Farmed Salmon Welfare Indicators Validated

Validated welfare indicators for farmed salmon are essential for meaningful welfare assessment. Research is establishing which measurable parameters most reliably reflect underlying welfare states.

Key Facts

The Fish ANimal WELfare (FANWEL) project established welfare indicators for Atlantic salmon
Validated indicators include wound scores, fin damage, eye cataracts, and crowding behaviour
Cortisol levels are a valuable research tool but impractical for routine farm monitoring
Eating behaviour monitored by camera correlates with welfare state in farmed salmon
Sentinel fish carrying welfare loggers enable continuous individual data collection

Welfare Considerations

Welfare indicators are only useful if validated against actual welfare states rather than assumed to be proxies. The development and validation of reliable, practical welfare indicators for salmon enables meaningful assessment and comparison across farms and time. This scientific foundation for welfare monitoring is as important as any direct welfare improvement.
