Common Name: weed shiner
Taxonomy: available through 
Identification: Becker (1983); Page and Burr (1991); Etnier and Starnes (1993); Pflieger (1997).
Size: 8.6 cm.
Native Range: Lowlands in Great Lakes, Hudson Bay (Red River), and Mississippi River basins from Michigan, Wisconsin, and Minnesota south to Gulf; Gulf Slope drainages from Suwannee River, Georgia and Florida, to Nueces River, Texas (Page and Burr 1991).
Nonindigenous Occurrences: This species is known from Second Creek, Lauderdale County, Alabama, near Pickwick Lake in the Tennessee River drainage (Mettee et al. 1996); the upper Ocmulgee River system (Altamaha River drainage, Atlantic Slope) in Georgia (Bart et al. 1994), and Robinson Creek (Pickwick Lake-Tennessee River drainage) in Hardin County, Tennessee (Etnier and Starnes 1993).
Means of Introduction: According to Bart et al. (1994), this species may have entered the Ocmulgee River by stream capture from the Flint River, or as an introduction via bait bucket release. These authors noted that Ocmulgee specimens exhibit the same unique features (deep bodies and higher numbers of body circumferential scales) as do Flint River specimens. Georgia Department of Natural Resources personnel found the species in the Ocmulgee system during 1988-1990 fish survey work. Bart et al. (1994) speculated that it appeared in the Ocmulgee system after construction of the High Falls dam because the species is apparently restricted to the area above the reservoir. The dam was completed in the early 1900s. Notropis texanus apparently invaded the Tennessee drainage from the Mobile basin by way of a canal connection, the Tennessee-Tombigbee Waterway (Etnier and Starnes 1993).
Status: Established in Alabama, Georgia, and Tennessee.
Impact of Introduction: Unknown. According to Etnier and Starnes (1993), range expansion of Notropis texanus in Tennessee would bring it into potential contact with the very similar bigeye shiner N. boops.
Remarks: Samples from the Ocmulgee system, Georgia, represent the first record of this species from the Atlantic Slope (Bart et al. 1994). Mettee et al. (1996), in reference to Etnier and Starnes (1993), mentioned the possible introduction of this species into the Tennessee River drainage via the Tennessee-Tombigbee Waterway. However, in their summary table on Alabama fishes, Mettee et al. (1996) listed it as native to the Tennessee drainage.
