This study evaluated the ectoparasite distribution on the gill archs of pond-reared pacu (Piaractus mesopotamicusHolmberg, 1887), hybrid patinga (P. mesopotamicusfemale x P. brachypomus(Cuvier, 1817) male), hybrid tambacu (Colossoma macropomum(Cuvier, 1816) female x P. mesopotamicus male) and hybrid surubim (Pseudoplatystoma reticulatumfemale x P. corruscansSpix & Agassiz, 1829 male). Atotal of 300 fish were examined from fish farms in West-Central Brazil for parasitological assessment of the gill arches I, II, III and IV, from the outer to inner arch, respectively. Only the monogenean Mymarothecium boegeriCohen & Kohn, 2005 and Anacanthorus penilabiatusBoeger, Husak & Martins, 1995 from the hybrid patinga showed the greatest (p<0.05) mean intensities on the gill arch I when compared to gill arch IV. Microhabitat preference was not observed in the other fish examined. Copepodids of Lernaea cyprinaceaLinnaeus 1758 showed no microhabitat preference. This study highlighted the fact that under culture conditions, homogeneous distribution of parasites on the gills may occur.
