I think that by now the lines between wild fish and hatchery fish are so blurred as to be almost nonexistant. How many years did the state pump out unmarked hatchery fish? How many years have those hatchery fish had to 'hybridize' (if that's even an applicable term here) with wild fish? At this point, I wouldn't be surprised if every single steelhead and salmon, whether it came from the truck or the stream, were a mutt.
