Project: Initial Survey of the Present Distribution of Myxobolus cerebralis in Yellowstone Cutthroat Trout, Onchorynchus clarki bouvieri, in Yellowstone Lake and Surrounding Tributaries

Primary Investigator: Daniel Mahony
Project Summary: This study marks the beginning of an effort to define the spatial distribution and infection severity of whirling disease in Yellowstone cutthroat trout in Yellowstone Lake, the lake's tributary streams and portions of the Yellowstone River downstream from the lake. Since this subspecies is already seriously threatened by the introduced lake trout, any detrimental effects of whirling disease are of great concern. Three groups of fish from the lake and several tributaries were assayed. The disease was found in older fish throughout the lake, suggesting that it has been present for several years, and that some proportion of young trout can survive infection.
