reports on pond aquaculture and related research.In order to explore the feasibility and application development value of Penaeus monodon recirculating aquaculture,two sets of recirculating aquaculture systems composed of a pond,a protein separation unit,an inner circulating fluidized bed,and a circulating pump were designed and constructed in Rudong Base of Institute of Fishery Machinery and Instrument,Chinese Academy of Fishery Sciences in 2019,and the aquaculture experiments were carried out.The whole process of aeration aerator in the pond was started,and the whole process of water truck aerator in the later stage was running.The water circulation treatment system operated in the middle and late stages of aquaculture,and the circulation capacity was 26.50 m^(3)/h(middle stage)and 33.00 m^(3)/h(late stage).The amount of sewage discharged was 4%-10%(middle stage)and 10%-12%(later stage)of the aquaculture water body.In this paper,the key equipment was designed in detail and the circulating capacity was calculated,and the water quality condition,the growth of Penaeus monodon culture,the water purification function of protein separation combined device,internal circulating fluidized bed,and other equipment under the correspond
