Rhinichthys cataractae (Valenciennes in Cuvier and Valenciennes, 1842)

Common name: Longnose Dace

Taxonomy: available through www.itis.govITIS logo

Identification: Wydoski and Whitney (1979); Smith (1985); Hubbs et al. (1991); Page and Burr (1991); Jenkins and Burkhead (1994). In his type catalogue, Gilbert (1998) recognized three subspecies: R. c. cataractae, R. c. dulcis, and R. c. smithi; he noted that considerable work still needs to be done on the taxonomy of the species.

Size: 16 cm.

Native Range: Generally distributed above 40 N from coast to coast; occurs as far north as Arctic Circle in Mackenzie River drainage; south in Appalachian Mountains to northern Georgia and in Rocky Mountains south into Rio Grande drainage of Texas and northern Mexico (Page and Burr 1991).

Nonindigenous Occurrences: The Longnose Dace has been introduced into the Colorado River in Colorado (Walker 1993) and into Russell Fork (Pike County) in the Big Sandy system, Ohio River drainage, Kentucky (Jenkins and Burkhead 1994; Powers and Ceas 2000). It has been introduced into the upper Roanoke drainage in Virginia (Jenkins and Burkhead 1994). The species has been recorded from several sites in the Green River drainage of the upper Colorado River basin. These sites include Strawberry Reservoir, Utah (Sigler and Miller 1963; Tyus et al. 1982); and the upper Green River drainage in Wyoming including Hams Fork Creek (Baxter and Simon 1970), Lake Powell system (Tyus et al. 1982), and Flaming Gorge Reservoir system (Tyus et al. 1982) (the latter reservoir situated on the Utah-Wyoming border). It was also recorded from the San Juan River drainage of the Colorado River basin (Tyus et al. 1982), but specific locality data and state were not given.

Means of Introduction: Evidently a bait bucket release in Strawberry Reservoir in 1951 (Sigler and Miller 1963). Suspected bait bucket introduction in Wyoming (Baxter and Simon 1970) and in Kentucky (Jenkins and Burkhead 1994); possible bait bucket releases in other sites.

Status: Established in Colorado where it is abundant and widespread in the main-stem Colorado River and in transition zone riffles (Walker 1993); Tyus et al. (1982) listed it as rare in the upper Colorado River basin. An eradication program was carried out in Strawberry Reservoir, Utah (Sigler and Miller 1963), but the results of those efforts were unclear. Established an spreading in the upper Roanoke, Virginia (Jenkins and Burkhead 1994). Reported from Kentucky (Jenkins and Burkhead 1994).

Impact of Introduction: Longnose Dace hybridize with native speckled dace R. osculus in areas where Longnose Dace have been introduced (Sigler and Miller 1963). This hybrid has been recorded from Utah in the Provo River in 1942 and from the Strawberry Reservoir in Wasatch County in 1951 (Sigler and Miller 1963). It has also been recorded from areas where both species are native, such as, the Bear River Wyoming, Little Wood River, Idaho and Ross Fork at Fort Hall, Idaho (Sigler and Miller 1963).

Remarks: This species is sometimes used as a baitfish (Baxter and Simon 1970; Scott and Crossman 1973). Tyus et al. (1982) gave a distribution map of the this species in the upper Colorado basin.
