In the Neotropical regions, there are an estimated 9,100 species of fish, and all new species are annual, which the Amazon basin is home to about 2,200 species of fish corresponding to this estimate. Leporinus friderici is a fish of the order Characiformes popularly known as 'piau três pintas' or 'aracú', it is an abundant species in the Neotropical regions, which has omnivorous eating habits, feeding on plant material, debris, fruits, seeds, shrimp and small fish. It is a fish widely used in food for the quality of its meat and is easily found in the Rio Matapí-AP region. Quarterly collections were carried out during September 2015 to May 2016 and from August 2017 to October 2018, where 49 specimens of L. friderici were captured. The fauna of L. friderici was quite diverse, being composed of macro and microparasites, infecting gills, intestine, liver, gallbladder, heart, fin and spleen of the host. During the analysis, four taxa were found, namely: Nematoda, Platyhelminthes, Cnidaria (Myxozoa) and Ciliophora, and nine groups of parasites, Anisakidae gen. sp., Contracaecum sp., Dactylogyridae gen. sp., digenea larvae (metacercaria), Henneguya sp., Myxobolus sp., Ceratomyxa sp., Piscinoodinium pillulare, Ichthyophthirius multifiliis, Trichodina sp. and Chilodonella sp .. The occurrence of eukaryotic micropasites was the first recorded for L. friderici from the state of Amapá.
