Abstract

Parasites of 111 specimens of the Gymnotus genus were analyzed. The fishes were captured in bolters and gill nets. Sixteen parasite species were recorded, being 93.7% of the species found in larval stages. Significant positive association and correlation between abundances of twenty pairs of species occurred. All the analyzed parasite species had a clumped pattern in host sample. No dominance was reported among the parasite species. Diversity of the infracommunities of male and female hosts were not different, but influence of hosts' sex in the prevalence and abundance of Tylodelphys sp. and Spiroxys sp. were observed. Significant positive correlation between hosts' total length and prevalence and abundance of Nomimoscolex chubbi, Contracaecum sp. 2 and Quadrigyrus machadoi was observed. The reproductive cycle of hosts was correlated with the Herpetodiplostomum sp. 1, Herpetodiplostomum sp. 3, Neodiplostomum sp. and Tylodelphys sp. prevalences
