Wild Fish Welfare: Catch-and-Release Recreational Fishing

Catch-and-release recreational fishing causes injury, physiological stress, and mortality in fish, with evidence-based practices that reduce welfare harm in released fish.

Key Facts

Hooking injury, air exposure, and handling cause significant physiological stress in caught fish
Post-release mortality rates vary from 2-30% depending on species, handling, and water temperature
Barbless hooks reduce injury and facilitate faster release with less handling
Keeping fish submerged during unhooking and photograph minimizes air exposure stress
High water temperatures dramatically increase post-release mortality in cold-water species like trout
Fish show pain behaviors after hooking including opercular beat increases and reduced feeding

Welfare Considerations

Catch-and-release fishing is widely practiced as a conservation-oriented approach, but the welfare implications of the practice deserve honest consideration. Fish that are hooked experience physiological stress responses, hooking injuries, handling stress, and potentially lethal air exposure. Post-release mortality means that many fish that swim away die within hours or days. Welfare-conscious anglers can significantly reduce these harms through barbless hooks, minimal air exposure, proper support of the fish during handling, and avoiding fishing in water temperatures that increase post-release mortality.

What You Can Do

Use barbless hooks and minimize handling time and air exposure when practicing catch-and-release
Check water temperatures before fishing - avoid targeting cold-water fish during summer heat
Support fishing regulations that incorporate welfare-based handling standards
Consider whether the welfare cost of catch-and-release fishing aligns with your personal values
