A review of influencing factors on a recirculating aquaculture system: Environmental conditions, feeding strategies, and disinfection methods

Recirculating aquaculture system (RAS), as a modern highly intensive aquaculture mode, demonstrates the advantages of environmental friendliness, high efficiency and sustainable development, and has been widely used worldwide; they are also expected to be more widely applied in industrial aquaculture in the future as our natural resources are decreasing. To ensure the efficient and stable operation of RAS, its influencing factors must be controlled to within appropriate ranges. Herein, the factors affecting the operation of RAS are reviewed, and the mechanisms of their influence on the reared organisms are revealed, and suggestions on the control of these factors in the aquaculture are proposed. This review can provide a theoretical basis for the further development of RAS.
