Resumo
In this work are presented data for mean abundance, prevalence and mean intensity of infection in 34 specimens of Pseudoplatystoma fasciatum, commonly called cacharas. Fish were captured using nets in the Aquidauana river during March, September and November 2003, October 2004 and October 2005. All analyzed fish were infected. Nineteen species of parasites were collected - seven of them were proteocephalid cestodes, three monogeneans, one species of digeneans, three nematodes, one acanthocephalan, one crustacean, one pentastomid and two species of myxosporeans. The first records of Harriscolex kaparari and Megathylacus travassosi in P. fasciatum in the Aquidauana river were observed. Monogeneans featured the highest prevalence (100%), followed by cestodes (91.18%) and nematodes (58.82%).
