Aquaculture Welfare

Salmon Welfare in Recirculating Aquaculture Systems

Recirculating aquaculture systems (RAS) offer potential welfare benefits for salmon through controlled environments but present unique challenges requiring careful management.

Key Facts

RAS controls water temperature, oxygen, and waste removal precisely
Reduced disease and parasite pressure is a key welfare advantage over sea cages
High stocking densities possible in RAS require careful monitoring to prevent stress
Water quality failures can cause rapid welfare crises if not detected immediately
RAS salmon show lower cortisol stress responses in well-managed systems

Welfare Considerations

RAS technology can significantly improve salmon welfare by eliminating parasites, predators, and extreme weather effects, but requires robust monitoring systems and trained staff to prevent sudden water quality deteriorations.

What You Can Do

Support certification schemes that include RAS welfare standards
Advocate for mandatory real-time water quality monitoring in RAS facilities
Choose salmon products from certified welfare-conscious producers
