I have released hundreds of fish over several years without ever touching them. Not touching a fish means not squeezing its organs or accidentally rubbing off any of its protective mucous/slime, i.e., making a real difference in fish mortality. The Ketchum Release is my gift to the trout!
5 stars here. I've been using it for a long time and have not been disappointed. I wish the handle was a little longer but that's minor.
