Shorthead redhorse (Fishes of the Upper Green River, KY)

Shorthead redhorse

Moxostoma macrolepidotum

Summary ⁴

The Shorthead Redhorse (Moxostoma macrolepidotum) is a wide-ranging species in North America that needs to be monitored throughout its range. The Shorthead Redhorse is native to central and eastern North America. However, its range has expanded to include areas like the Hudson estuary and Grayson County, Texas. It inhabits small to large rivers and lakes, and lives in the benthic zone. Shorthead Redhorse feed on benthic invertebrates and can consume plant material from the benthic environment...

Distribution ⁵

Global Range: Mississippi and Missouri river basins, Great Lakes-St. Lawrence River basin, many drainages of southwestern Hudson Bay basin, and Atlantic slope from the Santee drainage north to Hudson drainage (Lee et al. 1980), from Quebec to Alberta, south to Wyoming, Oklahoma, northern Missouri, Illinois, northern Ohio, and New York, and along the east coast south to South Carolina. Ozark and Ohio River basin populations are now regarded as distinct species, M. pisolabrum and M. breviceps (Nelson et al. 2004).

Habitat ⁶

Habitat Type: Freshwater

Comments: Rocky pools, runs, and riffles of small to large rivers, natural lakes, and impoundments. Spawns usually over gravel in runs and riffles; may move out of larger bodies of water into smaller rivers and streams to spawn (Lee et al. 1980, Scott and Crossman 1973).

Justification

This species is listed as Least Concern in view of the large extent of occurrence, large number of subpopulations, large population size, and lack of major threats. Trend over the past 10 years or three generations is uncertain but likely to be relatively stable, or the species may be declining but not fast enough to qualify for any of the threatened categories under Criterion A (reduction in population size).
