在闭合循环水产养殖系统中养殖高体革鯻的效果

The culture effects of Scortum barcoo in recirculating system

总结了浙东现代渔业示范园区和云南红河现代农业示范园设施渔业车间养殖高体革鯻的效果。在170d的养殖时间内,高体革b的养殖成活率100%,日增重率1.83g,饵料系数1.14,系统最高负载40kg/m3。单位水体产值3182.79元,毛利润率1039.73元,系统能耗占总成本的13.79%;系统中水质基本维持在NH4-N低于2.0mg/L,NO2-N低于1.0mg/L的水平。研究结果表明,高体革鯻是适合闭合循环系统养殖的优良品种。

This paper has summarized the culture effect of Jade Perch, imported from Australia in closedrecirculating system in Zhejiang Modern Fisheries Demonstration Field and Honghe National Aquacultural Demonstration Field. The survival rate was 100%, and added weight every day was 1.83g. The food coefficient was 1.14. The peak load was 40kg/m3. The output of every m2 and the rate of gross profit were 3 182.79 RMB yuan and 1 039.73 RMB yuan respectively. The cost of power consumption was 13.79% of gross cost. The concentrations of NH4-N and NO2-N of in the system were lower than 2.0mg/L and 1.0mg/L respectively for a long time. It showed that Jade Perch was a good species for closedrecirculating culture.
