Catch-and-release fishing is increasingly popular but causes documented stress and injury to fish, requiring best practices to minimize welfare impacts on individual fish.
Fish caught on hooks experience acute pain from the initial hook penetration and continued discomfort during the struggle to escape. Air exposure during unhooking causes rapid oxygen depletion and temperature stress that compounds hook injury. Studies show cortisol and blood lactate remain elevated for hours after even brief capture events, indicating prolonged physiological stress. Fish released after prolonged fights in warm water have dramatically reduced survival compared to those caught and released quickly in cool water. The welfare of fish in catch-and-release angling requires genuine consideration and behavior change.
