Yellowtail and amberjack are high-value farmed fish species whose welfare requirements reflect their active, pelagic lifestyle and size.
Yellowtail and amberjack welfare occupies a growing area of aquaculture welfare research as their production expands and premium market buyers increasingly seek welfare certification. These are large, highly active fish whose natural behavior involves constant movement through open water — sea cage confinement is inherently restrictive. The welfare priorities are managing stocking density to minimize aggression and injury, optimizing water quality for their specific requirements, controlling disease through prevention-focused management, and developing effective stunning methods for humane slaughter. The premium price commanded by these species creates a commercial environment in which welfare improvement can be linked to product quality and market differentiation.
