[6] Utah chub are omnivorous with highly plastic diets, consuming plants, algae, and a variety of aquatic invertebrates such as dipterans, chironomids, zooplankton, and crustaceans.

During the spawn, 2–6 male fish escort each female, and externally fertilize deposited eggs on the lake or river bottom.

[11][12] Populations of Utah chub, both native and introduced, are generally viewed as nuisance due to competition with stocked gamefish such as rainbow trout (Oncorhynchus mykiss).

Although these projects can be successful, they are expensive and may not be a viable long-term management solution, as Utah chub populations may persist or be illegally reintroduced after treatment.

Some efforts to reduce Utah chub population size have included top-down control by stocking predatory fish such as walleye (Sander vitreus),[20] tiger muskellunge (Esox masquinongy × lucius),[21] and cutthroat trout (Oncorhynchus clarkii).

[7][17] These methods have also proven effective at controlling Utah chub, in some cases extirpating populations; however, this strategy may result in the establishment of predatory fish outside their native range.
