Dataset Detail
Dataset: Prevalence of infection of fish at acclimation sites
| Project: Relative Susceptibility of Selected Deschutes River, Oregon Salmonid Species to Experimentally Induced Infection by Myxobolus cerebralis
| |
| Dataset Abstract: Prevalence of M. cerebralis infection was measured in sentinel rainbow trout in Spring and Fall 2001 at seven sites in northeastern Oregon where juvenile chinook salmon and steelhead are acclimated. Prevalence of infection was considerably higher at the Wallowa facility than any other facility in the Spring data collection, indicating that this site presents a very high risk for exposure of juvenile steelhead to M. cerebralis as compared with other acclimation sites. | |
| Significance of Results: These data show that M. cerebralis is established in tributaries of the Grande Ronde and Imnaha Rivers and they demonstrate the potential for parasite exposure at all chinook salmon and steelhead acclimation sites. | |
| Relevance to Managers: The Wallowa facility had a high prevalence of infection, indicating that this site presents a very high risk for exposure of juvenile steelhead to M. cerebralis as compared with other acclimation sites. | |
| Questions Generated: Does the incidence of infection measured by sentinel rainbow trout accurately reflect infection in juvenile steelhead or chinook salmon? | |
