Salmon Pre-Harvest Welfare Indicators

Developing validated welfare indicators for salmon in the period before harvest enables objective assessment and continuous improvement in pre-slaughter welfare.

Key Facts

Pre-harvest crowding, transport, and handling cause acute welfare costs for salmon
Validated indicators including skin condition, fin erosion, and eye damage assess welfare outcomes
Cortisol measurement requires invasive sampling complicating welfare monitoring
Behavioural indicators including swimming posture and surface breathing are measurable
Real-time monitoring systems could enable automated welfare assessment in commercial operations

Welfare Considerations

Without validated pre-harvest welfare indicators, improvements cannot be objectively measured or compared between operations. Developing practical, validated tools for pre-harvest welfare assessment enables evidence-based improvement and supports meaningful certification claims.
