C. c. catostomus
The longnose sucker (Catostomus catostomus) is a species of cypriniform freshwater fish in the Catostomidae family. It is native to North America from the northern United States to the top of the continent. It is also found in Russia in rivers of eastern Siberia, and thus one of only two species of sucker native to Asia (the other is the Chinese Myxocyprinus asiaticus).
The longnose sucker inhabits cold, clear waters. It is a bottom-feeding fish, eating aquatic plants, algae, and small invertebrates. They are preyed upon by larger predatory fish, such as bass, walleye, trout, northern pike, muskellunge and burbot.
