Aquaculture Welfare

Aquaculture Welfare and Sea Lice Integrated Management

Sea lice management in salmon farming involves trade-offs between welfare and environmental impact. Integrated pest management approaches balance these competing considerations.

Key Facts

Sea lice cause skin damage, stress, and secondary infection in farmed salmon
Medicinal treatments including emamectin benzoate have welfare and environmental impacts
Non-medicinal treatments including warm water and freshwater are physically stressful
Biological control using cleaner fish reduces lice burden with different welfare trade-offs
Integrated management combining methods minimises both lice burden and treatment stress

Welfare Considerations

Sea lice management involves genuine welfare trade-offs. The welfare cost of lice burden must be balanced against the welfare impact of treatment. Integrated management that minimises both is the welfare-optimal approach.
