Animal Welfare in Sport Fishing: Catch-and-Release Ethics

Catch-and-release fishing is widely practised as a conservation-friendly alternative to retention, but evidence that fish experience pain means welfare obligations apply to how fish are handled and released.

Key Facts

Fish have nociceptors, demonstrate pain behaviour after injury, and show analgesic-sensitive responses — evidence of pain capacity
Catch-and-release survival rates depend critically on handling time, air exposure, and water temperature
Removing fish from water for photography causes physiological stress equivalent to running a marathon
Barbless hooks reduce injury and enable faster release compared to barbed alternatives
Lure fishing typically causes less injury than bait fishing due to reduced deep hooking

Welfare Considerations

The ethics of catch-and-release fishing depend on how it is conducted. Well-practised catch-and-release — using barbless hooks, minimising air exposure, keeping fish in water during unhooking, avoiding fishing in very warm water when oxygen is low — achieves high survival rates with minimal welfare harm. Poor practice — holding fish out of water for extended photography, deep-hooking through use of bait, fishing in thermally stressed conditions — causes significant suffering and mortality. The welfare obligation is to fish as carefully as possible and to avoid the practice when conditions make survival unlikely.

What You Can Do

Use barbless hooks to enable faster, less traumatic unhooking of caught fish
Minimise air exposure to under 30 seconds and keep fish in water during unhooking where possible
Avoid fishing in very warm water when dissolved oxygen is low and fish are already stressed
Support catch-and-release fishing organisations that promote welfare-informed best practice guidelines
