Although the three fish species in this study occur in other areas in Oklahoma and the United States (Miller and Robison, 2004), the Arbuckle-Simpson springs provide specialized habitat for two cyprinids, Phoxinus erthyrogaster (southern
redbelly dace) and Nocomis asper (redspot chub) and a percid, Etheostoma microperca (least darter).

Two species and the one hybrid collected by Johnson but not found currently were common shiner (Luxilus cornutus), tadpole madtom (Noturus gyrinus) and northern

Numerous individuals of Campostoma anomalum (central stoneroller), Luxilus cerasinus (crescent shiner) and Phoxinus oreas (mountain
redbelly dace) also schooled over the nest.
Only three fish species occurred in the study reach, Phoxinus erythrogaster (southern
