Farmed Salmon Enrichment - Space and Complexity

Enrichment approaches for farmed Atlantic salmon in sea cages, including current creation, feeding enrichment, and structural complexity.

Key Facts

Wild salmon occupy complex riverine and marine environments with diverse sensory stimulation
Sea cage environments are relatively uniform, providing little spatial complexity or environmental variation
Current generation within cages through air injection improves swimming exercise and potentially welfare
Feeding enrichment by varying feed pellet size and timing reduces competition and improves feed utilisation
Underwater LED lighting has been shown to affect salmon schooling behaviour with welfare-relevant implications

Welfare Considerations

This topic carries significant welfare implications. Evidence-based management and timely veterinary care can substantially improve outcomes for the animals involved.

What You Can Do

Consult your veterinarian or a specialist for guidance specific to your situation
Follow evidence-based management protocols and best practice guidelines
Monitor animals closely and intervene promptly when welfare concerns arise
Stay updated with current research, legislation, and industry standards
Share knowledge with others to improve welfare outcomes across the sector
