Metazoan parasite infection in pale chub, Zacco platypus, were investigated from the Yangsan creek in Kyongsangnam-do, Korea, in relation to stream pollution. Pale chubs were collected from the upper and down stream sections in the spring and fall of 1997 where the upper section was preserved for drinking water and the down section was industrialized with many factories. As a result, six species of metazoan parasites were identified; the prevalence and abundance of parasites in fishes were significantly higher in the preserved section; and relatively more parasite species were infected per an individual fish in the preserved section. Status of parasite infection were regarded closely related to environmental pollution, and in particular digenean parasites, Neoplagioporus zacconis and Metagonimus miyatai, whose number of individuals were greatly decreased in the industrialized section, were suggested as useful biological indicators.
