摘　　要：虹鳟鱼是主要的冷水性养殖鱼类之一,一般采用露天流水养殖模式。为了探究其工厂化循环水养殖模式的效果与可能性,于2022年9月—2023年4月在辽宁省丹东市辽东学院工厂化循环水养殖基地进行养殖试验。试验周期240 d,至养殖试验结束,4300尾实验鱼成活4128尾,成活率为96.00%,饲料系数为1.50±0.12,总增重率为5600.12%,养殖密度达75.89 kg/m^(3)。试验不仅为虹鳟鱼的养殖,也为其他冷水性鱼类的工厂化循环水养殖提供了参考。Oncorhynchus mykiss is one of the most important cold-water cultured fish,and it is generally bred in open-air flow-water.In order to investigate the impact and potential of the recirculating aquaculture of Oncorhynchus mykiss,breeding experiments were conducted from September 2022 to April 2023 at the factory recirculating aquaculture base of Liaodong University.The experimental period was 240 days,and by the end of the breeding experiment,4,128 out of 4,300 experimental fish had survived,with a survival rate of 96.00%.The feed coefficient was 1.50±0.12,the total weight gain rate was 5600.12%,and the breeding density reached 75.89 kg/m^(3).The experiment provided reference not only for the industrial circular water aquaculture of Oncorhynchus mykiss but also the other cold water fish.
