Pacific halibut aquaculture is less developed than Atlantic production but faces similar welfare challenges around handling sensitivity and slow growth rates.
Pacific halibut welfare in aquaculture settings mirrors the challenges documented for Atlantic halibut. Their extreme sensitivity to handling stress makes every interaction — disease treatment, feeding, grading, and harvest — a potential welfare event requiring careful management. The metamorphic transition from bilateral to asymmetric form is a period of particular vulnerability. Anesthesia and careful handling protocols are essential for any procedure requiring capture. Cold, well-oxygenated water that matches their natural habitat preferences reduces baseline chronic stress. The industry's relative infancy means welfare standards lag behind those for more developed species like Atlantic salmon. As production scales up, establishing welfare standards before bad practices become entrenched is essential.
