A Survey Of Monogenetic Trematodes From The Gills Of Salmo Gairdneri, Salvelinus Fontinalis, And Salmo Trutta In Watauga County, North Carolina

Gyrodactylus salmonis (Yin and Sproston, 1948), and Gyrodactylus colemanensis (Mizelle and Kritsky, 1967) were found on the gills of salmo gairdneri (Richardson), and Salvelinus fontinalis (Mitchell, 1815), in Watauga County, NC. This is the first report of these species of Gyrodactylus in North Carolina. Examination of Salmo trutta L. (1758), revealed no parasites on the gills. Host specificity was not observed.
