Wild Fish Welfare in Catch and Release

Catch and release fishing aims to reduce mortality but can cause significant welfare harm through handling, exhaustion, and injury. Evidence-based release practices substantially reduce the welfare impact of recreational fishing.

Key Facts

Catch and release accounts for an estimated 30-50% of all recreational fishing in the UK and US
Air exposure of fish for longer than 30 seconds significantly increases post-release mortality in some species
Barbless hooks reduce hooking injury and facilitate faster release with lower tissue damage
Water temperature affects post-release survival, with higher temperatures increasing physiological stress and mortality
Deep hooking into the oesophagus or gills causes severe injury with poor survival regardless of release method
Trout released in warm water above 20 degrees Celsius show substantially elevated mortality compared to cooler conditions

Welfare Considerations

Catch and release fishing involves a welfare compromise: angling causes stress, physical injury, and exhaustion, but good release practice significantly reduces the duration and severity of harm and the probability of post-release mortality. The welfare case for catch and release over catch and kill depends on the quality of the release practice. Prolonged fights, air exposure, improper handling, and warm water temperatures all substantially worsen welfare outcomes. Anglers who adopt evidence-based release practices, using barbless hooks, minimising air exposure, and avoiding fishing in warm conditions, act responsibly within their chosen recreation. Anglers who disregard these practices cause unnecessary welfare harm.

What You Can Do

Use barbless or debarbed hooks to reduce hooking injury and facilitate rapid release
Minimise air exposure to under 30 seconds and keep fish in water during unhooking where possible
Avoid fishing for species that cannot tolerate warm water during high temperature periods
Learn and follow species-specific catch and release best practice guidelines
Support angling bodies that promote welfare-focused release practice guidelines as standard
