lobatum), larval/immature digenetic trematodes (Neascus rhinichthys), monogeneans
(Cleidodiscus brachus, Dactylogyrus anchoratus, D. extensus, D. vastator, Pseudocolpenteron
pavlovskii), adult cestodes (Khawia iowensis), and adult nematodes (Skrjabinocapillaria bakeri).
Parasites only found in catostomids were protozoans (Trypanoplasma catostomi, Myxobolus
bibullatum, M. conspicuous, M. rotundum), adult digenetic trematodes (Lissorchis attenuatus,
Phyllodistomum lysteri), monogeneans (Acolpenteron catostomi, Anonchohaptor anomalus, A.
muelleri, Cleidodiscus pricei, Dactylogyrus urus, Gyrodactylus spathulatus, Icelanonchohaptor
fyviei, I. microcotyle, Neodiscocotyle carpioditis, Octomacrum lanceatum, Pellucidhaptor
angularis, P. eremitus, P. microcanthus, Pseudomurraytrema copulatum, P. moxostomi), adult
cestodes (Biacetabalum sp., Glaridacris catostomi, Hypocaryophyllaeus paratarius, Spartoides
wardi), adult nematodes (Camallanus ancylodirus, Philometroides nodulosa, Rhabdochona
milleri, R. ovifilamenta), larval nematodes (Philonema sp.); adult acanthocephalans
(Neoechinorhynchus carpiodi, N. crassus, N. cristatus, Octospinifer macilentus), and leeches
(Actinobdella inequiannulata). Parasites only found in percids were protozoans (Trichodina
urinaria, Henneguya doori, Myxobolus scleroperca), adult digenetic trematodes (Allocreadium
boleosomi, Bunodera sacculata, B. lucioperca, Prosorhynchoides pusilla), larval digenetic
trematodes (Apophallus brevis, Tylodelphys scheuringi), monogeneans (Aethycteron malleus,
Urocleidus aculeatus, U. adspectus), adult cestodes (Bothriocephalus formosus, Triaenophorus
stizostedionis), larval/immature nematodes (Hysterothylacium brachyurum, Raphidascaris acus),
and copepods (Ergasilus luciopercarum). Parasites only found in salmonids were adult cestodes
(Proteocephalus exiguus, P. wickliffi), larval cestodes (Diphyllobothrium laruei, Eubothrium
crassum, Schistocephalus sp.), adult nematodes (Cystidicola stigmatura, Cystidicoloides
ephemeridarum), and adult acanthocephalans (Neoechinorhynchus tumidus).
The parasite taxonomic groups, by numbers and percentages, for each of the five major fish
families from Lake Erie are in Table 22. The parasite group(s) (in parentheses) most common in
each fish family were: Cyprinidae (digenetic trematodes followed by myxozoans), Catostomidae
(monogeneans followed by digenetic trematodes), Centrarchidae (digenetic trematodes and
monogeneans), Percidae (digenetic trematodes followed by cestodes), and Salmonidae (cestodes
followed by digenetic trematodes).
The numbers and percentages of autogenic and allogenic helminth species (in parentheses) for
each fish family, respectively, were Centrarchidae (32 species, 76%; 10 species, 24%),
Cyprinidae (17 species, 71%; 7 species, 29%), Catostomidae (22 species, 76%; 7 species, 24%),
Percidae (37 species; 77%, 11 species, 23%), and Salmonidae (7 species, 64%; 4 species, 36%).
Jaccard Coefficients of Parasite Communities—Fish Families
The fish families and the species (in parentheses) involved in calculating Jaccard coefficients of
parasite-community similarity were Centrarchidae (Ambloplites rupestris, Lepomis cyanellus, L.
gibbosus, L. humilis, L. macrochirus, L. megalotis, Micropterus dolomieu, M. salmoides,
Pomoxis annularis, P. nigromaculatus), Cyprinidae (Campostoma anomalum, Carassius auratus,
Cyprinella spiloptera, C. whipplei, Cyprinus carpio, Luxilus cornutus, Lythrurus umbratilis,
Macrhybopsis storeriana, Nocomis micropogon, Notemigonus crysoleucas, Notropis anogenus,
