Catch-and-release fishing is a practice where anglers catch fish and then return them to the water instead of keeping them. This method is often used to help maintain fish populations and promote sustainable fishing. It allows people to enjoy the sport without significantly impacting the ecosystem. To ensure the fish's survival, anglers typically use specific techniques, such as using barbless hooks and minimizing the time the fish spends out of water. Proper handling is essential, as it reduces stress and injury to the fish, contributing to healthier aquatic environments and preserving species like trout and bass.
