Common name: Hornyhead Chub
available through www.itis.gov
Identification: Becker (1983); Robison and Buchanan (1988); Page and Burr (1991).
Size: 26 cm.
Native Range: Mohawk River system, New York, west through Great Lakes and Mississippi River basin to Red River drainage (Hudson Bay basin), Manitoba and North Dakota, south to Ohio River and lower Kentucky River system, Kentucky, but rare in unglaciated areas; south into Ozarks. Isolated populations in Platte and Cheyenne River systems, New Brunswick, Wyoming, and Colorado (Page and Burr 1991).

Means of Introduction: Lachner and Jenkins (1971) stated that collections from Elkhorn Creek of the lower Kentucky River system may represent introduction via bait fishermen or transport through stocking programs and farm pond culture. Smith (1985) suggested that its presence in the Susquehanna and Mohawk rivers of New York may be the result of dispersal through artificial canal systems (Chenango Canal). There are no historical records of Nocomis biguttatus from the Susquehanna drainage (Lee et al. 1980 et seq.). Consequently, Gilbert (personal communication) agrees that the species has been introduced there. However, since it has only appeared in that drainage very recently, Gilbert concluded that its presence is more likely the result of a bait bucket transfer rather than migration through the canal system.
Status: Established in Kentucky and New York in areas outside its native range.
Impact of Introduction: The impacts of this species are currently unknown, as no studies have been done to determine how it has affected ecosystems in the invaded range. The absence of data does not equate to lack of effects. It does, however, mean that research is required to evaluate effects before conclusions can be made.
