Recirculating aquaculture systems, i.e. re-using water after purification recycling, are efficient, economic, and environmentally friendly. In addition, they comply with the strategic needs for circular economy, energy conservation and emission reduction, and changing mode of economic growth proposed combined with aquaculture research and industrial development, focused on breeding management and application, water circulation system carrying capacity, water cycle ratio, main breeding animals, breeding effect, perfect breeding density, and other aspects of . The findings are summarized and discussed to provide a corresponding reference for the future establishment of standard breeding management for recirculating aquaculture systems in China.
