Abstract

Fifty specimens of acar・Geophagus brasiliensis (Quoy and Gaimard, 1824) from Guandu River, (22ｰ48’32”S, 43ｺ37’35”W), Rio de Janeiro State, Brazil were studied for their metazoan parasites during December 2004 and November 2005. A total of nine species of metazoan parasites were collected. Posthodiplostomum macrocotyle Dubois, 1937 (metacercariae) found in the eyes, was the most prevalent species (88%) with the highest mean intensity value (12.4), followed by the metacercariae of Austrodiplostomum compactum (Lutz, 1928) and the hirudinean Glossiphoniidae gen. sp. showing prevalence of 14% and 10%, respectively. No parasite species showed significant correlation between the total body length of the host and their prevalence. Posthodiplostomum macrocotyle showed significant correlation between the total body length of the host and their abundance. The sex of the hosts influenced the abundance of P. macrocotyle, A. compactum and Glossiphoniidae gen. sp. being the females the most parasited. The parasite species’ richness showed a mean value of 1.24ｱ0.69 (0-3). The parasite species showed an aggregated distribution pattern.
