Abstract
ABSTRACr.-A survey of the White River, Utah, was made during the summer of 1978 and 1979 to determine the abundance and distribution of endemic fishes during and after spring runoff. The fish population was similar to that in other eastern Utah streams. Red shiners (Notropis lutrensis) were most abundant, followed, in order, by roundtail chubs (Gila robusta), flannelmouth suckers (Catostomus latipinnis), speckled dace (Rhinichthys osculus), fathead minnows (Pimephales promelas), carp (Cyprinus carpio), and channel catfish (Ictalurus punctatus). Bluehead suckers (Catostomus discobolus), black bullheads (Ictalurus melas), green sunfish (Lepomis cyanellus), brown trout (Salmo trutta), and Colorado squawfish (Ptychocheilus lucius) individually comprised less than 0.5% of the total number of fish. Native fishes dominated the fish fauna at upstream stations; introduced fishes dominated at downstream stations. A total of 15 adult Colorado squawfish, an endangered fish, was captured or observed.
