I've seen fish hooked in the mouth throw the hook then get snagged in some other area of the body several times. It happens when they roll up in the line, the hook pulls out of the mouth and then sticks in the fish as the line unwraps around the fish. Coho seem to do this the most. I caught one last summer that was lashed up with half a dozen wraps and the spoon was trailing behind. All these fish had obvious hook wounds in the mouth where the hook had pulled out. Is this a snagged fish? I wouldn't want to have to convince a game warden it wasn't.
