| 摘 要： | 采用自行设计的抽屉式生物滤器应用于漠斑牙鲆(Paralichthys lethostigma)闭合循环水养殖系统,研究其对循环养殖水的处理效果及漠斑牙鲆的增重和饲料利用率的影响。结果表明:经过60 d的循环水养殖,漠斑牙鲆从初始时的(225.4±11.9)g增加到结束时的(337.5±10.3)g,增重率49.97%;试验饲料系数1.06,养殖密度24.1 kg/m3,成活率100%;抽屉式生物滤器对于NH4+-N、NO2--N和COD去除率分别为(10.61±1.88)%、(14.90±3.06)%和(16.11±1.70)%,可满足漠斑牙鲆养殖水体的水质要求。 |

| Abstract: | A self-designed drawer biofilter used in recirculating aquaculture system for Paralichthys lethostigma,the research is about the water treatment effect of drawer biofilter,weight gain and feed utilization rate.The results show that the P.lethostigma(225.4 ± 11.9) g during follow-up of 60 days culture in recirculating system gets a weight gain rate of 49.97%(337.5±10.3) g,the feed coefficient of 1.06,rearing density reaches 24.1 kg/m3 and survival rate amounts to 100%.The removal efficiencies of drawer biofilter about NH+4-N、NO-2-N and COD are(10.61±1.88)%,(14.90±3.06)% and(16.11±1.704)%,respectively.Therefore,using drawer biofilter to breed P.lethostigma in recirculating aquaculture system is feasible. |
