The Texas Shiner (Notropis amabilis) is a freshwater ray-finned fish in the Cyprinidae family of the Notropis genus. Native to the United States from Texas to Mexico. Extinct from New Mexico where it was abundant. Closely related to the Red Shiner, Golden Shiner and Blacktail Shiner.
Description of the Texas Shiner
Have a deep, compressed body with a moderately pointed snout and a terminal and oblique mouth.
While, featuring a complete lateral line with large eyes, black lips and a clear stripe just above a black stripe along their sides. However, the stripe is most distinct close to the tail.
While, the dorsal fin is triangular. Meanwhile, the anal fin has 6 – 8 soft rays and the dorsal fin has 10 soft rays.
The Texas Shiner inhabits springs and headwater tributaries. While, limited numbers may occur in larger streams. Meanwhile, some species may inhabit flowing pools and deep river but avoid shallow high-velocity riffles and lentic backwater areas.
While, being abundant in deep pools and silt substrates in fall and deeper pools and runs in fall and winter. Generally, prefer clear water with sand, gravel or rubble substrates. Some populations occur in moderately large schools in streams with moderately fast currents or in upstream ends of pools below riffle areas in swift moving waters along gravel bars and in moderately flowing pools.
Further, found in areas below lower water dams and road crossing with turbulent waters. Meanwhile, they are rarely found in upstream portions of tributary creeks. However, they are dependent on currents often swimming near the surface in eddies created by upstream obstructions and in dense schools of swift moving waters.
Able to adapt to a flood prone existence, shifting between channels and pools in riffles or riffle-like habitats. Generally, habitats include rocky or sandy runs or pools.
Native to the Colorado river to Rio Grande drainage, from Texas and Mexico. As well as, Rio Salado and Rio San Juan in Mexico to the Lower Pecos River in Texas. Primarily found in Edward Plateau from the San Gabriel River in the east to the Pecos River in the west. While, in Mexico the Texas Shiner occurs from the Rio Grande tributaries to the Rio Salado and Rio San Juan.
