To minimize harm to fish during catch and release fishing, it's essential to follow some best practices. Firstly, use barbless hooks to make unhooking easier and less damaging to the fish. Secondly, handle the fish with wet hands or a wet cloth to protect their slime coat, which is crucial for their health. Avoid touching their gills or eyes. Keep the fish in the water as much as possible, only lifting it for a quick photo if necessary. When releasing the fish, support it in the water until it swims away on its own. If the fish shows signs of exhaustion, revive it by gently moving it back and forth in the water to help oxygen flow through its gills.
