摘 要:水产品含有丰富的蛋白质及人体所需的营养元素,随着人民生活水平的提高,水产养殖业迅速发展,为解决传统水产养殖业受环境污染、食品安全、自然灾害、疾病频发等方面的困扰,工厂化循环水养殖成为水产养殖业转型发展的养殖新模式之一。循环水养殖系统中的养殖池水体是养殖动物赖以生存与健康生长的场所,优化养殖池环境是实现鱼类等水产动物健康养成的关键。本文以建立环境友好、水质优良、资源节约、动物健康的高效绿色养殖模式为目标,以实现水产品的高品质、高产出为宗旨,综述了循环水养殖系统中水动力研究方法,以及养殖池内流场、固体颗粒物集排污、可溶性与悬浮污染物输移扩散、增氧性能、鱼类与流场相互影响等密切相关的水动力问题,并就当前循环水养殖系统水动力研究中存在的问题进行了总结,提出了加强养殖池水动力及其与结构设计、优化等关键技术的集成应用研究,以及基于养殖动物开展水动力学研究等未来发展建议,以期为循环水养殖事业的发展提供科学参考。Industrial recirculating aquaculture has become one of a new culture model for transformation and development of aquaculture industry.Particularly,optimization of the aquaculture tank environment is the key to realize the healthy cultivation of fish and other aquatic animals.It is proposed to increase the research on the hydrodynamics of aquaculture tanks and the integrated application with the key technologies such as structural design and optimization,and to carry out hydrodynamic research based on cultured animals,so as to provide a reference with the development of recirculating aquaculture.The research methods and problems of the current hydrodynamics in recirculating aquaculture system are reviewed including flow field in aquaculture tank,collection and discharge of solid particles,diffusion and transport of soluble and suspended pollutants,aeration performance,and interaction between fish and flow field,aiming to establish an efficient green aquaculture model with friendly environment,high water quality,resource saving and animal health,and high quality and high yield of aquatic products.
