Abstract：Partitioned Aquaculture System is one of the key directions of research and development on green and efficient aquaculture facilities. In this paper, the definition of Partitioned Aquaculture System is proposed, the principle of systems design and the development history at home and abroad are expounded, and three types of system models developed abroad are summarized: Partitioned Pond Aquaculture System, Split-Ponds and In-Pond Raceways. The research progress and development trend of the three system models are systematically sorted out through literature collection and field research, and the species cultured, water circulation mode, research progress and application status in development models at home and abroad are compared. By further discussing the advantages and disadvantages of sequencing aquaculture pond and in-pond raceways with good development prospects at home, the next research focus and development direction are put forward, which can provide reference for structural optimization and technical upgrading of Partitioned Aquaculture System.
