Trout with “blacktail” associated with whirling disease
Whirling disease, caused by the myxosporean parasite Myxobolus cerebralis was identified as an emerging pathogen of trout in the intermountain west region of the U.S. in the early 1990’s. Investigators here worked collaboratively with others to further our understanding of this disease and its impacts on trout and other salmonid fishes.
