– The physical habitat utilization of 7 species of native fishes in a Sonoran Desert stream, Aravaipa Creek, Arizona is described. The species occupied significantly different depths and velocities of water. Longfin dace ( Agosia chrysogaster ), speckled dace ( Rhinichthys osculus ) and loach minnow ( Tiaroga cobitis ) used similar depths and velocities. Two of the three larger species (Sonora sucker [ Catostomus insignis ] and roundtail chub [ Gila robusta ]) used areas of greater depth and reduced velocity. Desert sucker ( Catostomus clarki ) grouped with loach minnow and speckled dace in the velocity of water occupied, but utilized deeper waters. The spikedace ( Meda fulgida ) aligned very closely with desert sucker in use of all 3 physical habitat variables.
