A correct catch and release method Funny I was taught to not ever touch the gills. Removel of the slim in that area or around the eyes will cause the fish to have a high degree of getting an infection. Which could kill the fish slowly or blind it. I agree that after any long battle to keep the fish in the water for a minute or two before removing to take photo. If you are not taking a photo to keep the fish in the water and remove the hook and release if you are in slow water or a lake. Take it over to slow water if you are in fast water. Funny how we all seem have diffrent thoughts on this subject.
