Abstract

One hundred and twenty-four specimens of Corydoras paleatus (Jenyns, 1842) collected from July 2001 to December 2002 in five reservoirs in Paraná state were analyzed. One hundred and ninety-eight Procamallanus (Spirocamallanus) pintoi (Kohn; Fernandes, 1988) were collected, representing a prevalence of 78.23% and a mean intensity of infection of 2.04 parasites by fish. The values of prevalence and mean intensity of infection for P. (S.) pintoi were submitted to statistical tests for the analysis of the host’s relation. Data showed that the standard length and host’s sex do not influence the parasitism level. Moreover, no significant difference of parasitism among the five analyzed reservoirs was found and the parasitism does not have seasonality
