Salmon Pre-Slaughter Welfare Assessment Tools

Pre-slaughter welfare assessment in salmon requires validated indicators that can be applied at commercial scale.

Key Facts

Salmon slaughter typically follows crowding, pumping and transport to the processing plant
Pre-slaughter stress compromises both welfare and fillet quality through elevated cortisol
The Salmon Pre-slaughter Welfare Assessment (SPARE) project developed practical indicators
Behavioural and physiological measures including respiration rate and injury score are used
Effective stunning immediately following harvest is the most critical welfare intervention

Welfare Considerations

Pre-slaughter crowding and handling cause significant acute stress and fear in salmon. The window between harvest and slaughter is a high-risk welfare period. Validated assessment tools enable farms and processors to identify and address welfare problems before they cause unnecessary suffering.

What You Can Do

Support salmon certification schemes requiring pre-slaughter welfare assessment
Choose certified farmed salmon with documented humane slaughter standards
