Three common, commercially important, freshwater fishes were surveyed for their crustacean parasites. A total of 387 roach, Rutilus rutilus, and a total of 370 bream, Abramis brama, were examined from 1985 to 1988. The former carried three parasite species; the latter carried four. In addition a total of 433 pike-perch, Stizostedion lucioperca, was examined during 1984-1988. This fish species hosted four parasite species. Prevalence, intensity (range & mean), and abundance were calculated for each parasite. Attention has been given to seasonal differences in infection, as well as to differences between the three localities sampled.
