ABSTRACT
ABSTRACT This study investigated the parasitic fauna of Cichlasoma bimaculatum of a tributary from the Amazon River system, northern Brazil. The prevalence of infection was 94.6 % and, in total, 428 267 parasites, such as Ichthyophthirius multifiliis, Piscinoodinium pillulare (Protozoa), Gussevia arilla (Monogenoidea), Posthodiplostomum sp. (Digenea) and Procamallanus (Spirocamallanus) inopinatus (Nematoda) were collected. However, the dominance was mainly of I. multifiliis, while P. (S.) inopinatus was the parasite species with the lower levels of prevalence and abundance of infection. These parasite species showed an aggregated dispersion pattern. The parasitic fauna was characterized by the presence of few species of parasites with high prevalence and abundance, specifically ectoparasites, and a low number of endoparasites. The observed pattern is explained by the mode of life of the host and it is suggested that C. bimaculatum occupies a low trophic level at the food web.
RESUMEN
RESUMEN Este estudio investigó la fauna parasitaria de Cichlasoma bimaculatum (Cichlidae) en un afluente del sistema del Río Amazonas, en el norte de Brasil. La prevalencia parasitaria fue del 94,6 % y en total, 428267 parásitos fueron colectados, entre estos Ichthyophthirius multifiliis, Piscinoodinium pillulare (Protozoa), Gussevia arilla (Monogenoidea), Posthodiplostomum sp. (Digena) y Procamallanus (Spirocamallanus) nopinatus (Nematoda). Aunque el predominio fue de I. multifiliis, el nematodo P. (S.) inopinatus fue la especie menos frecuente y abundante. Estas especies de parásitos mostraron un patrón de dispersión agregada. La fauna parasitaria se caracterizó por la presencia de algunas pocas especies de parásitos con mayor prevalencia y abundancia de ectoparásitos y una baja presencia de endoparásitos. Se discute que lo anterior puede deberse al modo de vida del hospedero y sugieren que C. bimaculatum ocupa un bajo nivel en la cadena trófica.
