R. aLow levels of crustacean parasite infestation in fish species from the Matapi River in the state of Amapá, Brazil.h[electronic resource] c2019 aShort Communication. aThis first study investigated the crustacean parasite fauna in 66 species of fish from the Matapi River basin, state of Amapá (Brazil). Fish were collected every two months between March 2012 and August 2013, encompassing dry and rainy seasons. Among the 66 species examined (corresponding to 722 fish specimens) only 11 species were parasitized. The infestation prevalence was 2.2%, and a total of 48 specimens of parasites were distributed between three different parasite groups. These included Argulus elongatus, Dolops reperta and Argulus multicolor (Branchiura), Ergasilus xinguensis and Gamidactylus sp. (Copepoda), and Isopoda (Braga patagonica), but branchiuran species were predominant. This was the first report of these parasite species for Leporinus fasciatus, Astyanax bimaculatus, Curimata incompta, Pygocentrus nattereri, Crenicichla cincta, Crenicichla johanna, Geophagus camopiensis, Pterophyllum scalare, Plagioscion squamosissimus, Hypostomus plecostomus and Propimelodus eigenmanni. Lastly, this study expands the range of occurrence of these six parasite species to the Matapi River basin in eastern Amazon. aAmazonia aEctoparasites aFreshwater fish aParasito de Animal aPeixe de Água Doce aInfestation1 aTAVARES-DIAS, M. tBrazilian Journal of Veterinary Parasitologygv. 28, n. 3, p. 493-498, July/Sep. 2019.
