In western colorado, we only have roundtail chubs and humpback chubs. And they are found only in the colorado river. Even though the roundtail is extremely overpopulated and destroying the rest of the fishery (squawfish, catfish, and trout in the mid areas), we have to release them as soon as caught. So basically, we can't use chubs here. We don't have any other species of chub here and none occupy any of our lakes. I don't know how a chub would work for bait.
