Yeah, that is a creek chub. Either someone bucket stocked it or during high water events, that pond gets over flow from a creek.
If stocked into a pond with bass, creek chubs make excellent bass forage. They just can't reproduce in ponds unless those ponds have a feeder stream they can ascend and spawn in. However, I don't think they are an ideal forage species because they themselves are predacious, you can see that by their big mouths. However, when stocked into a pond with LMB, they rarely last more than a few minutes...
