I understand that if someone catches a hatchery steelhead, the angler must keep the fish up to four fish. Catch and release is something that I have always practiced so I do not have any experience with keeping fish. My wife is happy to know that if I catch a hatchery steelhead I will be bringing it home. I would like to know the best and humane way of "treating" the fish once pulled from the water. What exactly do I do.
