SBD, I don't know about wilds getting mixed with the hatchery take, but the Nat'l fish manager at Quilcene Hatchery told me that over 40% of the spawning fish upriver of the hatchery ARE hatchery fish. At that rate, it only takes a few cycles to have the harchery dna contaminate into what they call "wild" fish.

BONK 'EM!
