Behavioral welfare in net pen aquaculture fish extends beyond health parameters to include space use, swimming patterns, and environmental enrichment that supports positive behavioral states.
Net pen fish behavioral welfare is an emerging area moving beyond health-focused welfare assessment toward understanding what positive behavioral welfare looks like for fish living in managed environments. Fish in net pens with behavioral diversity - varied swimming depths, access to current gradients, and social structure - show more naturalistic behavior patterns than fish in homogeneous pen environments. The welfare science is developing welfare indicators based on behavioral patterns rather than only health outcomes, providing a more complete picture of fish quality of life in commercial aquaculture settings.
