循环水养鱼的主要特点表现在生产的连续性、无季节性和主动控制性,而主动控制养殖环境质量和营养供给是循环水养殖的核心。循环水养鱼系统由于采用先进的水处理技术和消毒杀菌技术,能有效防止养鱼过程中疾病的发生和传播,提高养殖品种的成活率和产品的品质,实现健康养殖和无公害产品生产。海水鱼类节约型工厂化养殖系统是以实用、节能、高科技为原则设计的循环水养鱼系统。 The main characteristics of circulating water fish are manifested in the continuity of production, non-seasonal and active control, while the initiative to control the quality of aquaculture environment and nutrient supply is the core of recirculating aquaculture. Because of the advanced water treatment technology and disinfection and sterilization technology, circulating water fish farming system can effectively prevent the occurrence and spread of disease in the process of raising fish, improve the survival rate of breeding species and product quality, and realize the healthy breeding and pollution-free product production. Marine fish conservation factory farming system is based on practical, energy-saving, high-tech design of the principle of circulating water fish system.
