Parasites of Tadpole Madtom, Noturus gyrinus (Mitchill, 1817) (Ictaluridae), from Silver Creek, Michigan, U.S.A., with a Checklist of the North American Parasites of Tadpole Madtom

摘要

Ninety-two tadpole madtom, Noturus gyrinus, collected in May through August 2005 from Silver Creek in Lower Michigan, were examined for parasites. Ten parasite species (5 Digenea, 1 Monogenea, 1 Cestoda, 1 Nematoda, 1 Acanthocephala, and 1 Ciliophora) infected madtom. Macroderoides sp. and Alloglossidium corti had the highest prevalence and mean abundance, respectively. Although Maritreminoides sp. had the highest mean intensity, it is considered an accidental parasite of tadpole madtom. Azygia sp., Macroderoides sp., Maritreminoides sp., and Neoechinorhynchus sp., are reported for the first time from tadpole madtom. This study is the first account of parasites of tadpole madtom from Michigan and represents the largest number of tadpole madtom examined for parasites from one locality in North America. A checklist of parasites of tadpole madtom from published records in North America is also presented.
