R A S - Recirculating Aquaculture Systems

Recirculation Facts

  • Significantly reduced water consumption and effluent volumes (95%-99.9%)
  • Minimal influent water consumption allows for cost effective treatments to improve water quality and prevent the ingress of disease.
  • Minimal effluent volumes result in the ability to treat both effluent water and sludge to meet sustainability objectives.
  • Full control of culture temperature is possible, allowing for year-round production independent of fluctuating environmental or influent water conditions.
  • A high degree of control over culture conditions enables operators to optimize fish growth and feed conversion, increased production, and improve product quality.
  • Are often mechanically and operationally complex than other types of culture systems.
  • Initial capital investment is typically higher but cost of production is typically lower than in other culture systems.
  • Therapeutic treatments are efficient and economical as dosage is maintained in the system due to minimal water exchange.
  • Facilities can be located almost anywhere. Site selection is not tied to access to large volumes of water.
  • System and technology performance have been proven by successful facilities in a wide range of aquaculture applications.
