The best way I found is to bring them close to the boat and I use a fish holder (the S shaped holder you use to hold up a fish)and try to take the hook out with out taking them out of the water.That's works for me.I find that the more there out of the water they don't make it if you try to put them back in.It's tricky but it's fun trying to get them on the side of the boat with out losing gear In less it's a really big fish I try to let them go with out taking pictures.But that's just me.But if it looks like it won't make it,in the live well it goes and then some of my family get to enjoy fresh salmon.I love catching them but hate eating them I just love the sound of a screaming reel
