Diagnosis, prevalence, and prevention of the spread of the parasite Heterosporis sp. (Microsporida: Pleistophoridae) in yellow perch (Perca flavescens) and other freshwater fish in northern Minnesota, Wisconsin, and in Lake Ontario
A previously unknown microsporidian parasite that severely degrades muscle of yellow perch (Perca flavescens) from lakes in Minnesota, Wisconsin, and Lake Ontario was identified as belonging to the genus Heterosporis. This parasite is characterized by pyriform-shaped spores that are contained in spo...
