Aquaculture Welfare

Aquaculture RAS Welfare Advanced

Recirculating aquaculture systems offer significant welfare advantages over open net-cage farming but introduce specific welfare challenges requiring tailored management approaches.

Key Facts

RAS allows precise control of water quality parameters including oxygen, CO2, and pH
Elimination of sea lice and disease from wild fish is a major welfare benefit of RAS
Water quality failures in RAS can cause rapid mass mortality events
Fish in high-density RAS may show higher stress responses than lower-density systems
Energy intensity of RAS is a sustainability challenge distinct from welfare considerations

Welfare Considerations

RAS technology offers genuine welfare advantages through disease control and water quality management, but introduces specific risks including rapid water quality failures and high-density stress. Optimising RAS welfare requires ongoing monitoring, appropriate stocking, and robust contingency systems.
