Freshwater Fish Catch-and-Release Welfare

Catch-and-release fishing has significant welfare implications for fish. Evidence-based handling practices can substantially reduce harm.

Key Facts

Catch-and-release fishing is practiced by millions of anglers globally and keeps most fish alive
Fish experience physiological stress responses including cortisol elevation during catch
Air exposure is the most damaging welfare factor - even 30 seconds significantly impairs recovery
Barbless hooks cause less injury and are more easily removed than barbed hooks
Water temperature affects recovery rate - fish in warmer water have higher post-release mortality
Landing nets with knotless mesh cause less scale and fin damage than knotted mesh
Studies show survival rates of 90%+ are achievable with best-practice handling

Welfare Considerations

Catch-and-release welfare depends almost entirely on angler behaviour. The difference between poor and best-practice handling can mean the difference between rapid recovery and delayed mortality. Key welfare improvements are simple and free: no air exposure, quick and gentle hook removal, and brief recovery time before release. Barbless hooks reduce injury and improve welfare outcomes. The angling community has significant capacity to improve welfare through education and cultural change.

What You Can Do

Never hold fish out of water for photography - keep them submerged even while unhooking
Use barbless hooks or crimp barbs before fishing to reduce injury
Use knotless mesh landing nets and wet your hands before handling fish
Release fish into calm water facing upstream and support them until they swim away actively
