Resumo: The present work studied the seasonal variation of the metazoan parasites of Geophagus brasiliensis from the Guandu river, State of Rio de Janeiro, Brazil. Four collections of 50 specimens of G. brasiliensis were accomplished between April 2006 and March 2007, in the different seasons. A total of 14 species of metazoan parasites were obtained: six trematodes (Crassicutis sp. in adult stage and five metacercariae, Austrodiplostomum compactum, Diplostomulum sp., Neascus type 1, Neascus type 2 and Posthodiplostomum sp.), three nematodes (Contracaecum sp. larval, Cucullanus sp. and Procamallanus (Procamallanus) peraccuratus adult); monogenean (Sciadicleithrum guanduensis); acanthocephalan (Neoechinorhynchus paraguayensis), larval glochidia; and hirudinean species of Glossiphonidae and Piscicolidae. With the exception of Glossiphonidae hirudinean, all parasite species showed prevalence and abundance peaks mainly in the spring sample, which could indicate seasonality of these parasite species in G. brasiliensis from the Guandu River.

Para isso foram realizadas quatro coletas trimestrais de 50 espécimes de G. brasiliensis entre abril de 2006 e março de 2007, nas diferentes estações do ano. Foram coletadas 14 espécies de metazoários parasitos: seis digenéticos (Crassicutis sp. em estágio adulto, e cinco tipos de metacercárias, Austrodiplostomum compactum, Diplostomulum sp., Neascus tipo 1, Neascus tipo 2 e Posthodiplostomum sp.); três nematóides (larvas de Contracaecum sp., adultos de Cucullanus sp. e Procamallanus (Procamallanus) peraccuratus) ; o monogenético (Sciadicleithrum guanduensis); o acantocéfalo (Neoechinorhynchus paraguayensis); larvas gloquídias de molusco e espécies de hirudíneos das famílias Glossiphonidae e Piscicolidae. Com exceção dos hirudíneos glossifonídeos, todas as espécies apresentaram picos de prevalência e abundância principalmente naqueles peixes coletados na primavera, o que pode indicar uma sazonalidade dessas espécies de parasitos em G. brasiliensis do rio Guandu.Universidade Estadual De Maringá2010-05-24info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciBiolSci/article/view/488310.4025/actascibiolsci.v32i2.4883Acta Scientiarum.
