Description

All text below is derived from a January 2013 copy of Dr. Timothy Bonner's website at Texas State University. That content was derived primarily from published literature. We are aware of some conflicts with the museum record and the content below will evolve as the new, expanded UT and Texas State Fishes of Texas project team members are able to update it. We invite collaborations to improve and expand the species account content. Please contact us if you wish to help, or if you discover flaws in our species account content that you can address.

Type Locality

Lake Ponchartrain, Louisiana (Valenciennes in Cuvier and Valenciennes 1844).

 

Etymology/Derivation of Scientific Name

 

 

Synonymy

Sclerognathus cyprinella Valenciennes in Cuvier and Valenciennes 1844:477.

Ictiobus cyprinella

 

Characters

Maximum size: 100 cm TL (Page and Burr 1991).

 

Coloration:

 

Counts: Fewer than 45 lateral line scales; 22-30 dorsal fin rays (Hubbs et al. 2008).

 

Mouth position: Mouth large and very oblique (Hubbs et al. 2008). Terminal (Goldstein and Simon 1999).

 

Body shape: Eye closer to tip of snout than back of head; head gradually more slender than body; dorsal fin base more than one-third of standard length (Hubbs et al. 2008).

 

External morphology: Upper jaw as long as snout; upper lip about level with the lower margin of orbit; lips thin and faintly striate; subopercle broadest at middle, subsemicircular; cheek shallow and foreshortened (distance from eye to posteroventral angle of preopercle ¾ of distance to upper corner of the gill slit) (Hubbs et al. 2008).

 

Internal morphology: Intestine very long with at least 4 loops (Goldstein and Simon 1999).

 

Distribution (Native and Introduced)

U.S. distribution: Ranges from the Great Lakes southward through the Ohio and Mississippi river basins (Hubbs et al. 2008). Lake Erie drainage south in Ohio and Mississippi drainages to northern Alabama, southern Louisiana, Texas, Oklahoma, and Arkansas, west and north to Minnesota, and Manitoba and Saskatchewan (Canada); introduced in Arizona and California (Lee and Shute 1980).

 

Texas distribution: Limited to the Red River east of Lake Texoma and the Sulphur River in the extreme northeast part of the state (Hubbs et al. 2008).

 

Abundance/Conservation status (Federal, State, NGO)

Currently Stable (Warren et al. 2000) in the southern United States.

 

Habitat Associations

Macrohabitat: Common in shallows of large, sluggish rivers, oxbows, bayous, reservoirs, and lakes (Lee and Shute 1980).

 

Mesohabitat:

 

Biology

Spawning season:

 

Spawning habitat: Spring flooding triggers spawning which occurs in shallow waters at temperatures of 15.5-18.3°C (Lee and Shute 1980).

 

Spawning behavior: Nonguarder; open substratum spawner; lithopelagophil – rock and gravel spawner with pelagic free embryos (Simon 1999). Embryos initially have an adhesive chorion that soon become buoyant eggs; free embryos are pelagic by positive buoyancy or active movement, free embryos have limited embryonic structures, and larvae are unconfirmed nonphotophobic (Balon 1981; Simon 1999).

 

Fecundity

 

Age at maturation

 

Migration:

 

Growth and Population structure: 

 

Longevity:

 

Food habits: Invertivore; main food items for young fish include copepods, cladocerans, chironomid larvae, and diatoms; main food items for older fish include entomostracan, aquatic beetles, mollusks, and amphipods (Goldstein and Simon 1999). Species occupies feeding niche overlapping bottom and limnetic plankton feeders (Minckley et al. 1970).

 

Phylogeny and morphologically similar fishes

Ictiobus cyprinellus hybridizes in nature with the closely related smallmouth buffalo (I. bubalus; Johnson and Minckley 1969); hybrids between I. cyprinellus and the black buffalo (I. niger) have been cultured (Stevenson 1964).
