Salmon Pre-Slaughter Welfare Innovations

Pre-slaughter handling is a critical welfare point for farmed salmon. New technologies aim to minimize suffering during the kill process.

Key Facts

Traditional percussive stunning followed by bleeding is considered the current gold standard
CO2 narcosis before slaughter is increasingly opposed due to aversive properties
Electrical stunning requires precise parameters to be effective for salmon
New automated systems can stun, bleed, and chill fish in under 60 seconds
Welfare at slaughter is now a key criterion for aquaculture certification schemes

Welfare Considerations

Slaughter is the final and irreversible welfare event for farmed fish. Pain and fear at the point of death matter morally regardless of what came before. Investment in effective stunning technology is accelerating, driven by both certification requirements and consumer pressure.

What You Can Do

Choose salmon from suppliers certified by Aquaculture Stewardship Council or similar
Ask retailers about their slaughter welfare requirements from fish suppliers
Support research funding for humane fish slaughter technology development
Advocate for mandatory pre-slaughter stunning standards in aquaculture law
