Taxonomy: available through www.itis.govITIS logo

Identification: Cyprinella lutrensis are a deep-bodied minnow that is laterally compressed (Farringer et al. 1979, Page and Burr 2011). The mouth is terminal with a round snout (Page and Burr 1991). This species has silver sides with olive-green to blue coloration above the lateral line and a whitish abdomen (Mayden 1989, Page and Burr 2011). A dark stripe runs along the back with a dark, dusky colored dorsal fin (Page and Burr 2011). Breeding males have iridescent pink-purple-blue sides and a red crown and fins, except the dorsal fin which remains dark (Mayden 1989, Page and Burr 2011). There are 32-36 lateral scales, and the anal fin usually has nine rays (Page and Burr 2011).

Ecology: Cyprinella lutrensis are among the most widespread, ecologically general, and environmentally tolerant fish species in North America, and are highly invasive where they have been introduced outside their native range (Marsh-Matthews et al. 2011). The species thrives under harsh conditions (e.g., low flow, high turbidity, poor water quality) and aggressively colonizes severely degraded habitats. For example, introduced Red Shiners have become the most abundant species in degraded, urban streams in metropolitan Atlanta, Georgia (Devivo and Freeman 1995).

Cyprinella lutrensis spawns over an extended period of time from spring into fall months, with a peak from early to mid-summer. Breeding season in Georgia is May through July, and in south central Oklahoma and central Texas it is from April to September (Farringer et al. 1979). Spawning may occur on riffles, on or near submerged objects, over vegetation beds, or in association with sunfish nests. Some individuals breed in two successive years, but none breed their year of hatching (Farringer et al. 1979).
Adults typically school in midwater or near the surface. The species is thought to feed primarily on small invertebrates. The fish lives for 2 years in the wild.

Schultz et al. (2003) observed that the number of Red Shiners were reduced during flood events in southwestern streams (Schultz et al. 2003). Although, laboratory tests indicated that Red Shiners had equal or greater swimming ability than many of the native species (longfin dace, Agosia chrysogaster) tested (Ward et al. 2003).

Means of Introduction: The origin of most introduced Cyprinella lutrensis populations can be attributed to bait bucket releases. Koehn (1965) mentioned that the species has been introduced as a forage fish. The Red Shiner is also in the aquarium trade (Becker 1983, Etnier and Starnes 1993). It has been marketed in a pet shop under the name "rainbow dace" (Moore et al. 1976). According to Dill and Cordone (1997), it was introduced into northern California as a forage fish, not as a bait minnow as suggested by Kimsey and Fisk (1964). The introduction into the Yadkin drainage, North Carolina, was possibly the result of an aquarium release (Moore et al. 1976). Hubbs (1954) reported this species as established in the lower Colorado River basin by 1953. He attributed the source of the introduction to escapes from the Arizona Fish Farms in Ehrenburg, Arizona. There apparently has been more than one subspecies introduced into the southwestern United States. Hubbs (1954) also noted that Red Shiners found in the lower Colorado River basin were intergrades between the subspecies C. l. lutrensis and C. l. suavis. In contrast, Minckley (1973) reported that the Arizona specimens he examined more closely resembled the typical subspecies, C. l. lutrensis. Gilbert (1998) also referred it to the typical subspecies (C. l. lutrensis).

Initial introduction of Cyprinella lutrensisis is often followed by the species' rapid multiplication, dispersal, and aggressive colonization (e.g., Hubbs and Lagler 1958, Minckley and Deacon 1968, Minckley 1973). In some areas dispersal of introduced populations has been aided by the presence of irrigation ditches and canals (e.g., Jennings and Saiki 1990).

Status: Established in areas outside their native range in Alabama, Arizona, California, Colorado, Georgia, Illinois, Nevada, New Mexico, North Carolina, Utah, and Wyoming. In contrast to Hubbs and Lagler's statement (1958), Becker (1983) found that there was no evidence to substantiate the presence of this species in lagoons of Lake Michigan at Chicago.

Impact of Introduction: The Red Shiner has created a tenet among some ecologists: where it appears, native fishes disappear (Stolzenburg 1992). Dill and Cordone (1997) called the Red Shiner the second most significant threat to the welfare of indigenous southwestern fishes, after the Western mosquitofish (Gambusia affinis). Cyprinella lutrensisis are very aggressive where introduced and have been associated with impacts on the indigenous fish populations through predation, competition, hybridization, and introduction of parasites.


Ruppert et al. (1993) suggested that establishment of Red Shiner in Yampa River and Green River immediately below their confluence in Dinosaur National Monument, Colorado has led to predation on vulnerable larvae of native populations of razorback sucker (Xyrauchen texanus) and Colorado pikeminnow (Ptychocheilus lucius). This assumption was supported by a laboratory study that indicated that Red Shiner are a potential predator of razorback sucker larvae (Carpenter and Mueller 2008). In 2008, Schooley et al. (2008) found razorback sucker larvae in the guts of Red Shiners in Salt River and Sycamore Creek, Arizona.


The Red Shiner has also affected the distribution and abundance of native fishes. For example, populations in the Moapa and Virgin rivers, Nevada, have been implicated in the decline of the native fish of this region, including Spikedace (Meda fulgida), Woundfin (Plagopterus argentissimus), and Virgin River Chub (Gila seminuda) (Moyle 1976; Deacon 1988; U.S. Fish and Wildlife Service 1990). Members of this species may compete with and affect growth, condition, or survival of young Colorado Pikeminnow (Karp and Tyus 1990, Muth and Snyder 1995).


The Red Shiner may dilute the gene pools of native Cyprinella via hybridization (Mayden 1989, Burkhead and Huge 2002); studies have found that the Red Shiner is hybridizing with the Blacktail Shiner (Cyprinella venusta) in the Coosa River basin in Georgia and Alabama (Mettee et al. 1996, Burkhead and Huge 2002, Walters et al. 2007, Blum et al. 2010).


The introduction of Red Shiner into Utah was probably how the Asian tapeworm entered the Virgin River; subsequent tapeworm infestation of Woundfin may be primarily responsible for the Woundfin's decline during the 1980s (Deacon 1988). The Red Shiner is one of the species that potentially introduced the Asian fish tapeworm (Bothriocephalus acheilognathi) to the Lower Colorado River (Choudhury et al. 2004).

Introduced Red Shiner populations have contributed to the reduction of many fish populations and are known to dominate fish assemblages. For example, the introduced Redside Shiner (Richardsonius balteatus) declined when the Red Shiner became common in the Green River near the boundary of Dinosaur National Monument, Utah, in 1971 (Holden and Stalnaker 1975). In degraded streams in Georgia, introduced Red Shiners have become one of the most abundant species (Devivo and Freeman 1995). In a 1985-88 study of the Colorado and Green Rivers adjacent to Canyonlands National Park, introduced Red Shiners made up nearly 50% of the catch per unit effort (Valdez and Williams 1993).

Remarks: Several attempts have been made to eradicate the Red Shiner from a portion of the Virgin River as part of the recovery plan for Woundfin and Virgin River chubs. It was successfully eliminated from the river between Washington Fields Diversion and Johnson Diversion, but has re-invaded below Johnson Diversion (U.S. Fish and Wildlife Service 1995).

Tyus et al. (1982) provide a distribution map of this species in the upper Colorado basin. Swift et al. (1993) and Dill and Cordone (1997) detailed the history of this species in California.

Marsh-Matthews et al. (2011) examined recruitment and survivorship of Red Shiners 'introduced' to native communities in mesocosm experiments, and found that predation by piscivorous fishes (e.g., centrarchids) can limit the ability of Red Shiner to establish itself within a community.

Although hybridization with Blacktail Shiner has been reported in areas where Red Shiner are introduced, Higgens et al. (2015) found little evidence for hybridization (using both genetic and morphological data) in two river systems where both species natively occur in sympatry.

Glotzbecker et al. (2016) examined cytochrome-b variation across the native and introduced range of Red Shiner, identifying four distinct regional genetic lineages; introduced populations in the western United States were founded by introductions from the mid-west and western clades, whereas introductions in the eastern United States were solely derived from colonists from the mid-western clade.
