In a Name?
(no-koe´-miss) Native American name applied by Girard to this species
Do They Live?
Hornyhead chubs occur in all the drainages of Minnesota, but are somewhat more common in the central and south-central portion of the state. This species lives primarily in small to medium-sized streams in reaches with bottoms of sand, gravel, and boulders. They do not require clear water, but their numbers decrease as turbidity (cloudiness) increases. They are not found in lakes or large rivers. Hornyhead chubs often share their habitat with common shiners, bluntnose minnows, creek chubs, bigmouth shiners, stonerollers, white suckers, and shorthead redhorse.
Big Do They Get?
Do They Eat?
Hornyhead chubs are sight-feeders and are omnivorous (they consume both plant and animal items). The young eat mostly waterfleas and other small-crustaceans, small insect larvae (like midges) and some algae. The adults include a lot more plant matter and algae along with larger aquatic insects, crayfish, snails, and small fish.
