Aquaculture Halibut Welfare

Welfare considerations specific to Atlantic halibut aquaculture including environmental requirements and juvenile management.

Key Facts

Atlantic halibut are benthic flatfish adapted to cold, clear water
Farming halibut requires maintaining low water temperatures and high oxygen levels
Juvenile halibut metamorphosis from pelagic to benthic life stage requires careful management
Halibut are sensitive to handling and show strong stress responses during grading
Commercial halibut farming is concentrated in Norway and Iceland

Welfare Considerations

Atlantic halibut have specific welfare needs arising from their benthic lifestyle, cold water requirements, and sensitivity to handling. The species' slow growth creates economic pressure that may conflict with welfare investments. Development of species-specific welfare protocols for halibut, including appropriate density limits, handling procedures, and environmental quality standards, is needed as the industry develops.

What You Can Do

Choose halibut from farms with documented welfare management plans
Support development of halibut-specific welfare standards in aquaculture certification
Advocate for welfare assessment to be included in halibut aquaculture licensing
