Parasite Species—Overview
LAKE ERIE
Results
A total of 69 studies were found that reported a parasite species infecting one or more fish species
from Lake Erie. These studies were conducted during 1914-2010, and the most studies by 10-yr
period were done in 1970-1979 (Table 4). A total of 229 parasite species (1 Mastigophora, 5
Ciliophora, 22 Myxozoa, 2 Microspora, 46 adult Digenea, 13 larval/immature Digenea, 1
Aspidobothrea, 55 Monogenea, 24 adult Cestoda, 3 larval/immature Cestoda, 21 adult Nematoda,
4 larval/immature Nematoda, 14 adult Acanthocephala, 6 Hirudinea, 13 Copepoda, 1 Mollusca)
have been found in Lake Erie fish (Table 2). Although Allocreadium sp., Crepidostomum sp.,
Leuceruthrus sp., Proterometra sp., Bucephalus elegans, Allacanthochasmus varius, Neochasmus
umbellus, Sanguinicola sp., Centrovarium lobotes, Macroderoides sp., Eubothrium crassum,
Bothriocephalus cuspidatus, Proteocephalus ambloplitis, P. pearsei, P. pinguis, P. stizostethi,
Triaenophorus nodulosus, T. stizostedionis, Hysterothylacium brachyurum, Raphidascaris acus,
Camallanus oxycephalus, Philometra cylindracea, Rhabdochona sp., Acanthocephalus dirus,
Neoechinorhynchus cylindratus, Neoechinorhynchus sp., Leptorhynchoides thecatus, and
Pomphorhynchus bulbocolli were represented in both adult and larval/immature groups, they are
included in the adult category and only counted once. The parasites by taxonomic group and
family, infecting fish from Lake Erie, are listed in Table 20.
Protozoans
Only one species of mastigophoran (Trypanoplasma catostomi) was found in one fish species,
Catostomus commersonii. Four species of ciliates (Ichthyophthirius multifiliis, Trichodina
domerguei, Trichodina urinaria, Capriniana piscium) occurred on the fins, gills and external
surface of fish, except for T. urinaria in the ureters. Ichthyophthirius multifiliis infected 13 fish
species.
Twenty-two species of myxozoans in three families were found. Five species of Henneguya and
13 species of Myxobolus in the Myxobolidae have been documented. Many species, such as
Henneguya doori, Henneguya rupestris, Myxobolus rotundum, are host specific to only one fish
species or to a fish family such as Henneguya exilis and Myxobolus osburni. Unidentified
myxosporans have been found in 38 fish species. All myxozoans occurred in non-intestinal sites.
Only two species of microsporans were found–Glugea cepedianae is host specific to Dorosoma
cepedianum and Glugea hertwigi to Osmerus mordax.
