Taxonomy: available through www.itis.govITIS logo

Identification: Cyprinella whipplei is a shiner fish with a laterally compressed body and a small subconical head (Ross 2001). The mouth is oblique and terminal to subterminal. The pharyngeal teeth are hooked, with narrow serrated surfaces. The eyes are small. The back and sides are blue to olive green, and the flanks are silvery. The breast and belly are completely scaled. The lateral line is decurved and completely pored. The dorsal and lateral scales are strongly outlined with melanophores, creating a cross-hatched pattern. The dorsal and ventral profiles of the body are similarly curved. The greatest body depth is in front of the dorsal fin origin. The dorsal fin origin is above or slightly posterior to the pelvic fin origin. There are nine anal rays. It can be distinguished from other members of the Cyprinella genus by the base of its caudal fin, which is not milky white.

Size: 16 cm.

Native Range: Mississippi River basin, from Ohio and West Virginia to Illinois, Missouri, and eastern Oklahoma, and south to Northern Alabama and northern Louisiana; Black Warrior River system (Mobile Bay drainage), Alabama. Native to Monongahela, Little Kanawha, and Kanawha below the falls, Guyandotte, Big Sandy, small Ohio River tributaries in West Virginia, and the main channel of the Ohio River (Stauffer 2007). Mostly absent from Coastal Plain (Page and Burr 1991).

Ecology: Cyprinella whipplei inhabits low-to-moderate gradient streams that have permanent flow (Ross 2001) as well as medium to large sized streams (Miller and Robison 2004). It occurs in streams with sand or gravel substrates, such as riffle or pool segments (Ross 2001). This species has been recorded in streams with temperatures as low as freezing (Felley and Hill 1983) and as high as 25.0°C (Risch 2004). Cyprinella whipplei generally feeds on insects in the water column, and changes its diet seasonally (Ross 2001). They feed on terrestrial insects that fall into the stream in the summer and fall. Cyprinella whipplei shifts to feeding on benthic invertebrates during colder weather. During the winter and spring, they also feed on organic detritus. It preys on small crustaceans, mites, and earthworms (Stauffer 2007). Piscivorous animals such as gar, bass, sunfish, sturgeon, large chubs, kingfisher, heron, and turtles are known to feed on shiners (Mayden pers. comm. 2013). Spawning occurs between June and August. Most Cyprinella whipplei reaches sexual maturity after their second summer, but most do not spawn until after their third summer. They spawn in the crevices in logs and roots. Females who are ready to spawn move to a spawning log and may be approached by several males. Males compete with each other for the spawning female. Usually one male is successful in driving the other males away. The successful male mates with the female by pressing her against the spawning log. Males are territorial and defend their nest from other males. They display threats to males swimming near their nest by raising their dorsal fins and parallel swimming, or hitting the other male with their snouts.  It is able to hybridize with Cyprinella camura in Greenleaf Creek. Cyprinella whipplei possesses alarm substances in their epidermal cells that are released when damaged, which chemically alert conspecifics to perform a fright reaction that may increase their chances of survival in the face of predators (Smith and Smith 1983). These alarm substance cells are lost during the spawning season. It has been suggested spawning may cause epidermal damage, and the absence of these alarm cells prevents the release of alarm substances during spawning, a situation where a fright reaction is not necessary for conspecifics.

Means of Introduction: Likely bait bucket release (Miller and Robison 1973).

Cyprinella whipplei has a moderate probability of introduction to the Great Lakes (Confidence level: High).

Potential pathway(s) of introduction: Dispersal

Cyprinella whipplei occurs in the Mississippi River basin, Ohio River, Muskingum River, and the Fox River drainage, which are near waters connected to the Great Lakes basin (Page and Burr 1991, Retzer and Batten 2005, Sanders 1992). There are electrical barriers between the Great Lakes and Mississippi River basins that function to prevent the spread of aquatic invasive species (Rasmussen et al. 2011). There is no evidence that suggests that Cyprinella whipplei is capable of hitchhiking or fouling ships. There are no records of the stocking, culture, or sale of Cyprinella whipplei in the Great Lakes region.

Status: Established in Oklahoma.  Cyprinella whipplei is established in Oklahoma (Fuller and Nico 2014). A survey conducted by Fisher et al. (1998) in 1994 found that the historically uncommon Cyprinella whipplei had expanded its range in Tippecanoe County, Indiana since the mid-1970’s. The 1978 survey collected 2 specimens of Cyprinella whipplei, and the 1994 survey collected 16 specimens; however, the authors note that the historically low abundance of Cyprinella whipplei could be attributed to misidentification of this species during the 1978 survey.  Although historically present in Indiana, Cyprinella whipplei was first recorded in the Kankakee River drainage in 1990 (Simon 1992). Cyprinella whipplei was found in fish surveys conducted in 2008 in Killbuck Creek and Pipe Creek, but were absent in 1978 (Doll 2010).

Cyprinella whipplei has a moderate probability of establishment if introduced to the Great Lakes (Confidence level: Moderate).

Cyprinella whipplei has a wide temperature tolerance, and has been reported to occur in streams with temperatures as low as -0.5°C (Felley and Hill 1983) to temperatures as high as 25°C (Risch 2004). This species is somewhat likely to overwinter in the Great Lakes region due to its ability to tolerate low temperature waters and its current geographical range that extends to Illinois and Ohio. It is native to the Alabama and Louisiana, so warmer water temperatures and shorter ice cover may aid the establishment of Cyprinella whipplei. It inhabits streams of varying sizes with sand or gravel bottoms and permanent flows (Ross 2001). This species’ reproductive behavior involves the use of crevices in submerged logs (Pflieger 1965). These habitats are available in the Great Lakes basin.

Cyprinella whipplei may have a low tolerance to habitat degradation. This species once occurred throughout central Illinois, but has retreated eastwards (Smith 2002). Its retreated distribution has been attributed to increasing siltation, removal of riparian vegetation, and the deterioration of water quality, as well as its inability to compete with the red shiner and spotfin shiner. 

Cyprinella whipplei was found in fish surveys conducted in 2008 in Killbuck Creek and Pipe Creek, Indiana, but were absent in 1978 (Doll 2010). Since the 1978 survey, there has been an effort to increase the area of wetland coverage in Indiana, although there has been some clear cutting of the riparian zone in 1998. It is possible that Cyprinella whipplei was able to establish in these areas since 1978 due to increased habitat quality.

Cyprinella whipplei feeds on macroinvertebrates such as aquatic and terrestrial insects, benthic invertebrates, crustaceans, mites, and earthworms (Ross 2001, Stauffer 2007). Its prey is readily available in the Great Lakes basin. Piscivorous animals such as gar, bass, sunfish, sturgeon, large chubs, kingfisher, heron, and turtles are known to feed on shiners (Mayden pers. comm. 2013). These piscivores occur in the Great Lakes region (DEQ-MI 2008). 


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.

Remarks: Smith-Vaniz (1968) reported that a few collections were known from the upper Black Warrior River system (Mobile Bay drainage) of Alabama, and attributed its occurrence to introductions by anglers. However, Barclay and Howell (1973) argued that stream capture rather than bait bucket introductions may have been the source of invasion. Page and Burr (1991) apparently considered the Black Warrior River system to be part of the species' native range.
