Fish Welfare in Recreational Angling

Catch-and-release angling is practised by millions globally, with scientific evidence informing debates about fish pain, stress responses, and the effectiveness of release practices.

Key Facts

An estimated 1 million anglers regularly fish in the UK, with catch-and-release common in freshwater fishing
Fish show physiological stress responses to capture including elevated cortisol that persists for hours after release
Hooking injuries to sensitive lip and mouth tissue cause measurable distress in fish
Water temperature, air exposure, and handling time significantly affect post-release survival
Best practice including wet hands, minimising air exposure, and immediate release reduces mortality and suffering
Catch-and-keep angling, where legal, raises separate welfare questions about humane dispatch methods

Welfare Considerations

Recreational angling welfare depends substantially on the practices employed during and after capture. The evidence for fish pain and stress responses is now sufficiently strong that anglers have an ethical obligation to minimise suffering through best-practice handling and rapid release. Where fish are retained for eating, humane dispatch through spiking or priest use is both more ethical and produces better eating quality than leaving fish to suffocate.

What You Can Do

Use wet hands and minimise air exposure when handling fish for catch-and-release
Use barbless hooks to facilitate easier hook removal and reduce hooking injury
Carry a priest or spike for immediate humane despatch of fish you intend to keep
Avoid angling in high water temperatures (above 18 degrees C) when fish stress and mortality risk is higher
