Marine Animal Welfare

Marine Protected Areas and Fish Welfare

Marine protected areas benefit fish welfare by reducing fishing pressure and allowing behavioral repertoire expression in undisturbed environments.

Key Facts

Over 8% of the global ocean is currently in some form of marine protected area
Fully protected no-take reserves show fish abundance increases of 670% on average
Fish in protected areas exhibit natural schooling, spawning, and foraging behaviors
Spillover from MPAs increases catches in adjacent fished areas, benefiting fisher livelihoods
Many MPAs permit some fishing, reducing their effectiveness for fish welfare and conservation

Welfare Considerations

Marine protected areas benefit fish welfare by allowing natural behavior, reducing chronic stress from fishing disturbance, and preventing the acute suffering of bycatch and injury. Well-enforced no-take reserves are among the most effective large-scale interventions for ocean animal welfare and biodiversity simultaneously.
