Parasite Species
LAKE HURON
Results
Sixty studies have reported on a parasite species infecting one or more fish species from Lake
Huron during 1914-2010 with most studies done after 1960 (Table 4). A total of 242 parasite
species (2 Mastigophora, 5 Ciliophora, 16 Myxozoa, 3 Microspora, 41 adult Digenea, 13
larval/immature Digenea, 69 Monogenea, 23 adult Cestoda, 5 larval/immature Cestoda, 24 adult
Nematoda, 3 larval/immature Nematoda, 16 adult Acanthocephala, 4 Hirudinea, 17 Copepoda, 1
Mollusca) have been reported from Lake Huron fish (Tables 2 and 14). Although Bucephalus sp.,
Centrovarium lobotes, Eubothrium salvelini, Bothriocephalus sp., Cyathocephalus truncatus,
Proteocephalus ambloplitis, P. pearsei, Proteocephalus sp., Triaenophorus crassus, T.
nodulosus, Hysterothylacium brachyurum, Raphidascaris acus, Camallanus oxycephalus,
Capillaria salvelini, Cystidicola sp., Spinitectus gracilis, Philometra sp., Haplonema hamulatum,
Rhabdochona sp., Echinorhynchus salmonis, Neoechinorhynchus tumidus, Pomphorhynchus
bulbocolli, and Leptorhynchoides thecatus were represented in both adult and larval/immature
groups, they are listed in the adult category and only counted once.
Protozoans
Two species of mastigophorans (Trypanoplasma borreli and T. catostomi) have been reported
from one fish species (Catostomus commersonii) from Lake Huron. Five species of ciliates
(Epistylis sp., Ichthyophthirius multifiliis, Trichodina urinaria, Trichodina sp., Capriniana sp.)
were reported in four families of fish. These ciliates occurred on the gills, fins, and skin except
for Trichodina urinaria (ureters). Ichthyophthirius multifiliis infected six fish species.
