Nonindigenous Occurrences: This species is known from (and possibly introduced into) the Yadkin River system (Pee Dee River drainage) of North Carolina (Bortone 1972; Lee et al. 1980 et seq.; Menhinick 1991; Jenkins and Burkhead 1994), and the upper Cape Fear and upper Tennessee drainage (Watauga).  Museum specimens were found in the upper Cape Fear, but it was not listed as occurring there in Menhinick (1991). The first specimen from this drainage was in 1992 (NCSM 17930).  This species is thought to be introduced in the upper Pee Dee drainage in South Carolina (Hocutt et al. 1986), and was first found in the upper Santee in 1999 (NCSM 32857).  In Tennessee, it is known from the upper Tennessee drainage (Strange and Mayden 2009).  In Virginia, it is known from (and possibly introduced into) several Atlantic slope drainages including the Potomac River drainage (i.e., Straight Creek of the South Branch system and South Fork of the Shenandoah River system); the Rappahannock River drainage (sites in the Rapidan River system and upper Rappahannock proper); and the Pee Dee River drainage (Hocutt et al. 1986; Jenkins and Burkhead 1994). It is also known from (and possibly introduced into) the upper Holston River system (Tennessee-Ohio River basin) the lower James drainage, and the Upper Levisa drainage of Virginia (Page and Burr 1991; Jenkins and Burkhead 1994; Powers and Ceas 2000).

Means of Introduction: Probable bait bucket releases, multiple introductions to a drainage seem possible (Jenkins and Burkhead (1994). According to Jenkins and Burkhead (1994), the species was first recorded in the South Fork of the Shenandoah in 1956, Straight Creek in 1975, the Rapidan in 1951, the upper Rappahannock in 1974, the Pee Dee in North Carolina in 1970, the Pee Dee in Virginia in 1983-1984, and the Holston in 1966 (possibly as early as 1955). The population in the Rapidan likely came from the nearby James River. Jenkins and Burkhead noted that the availability of this species to bait seiners and its spectacular coloration increase the probability of this fish being moved about in bait buckets.

Status: Reported from, possibly established in, the Pee Dee River drainage of North Carolina. Established in Virginia in all drainages mentioned except, possibly, the Holston.

Impact of Introduction: Unknown.

Remarks: There is some uncertainty concerning the native versus nonindigenous distribution of this species. Citing Ross and Carico (1963), Starnes and Etnier (1986) stated that Holston River records of Chrosomus oreas oreas (and that of Clinostomus funduloides funduloides) were likely the result of accidental introduction, since each taken was based on a single collection of a very small number of individuals. Hocutt et al. (1986) listed it as introduced to the Pee Dee River drainage and as introduced (but possibly native) to the Rappahannock and Potomac river drainages. In his summary table on North Carolina fishes, Menhinick (1991) listed it as "probably introduced" to the Yadkin River drainage. In their summary table on Virginia fishes, Jenkins and Burkhead (1994) listed this species as "regarded as introduced, but possibly native" for three Atlantic Slope drainages (Potomac, Rappahannock, and Pee Dee) and one Ohio River basin drainage (Holston); they listed it as "regarded as native, but possibly introduced" to another Atlantic Slope drainage, the York. Jenkins and Burkhead (1994) summarized the distribution of this species in detail and discussed at length its introduction, or possible introduction, into various drainages.

Strange and Mayden (2009) recently reassigned all North American species of Phoxinus to Chrosomus.
