|Scientific Name:||Semotilus corporalis (Mitchill, 1817)|
Cyprinus corporalis Mitchill, 1817
|Red List Category & Criteria:||Least Concern ver 3.1|
|Reviewer(s):||Smith, K. & Darwall, W.R.T.|
|Facilitator/Compiler(s):||Hammerson, G.A. & Ormes, M.|
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 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).
|Range Description:||Atlantic slope, from James River drainage, Virginia, to New Brunswick; Hudson Bay, Lake Ontario and St. Lawrence drainages, Quebec, Ontario, and New York; common (Page and Burr 1991).|
Native:Canada; United States

|Population:||This species is represented by a large number of subpopulations and locations.|
Total adult population size is unknown but relatively large.
Trend over the past 10 years or three generations is uncertain but likely relatively stable or slowly declining.
|Current Population Trend:||Stable|
|Habitat and Ecology:||Clear, flowing, gravel- to rubble-bottomed small to medium rivers; lake margins. Young occur in more rapid water upstream but large adults seem to seek large pools and expanded regions of the lower reaches. Spawns over pit made by male in gravel bottom; male covers eggs, forming a mound or ridge of gravel, which may be 2 m long (may be the largest nest built by any species of fish) (see Johnston and Page 1992). Many mature males spawn as satellites of pit-ridge-building males (Johnston and Page 1992).|
|Movement patterns:||Not a Migrant|
|Major Threat(s):||Localized threats may exist, but on a range-wide scale no major threats are known.|
|Conservation Actions:||Currently, this species is of relatively low conservation concern and does not require significant additional protection or major management, monitoring, or research action.|
