Abstract
The Moapa River of eastern Clark County, Nevada was surveyed in January 1974 and August 1975 to determine the status of the native fishes. Thirteen species were collected; four are native to the Moapa River. Two nonnative species not previously recorded were collected. The abundance and range of two native species, Moapa coriacea and Gila robusta, decreased since the river was last surveyed (1964–68). A combination of factors likely account for this: habitat modification, poor water quality, and the presence of nonnative fishes.
