A survey of 3–8‐year‐old peamouths Mylocheilus caurinus collected from the lower Fraser River, British Columbia, revealed 100%, infection by a myxosporean identified as Myxobolus cyprini based on spore morphology, site of infection, and associated pathological changes. Myxobolus cyprini is a common myxosporean parasite of several species of cyprinid fishes (family Cyprinidae) in Europe, the former USSR, and China, but this is the first report of this myxosporean in the Western Hemisphere. The source of the infection in peamouths—whether the parasite is endemic to North America or has been imported with exotic cyprinids from Europe or Asia—is unknown. It is also possible that the myxosporean from peamouths is very closely related to, but a distinct species from, M. cyprini of Eurasia. As reported from European cyprinid fishes, the myxosporean in peamouths developed in the skeletal muscle, and disseminated spores were found associated with chronic inflammation in the visceral organs.
