Wild Freshwater Fish Welfare in Angling

Angling impacts the welfare of freshwater fish through hook injuries, exhaustion, and handling; best practice catch-and-release techniques minimise harm.

Key Facts

Approximately 3.4 million people participate in freshwater fishing in England and Wales annually.
Fish nociception and stress responses to angling have been demonstrated in multiple research studies.
Common carp, barbel, and trout show physiological stress markers for hours following catch-and-release.
Barbless hooks reduce injury and facilitate faster hook removal, improving welfare significantly.
Appropriate catch-and-release technique — wet hands, brief air exposure, and recovery in water — reduces mortality.

Welfare Considerations

The welfare of fish during angling involves multiple potential sources of harm: hook penetration, exhaustion from fighting the line, physiological stress from handling and air exposure, and injuries from inappropriate release. Research confirms that fish experience stress and potentially pain during and after angling. Best practice catch-and-release significantly reduces welfare impact: barbless hooks penetrate less deeply and remove more easily; brief air exposure (under 30 seconds where possible) reduces physiological stress; returning fish to water to recover before release supports survival. Anglers who invest in best practice equipment and technique demonstrate that the sport and welfare are compatible.

What You Can Do

Use barbless hooks to reduce injury and facilitate faster, easier hook removal.
Wet your hands before handling any fish to protect their protective mucus coating.
Keep fish in water as much as possible during unhooking and minimise air exposure time.
Support research into fish welfare and engage with angling organisations promoting best-practice guidelines.
