Abstract: One of the typical model of high-density seawater aquaculture system is recirculating aquaculture system. It is an emerging aquaculture mode which synthesizes multidisciplinary knowledge, such as biology, informatics, engineering, fluid mechanics and so on. Compared with the traditional aquaculture mode, it breaks through the limitations of external conditions including climate and hydrology. And it covers a smaller area with higher utilization rate of water resources and discharges almost no pollution to the environment, which make it become an important way to realize the sustainable development of fishery. However, in our country, there are currently so many researches on the breeding of fish fry, water treatment technology and the improvement of breeding equipment, ignoring the research on the flow field characteristics of culture pond and their interaction with fish. This paper reviews the development status of recirculating aquaculture system at home and abroad, the research method of aquaculture tank flow field, and the interaction between flow field and fish, and summarizes the shortcomings of the current researches on aquaculture tank flow field, which can provide reference for the improvement of aquaculture facilities and the optimization of aquaculture environment in the future, so as to realize the efficient and clean production of recirculating aquaculture system.
