I think some of you have way too much time on your hands to be comptemplating such and issue. Fishing is a sport just like any other sport and we humans have been doing it for many many years. Cruelty? Has anyone watched ice hockey lately? Is Golf next because we kill the green (a living thing) with our clubs. Come on folks. If it bothers you, don't do it. Just about anything we do or don't do causes pain and or suffering to someone or something. Fishing (C&R) causes me much pleasure and I refuse to add suffering to that unless I fall on my behind.
