Handling & release
Use tackle strong enough to land the fish without an exhausting fight, and keep a dehooker or suitable release tool ready.
If releasing, dehook in the water when possible. Never gaff a fish you plan to release, keep air exposure brief, wet your hands, avoid eyes and gills, and support the body rather than hanging the fish by its mouth.
Face a sluggish fish into the current until it can swim away under its own power.
