Observations on the biology of Ergasilus spp. (Cyclopoidea: Copepoda) infesting North American freshwater fishes
Keyword(s):
The gills of 118 yellow perch, Perca flavescens; 18 pumpkinseed, Lepomis gibbosus; 14 rock bass, Ambloplites rupestris; and 15 smallmouth bass, Micropterus dolomieui, were examined for Ergasilus spp. Ergasilus caeruleus was recovered for pumpkinseed and E. confusus from yellow perch. Rock bass and smallmouth bass were infested with E. centrarchidarum and one immature specimen of this species was recovered from a pumpkinseed. The host preference of each parasite species is discussed. A relationship between the egg number of copepods with more than one host and the degree of host preference is suggested.
