摘要: 循环水养殖系统作为一种新型高密度养殖方式具有养殖水体环境可控、系统运行平稳、技术安全可靠、高度节水节地等优点。本文以天津市滨海新区某企业养殖半滑舌鳎为例,对循环水养殖系统的运行效果进行分析。结果表明:半滑舌鳎的养殖密度为(20~25)kg/m2,初始平均质量为5 g,利用循环水养殖系统养殖407 d,最终平均质量为1 079 g,存活率为29.1%。通过水质检测分析,氨氮平均去除率为64%;亚硝酸盐平均去除率为58%;弧菌和细菌的灭杀率为99%;pH值保持在7.0~8.5;盐度维持在18~35。经济性分析结果表明,该海水工厂化循环水养殖系统的可行性和经济性良好,适宜在沿海地区大力推广。

Abstract: As a new type of high-density aquaculture method, recirculating aquaculture system has the advantages of controllable aquaculture water environment, stable system operation, safe and reliable technology, and high water saving and land saving. In this paper, the operation effect of recirculating aquaculture system was analyzed by taking the cultivation of Cynoglossus semilaevis in an enterprise in Binhai New Area of Tianjin as an example. The results showed that the culture density of Cynoglossus semilaevis was(20-25)kg/m2, and the initial average mass was 5 g. After 407 days of culture in recirculating aquaculture system, the final average mass was 1 079 g, and the survival rate was 29.1%. The average removal rates of ammonia nitrogen, nitrite, vibrio and bacteria were 64%, 58% and 99%, respectively. The pH and salinity were 7.0-8.5 and 18-35, respectively. The results of economic analysis show that the system is feasible and economical, and it is suitable to be popularized in coastal areas.
