For this reason, theaim of this study was to investigate the parasites in Colossoma macropomum, Arapaimagigas, hybrid tambacu (C. macropomum Cuvier, 1818 x Piaractus mesopotamicus), hybridtambatinga (C. macropomum x Piaractus brachyopomus) and Orechromis niloticus. Thesefish collected from 10 fish farms in Macapá, State of Amapá (Brazil) were necropsied forparasites study. For C. macropomum (n=473) the prevalence of parasitic infection was90.5% (Ichthyophthirius multifiliis, Piscinoodinium pillulare, Anacanthorus spatulatus,Linguadactyloides brinkmanni, Notozothecium janauachensis, Mymarothecium boegeri,Linguadactyloides brinkmanni, Perulernea gamitanea, Braga patagonica e ProcamallanusInopinatus), for A. gigas (n=100) was 95.0% (I. multifiliis, Dawestrema cycloancistrium,Oawestrema cycloancistrioides and Polyacanthorhynchus macrorhynchus), for hybridtambacu (n=121) was 76.0% (I. multifiliis, P. pillulare, A. spatulatus, M. viatorum, N.janauachensis, P. gamitanae, N. buttnerae, Cucullanus colossomi and Proteocephalidealarvae), for hybrid tambatinga (n=483) was 73.5% (I. multifiliis, P. pillulare, Mymarotheciumboegeri, Linguadactyloides brinkmanni, Perulernea gamitanea and P. Inopinatus) and for O.niloticus (n=123) was 64.2% (I. multifiliis, Cichlidogyrus tilapiae, Trichodina sp. andParatrichodina africana). These ectoparasites were found mainly on fish gills, mouth andskin, while few endoparasites were found in intestine of the hosts. Differences in infectionlevels were found in fish of the fish farms studied due to differences in the size and age offish, water quality, management and handling. Therefore, for each fish farm, werecommended the adequate control of parasites and the necessity of handling andmanagement improvements to prevent the spreading of diseases and parasites.Key-words: parasites, freshwater fishEmbrapa project number: 03.09.00.131.00.00162
