Host and seasonal associations of Acanthocephalus parksidei Amin, 1974 (Acanthocephala: Echinorhynchidae) in Wisconsin fishes.
Ecological associations of Acanthocephalus parksidei Amin, 1974, were studied in 11 southeastern Wisconsin fishes during 1972-73. Parasitic load was found to be related to host species, size (age), sex, concurrent infections, collection site, and season. Distribution in host intestine was related to the extent or intensity of infection, posterior migration, and concurrent infections. Parasitic cycle commenced in later summer-early autumn, peaked (in frequency and maturation) during the spring, and terminated in the  late summer.
