Cut the line if the fish is hooked in the throat or stomach. Fish are much more likely to survive if deeply embedded hooks are left in place and allowed to dissolve. If the hook is in the jaw or lip, hold the fish gently at the base of the head just behind the gill covers and remove the hook with needlenose pliers. Be very careful not to squeeze the fish. Don't drop the fish in the boat or allow it to thrash around on the shore.
Fish bruise easily, and damage to internal organs can be fatal.
Never lift fish by the eye sockets or gills. Use both hands to support the fish's weight evenly. Wet your hands before lifting the fish. If it is necessary to set the fish down, place it on a smooth, wet surface. An unconscious fish can be revived by holding it upright in the water and gently moving it back and forth.
