Brant, I fish the Salmon as well. At least in this years set of rules, they define a marked fish on the Salmon as one whose dorsal is less than 2 1/8" (I think thats the measurement). I do know that it is almost impossible to mistake a hatchery fish for a wild fish on that river because every hatchery fish I have caught has a deformed and stubby dorsal. My guess is that definition will stay until the Quinaults are forced to adipose clip all of their hatchery fish.
