That looks like a rare pug-nosed trout. They're on the endangered species list and a few were illegally introduced into Strawberry about five years ago. The DWR was madder than heck, but now that they're there, they can't do anything about it since they're endangered. They've kept it under a tight lid, but now it looks like the cat is out of the bag.
I hope you immediately turned it loose or you may be in big trouble...
