Yeah, you gotta release. WDFW does not mark all the hatchery fish with a clipped adipose. They want some of their brood stock to be returning to them also, and they figure that not clipping the fin helps it get back to the hatchery.

I just find it humorous though that such a crummy looking fish is actually wanted by WDFW for broodstock.

Seems to me, they would rewrite the law to allow for truly crummy looking fish to be kept by anglers, even if not marked. They might be doing something for the genetics of their brood stock.
