Common name: Roanoke Darter
Taxonomy: available through
www.itis.gov
Identification: Page (1983); Page and Burr (1991); Jenkins and Burkhead (1994).
Size: 7.8 cm.
Native Range: Roanoke, Neuse, and Tar River drainages, Virginia and North Carolina (Page and Burr 1991).
Nonindigenous Occurrences:
The Roanoke Darter was introduced into the James and New River drainages in Virginia (Hocutt et al. 1986; Page and Burr 1991; Jenkins and Burkhead 1994; Stauffer et al. 1995). The population in the James River was originally considered to be native; however, due to its range expansion it is now considered to be introduced (Jenkins and Burkhead 1994). Craig Creek is the probable site of introduction. Jenkins and Burkhead (1994) gave a detailed account of the expansion of this species in the James River. The Roanoke Darter was first taken in the New River in Virginia in 1963 or 1964 midway between Claytor Dam and Bluestone Reservoir (Jenkins and Burkhead 1994). This species also is introduced in the New River drainage in West Virginia, where it spread downstream from Virginia (Jenkins and Burkhead 1994; Stauffer et al. 1995). It was first taken in West Virginia below Bluestone Reservoir in 1970 (Jenkins and Burkhead 1994).

† Populations may not be currently present.
Means of Introduction: Unknown.
Status: Established in Virginia and West Virginia. It is now the most abundant darter for a 20-mi stretch on the New River below Bluestone Reservoir (Jenkins and Burkhead 1994).
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.
