STROMBERG, PAUL C. AND CRITES, JOHN L. An Analysis of the Changes in the Prevalence of Camallanus oxycephalus (Nematoda: Camallanidae) in Western Lake Erie. Ohio J. Sci. 75(1): 1, 1975. Distribution of Camallanus oxycephalus was studied in 16 species of fishes in western Lake Erie during the summer and autumn of 1972. This study was compared to studies done in 1927 and 1957. Analysis of the frequency of infection in these fishes indicates that Camallanus has become more abundant in the lake. This increase has occurred since 1957. The increase in prevalence appears related to changes in plankton, benthos and fish communities of the western basin. The importance of hostparasite contact frequency and its relation to parasite population density and regulation is discussed.
