| Sumario: | The trahira is a food fish that can harbor parasites that cause zoonoses. In order to inventory the helminths parasitizing Hoplias aff. malabaricus Bloch, 1794 (Actinopterygii: Erythrinidae) from the Araguaia River, Araguanã city, Tocantins, Brazil, 50 specimens captured between January and March 2012 were examined. A total of 36 parasites were detected, collected from the gills, fins, skin, muscles and intestine, recorded in four species: Eustrongylides tubifexNitzsch in Rudolphi, 1819 (Nematoda: Dioctophymatidae); Ithyoclinostomum dimorphumDiesing, 1850 (Digenea: Clinostomidae); Sebekia oxycephala(Diesing) Sambon 1922 (Pentastomida: Sebekidae) and Acantocephala (cystacanthus). Of the infected fish, 17 were infected by only one species, two animals were parasitized by two species and one animal was parasitized by three species. Eustrongylides tubifexwas the most prevalent (60%; N=30) and the most abundant (0.05). The presence of parasites of different taxonomic categories observed in Hopliasaff. malabaricusis important due to the maintenance of the parasites and their cycle in the environment. The present study demonstrated that Hopliasaff. malabaricusfrom the Araguaia River are parasitized by helminths of different taxa. Therefore, it is recommended to carry out a rigorous health assessment regarding parasitic contamination, with the purpose of preventing diseases, since the presence of these parasites can pose a risk to human health. |
