| Summary: | Most of the 24 parasite species identified from Devils Lake have been identified downstream The exceptions are Epistylis sp. and Gyrporhynchidae which have not been identified downstream of Devils Lake. However a closely related protozoan genera, Caprinia sp., has been identified from fish in the Red River estuary. The leech, Myzobdella lugubris, was not identified from the Red River estuary but the genus is common in the Hudson Bay drainage. The assessment is based on the known distribution of these organisms on both sides of the USA/Canada border and the potential for transfer.
