Abstract

OLIVEIRA, Marcos Sidney Brito de et al. Ectoparasites community in Satanoperca jurupari (Cichlidae) from the Jari River, a tributary from Amazon River in Northern Brazil. Rev. Bras. Parasitol. Vet. [online]. 2017, vol.26, n.2, pp.136-142. ISSN 0103-846X.  https://doi.org/10.1590/s1984-29612017028.

The aim of this study was to investigate the gills parasites in Satanoperca jurupari from the Jari River, state of Amapá, in eastern Amazon (Brazil). The gills of 100% of the hosts were parasitized by Ichthyophthirius multifiliis (Protozoa), Sciadicleithrum juruparii (Monogenoidea) Genarchella genarchella, Posthodiplostomum sp. (Digenea) Ergasilus coatiarus and Argulus multicolor (Crustacea), and a total of 27,043 parasites were collected. However, the dominance was of I. multifiliis and there was aggregated dispersion of parasites with greater discrepancy for S. juruparii and A. multicolor. Low species richness of parasites (3.1 ± 1.1), low Brillouin diversity index (0.27 ± 0.23), low evenness (0.16 ± 0.13) and high dominance of Berger-Parker (0.88 ± 0.15) were found. The community of parasites in S. jurupari was characterized by low species richness, low diversity and low evenness, with high prevalence and low abundance. The size of host did not have any influence on the parasites community, but the host behavior and availability of infective stages of the parasites were factors structuring the community of ectoparasites found here.
