Dataset Detail
Dataset: Prevalence of M. cerebralis infection in rainbow trout
| Project: Distribution and Seasonal Occurrence of Myxobolus cerebralis in the Lostine River, Oregon
| |
| Dataset Abstract: Rainbow trout and chinook salmon fry were placed in sentinel cages in the Lostine River (Oregon) and were naturally exposed to triactinomyxons (TAMs). After exposure, a subsample of rainbow trout fry were sampled by PCR to determine that the parasite was present at the time of exposure. (No chinook salmon fry were sampled at this time due to the limited number of survivors.) | |
| Significance of Results: This data established the presence and infectivity of M. cerebralis earlier in the year (March), when water temperatures are still cool. | |
| Relevance to Managers: These data indicate that rainbow trout can become infected after a brief (14 day) exposure at cooler water temperatures (March). These data indicate that resident juvenile Chinook salmon are liable to be infected during hatch/emigration to the ocean. | |
| Questions Generated: Do juvenile Chinook salmon become infected in the Lostine River? | |
