Project: Distribution of Myxobolus cerebralis during the Migration Period for Juvenile Anadromous Salmonids in the Snake and Salmon Rivers of Idaho

Primary Investigator: Ken Cain
Project Summary: This project assessed the distribution, prevalence and intensity of whirling disease infection in sentinel rainbow trout within the migration corridor of anadromous species in the Salmon and Snake Rivers in Idaho. The results show infectivity to be correlated with water chemistry and discharge. Juvenile salmonids emerging or migrating through the upper reaches of the Salmon River in April and May are exposed to the infectious stage of the parasite. A discontinuous pattern of infectivity in the upper Salmon River suggests that the parasite may be present in high concentrations in the Pahsimeroi and Lemhi tributaries, and the detection of the parasite at downriver sites indicates that distribution within the drainage may be expanding.
