Farmed Salmon Welfare Indicators

Validated welfare indicators for farmed salmon allow objective assessment of welfare status across multiple domains of the production cycle.

Key Facts

Operational welfare indicators include lice burden, wound prevalence, and gill health scores
Behavioral indicators include surface swimming, crowding behavior, and feed response
Physiological indicators include cortisol levels, fin damage scores, and immune parameters
The SWIM welfare assessment tool integrates multiple indicators into a composite welfare score
Consumer-facing welfare labels must translate complex indicator data into accessible information

Welfare Considerations

Validated welfare indicators allow farms to identify welfare problems earlier and demonstrate improvement over time. Composite scores that integrate multiple indicators provide more comprehensive welfare assessment than any single metric.
