The unmarked steelhead has a better chance in the water than lets say getting hit over the head. Also I do not think a C.O. would believe you, that you did it for the fish's sake. I do not know what the fine is nor do I want to. Let it go!!! pure and simple. And yes let nature take it's course. Decaying salmon feed the river, so to will that unfortunate steellie. If we start making room for the honest besure those without remorse would kill them all.
