Project: Assessment of the Effects of Landscape Features on the Distribution of Myxobolus cerebralis and Occurrence of Whirling Disease among Age-0 Mountain Whitefish in the Salt River Drainage, Wyoming-Idaho

Primary Investigator: Wayne Hubert
Project Summary: Age-0 trout (brown, cutthroat, rainbow, and brook trout) were collected in streams of all sizes throughout the drainage. Trout not infected with whirling disease were only found in the headwaters of four mountain tributaries, all upstream from barriers to fish movement. Disease infection rates and histological evidence of whirling disease were highest at sites with large amounts of fine sediments and low channel slopes. Such sites were found in some spring streams with very low channel slopes, some spring streams with higher channel slopes and habitat improvements that resulted in numerous deep pools with abundant aquatic vegetation, and mountain tributaries downstream from complexes of beaver dams.
