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 mode, demonstrates the advantages of environmental friendliness, high efficiency and sustainable development, has been widely used worldwide; they are also expected to be more applied in industrial future our natural resources decreasing. However, RAS imposes very requirements on operating conditions, including temperature, salinity, dissolved oxygen, pH, stocking density, light, feed composition, feeding amount, frequency, disinfection methods. Each factor is critical stable operation system. Therefore, ensure efficient RAS, its influencing factors must controlled within appropriate ranges. Herein, affecting reviewed, mechanisms their influence reared organisms revealed, suggestions control these proposed. This review can provide theoretical basis for further development RAS.
