Field and Stream recently had an article published about bleeding fish and releasing them. I forget the exact percentages off hand but the basic idea was if the hook cant be removed easily, cut the line and release the fish. most of the time the hook would be pushed out of the mouth and discarded within 6 days and the fish survived. Playing doctor on the fish and getting the hook out that resulted in more/severe bleeding the fish almost all ended up dying. So basically if they bleed alittle but the hook came out cleanly, let em go, it will heal up and they will be fine.
