I agree the survival rate is very high if not gill hooked and few are. We have released quite a few beside the boat with a gaff hook twist or a pair of pliers and most all of them did well. Spoons with a single hook are easy to release. After the fish is a little tired out, keep your boat speed up and it will often calm down and swim beside the boat. Study the fish and avoid netting it if it is not clipped, so a small number may get off while you are checking them out, it’s not like you won’t ever catch another one. I was very impressed with how resilient salmon are when we were clipping Coho fry. You see them netted in a group and lifted out like a little purse seiner, drugged, squeezed hard by adults and children, dropped on the table and concrete floor, rolled around and picked up with blunt fingers, and yet an hour later 100% of them are swimming around looking no worse for wear in the tanks.
