A total of 635 trout (366 rainbow trout, Oncorhynchus mykiss Richardson, 1836; 166 brook trout, Salvelinus fontinalis Mitchill, 1814; 103 brown trout, Salmo trutta Linnaeus, 1758; Salmonidae) collected in March-July 1996, 1997, and 1998 from 12 trout farms in Michigan, U.S.A., was examined for parasites. Twelve parasite species (1 Acanthocephala, Acanthocephalus dirus (Van Cleave, 1931) Van Cleave and Townsend, 1936; 1 Monogenea, Gyrodactylus sp.; 2 Cestoda, Eubothrium salvelini (Schrank, 1790), Proteocephalus sp.; 1 Nematoda, Truttaedacnitis sp.; 1 Copepoda, Salmincola edwardsii (Olsson, 1869); 1 Myxozoa, Myxobolus cerebralis (Hofer 1903); 4 Ciliophora, Capriniana sp. [=Trichophrya sp.], Chilodonella sp., lchthyophthirus multifiliis (Fouquet, 1876), Trichodina sp.; and 1 Mastigophora, lchthyobodo sp. [=Costia sp.]) were found. Rainbow trout were infected with A. dirus, Truttaedacnitis sp., E. salvelini, Proteocephalus sp., Gyrodactylus sp., M. cerebralis, lchthyobodo sp., Capriniana sp., Chilodonella sp., l. multifiliis and Trichodina sp. Brook trout were infected with A. dirus, S. edwardsii, E. salvelini, M. cerebralis, and Trichodina sp. Acanthocephalus dirus was the only parasite infecting brown trout. Eubothrium salvelini, A. dirus, and Trichodina sp. infected trout from 9, 8, and 8 farms, respectively. Acanthocephalus dirus in all trout species and S. edwardsii on brook trout had the highest prevalences, mean intensities, and mean abundances.
