Farmed Salmon Spill Mortality Welfare

Equipment failures including power outages and oxygen system failures cause acute welfare emergencies in salmon farms with potential for mass mortality.

Key Facts

RAS power failures cause oxygen depletion within minutes at high stocking density
Net pen winch failures can expose fish to predators or cause crowding injury
Feed system failures cause hunger stress if prolonged
Generator backup systems are essential welfare infrastructure in RAS facilities
Emergency response protocols minimise mortality and welfare costs from equipment failures

Welfare Considerations

Equipment failures create acute welfare emergencies in salmon farms that can cause rapid, severe suffering through oxygen depletion or other system failures. Robust backup systems and emergency response protocols are welfare essentials, particularly in RAS facilities where fish are entirely dependent on technology for life support.

What You Can Do

Support certified salmon farms with robust backup system requirements
Advocate for emergency response standards in aquaculture welfare certification
Choose certified salmon from facilities demonstrating infrastructure welfare investment
