You don't. Unless it's painfully obvious, there's no real way to tell if a Quinault fish is wild or not, since most are not clipped.

Like I said, I'm a hypocrite.

I let go all wild steelhead in our WDFW regulated waters, but....

Put me on the Quinault, and I won't lose any sleep at night by taking home a fish for the BBQ, regardless if it has its fins or not.

Besides, the fish I took home was a hatchery fish. Was easy to tell, as the fins were far from perfect and all messed up. Oh, and don't assume I took home any of those pictured fish. Many other fish were caught that I'm not showing. I only show the cool fishies!

Damn fine eatin' fish, though! Yum! Yum!
