in the spring and early summer at lower elevations and during mid- and late summer in colder waters (Sigler and Miller, 1963). Adults reach a length of 16 in (43 cm) but are more commonly found in the 6 in (15 cm) to 10 in (26 cm) size range (McDonald and Dotson, 1960). Only 44 bluehead suckers, 2.5 cm to 15 cm in length, were found during the survey. Too few were found to make any observations on habitat preferences in the White River. CONCLUSIONS The ichthyofauna of the White River is similar to other rivers in eastern Utah. Red shiners were the most commonly found species (66.1%) followed by roundtail chubs (10.5%), flannelmouth suckers (8.3%), speckled dace (6.6%), fathead minnows (4.1%), carp (3.2%), and channel catfish (.7%). Bluehead suckers, black bullheads, green sunfish, and brown trout individually comprised less then 5% of the total number of fish collected. Endemic fish in the lower sections of the White River have been displaced by exotic fish, a pattern similar to that found in other western rivers and streams. Native fish dominated the fish fauna at 3 stations in the upper part of the White River and exotic fish dominated the fauna at one station in the upper part of the White River and all middle and lower stations. One individual of the humpback-bonytail chub complex was collected at the mouth of the White River. Six adult squawfish were also captured and at least seven observed in the lower 12.2 mi (19.6 km) of the White River during this study. This is the first report of squawfish in the Utah portion of the White River and represents an extension of their known distribution. Extensive sampling of larval and juvenile squawfish habitat was conducted but no fish were found suggesting that the upper 42 mi (76 km) of the White River is not an important squawfish spawning area. The presence of adults in the lower section of the White River does suggest that squawfish utilize major tributaries to the Green River at least some of the time. The presence of Colorado squaw- fish in the lower reaches of the river supports the U. S. Fish and Wildlife's evaluation of White River as "Value Class I: Highest-valued fishery resource".
