Abstract

Fifteen specimens of Piaractus mesopotamicus (pacu), measuring 15 cm standard length, were collected from a fishpond at Aquaculture Center of Unesp, Jaboticabal, SP, Brazil. Fishes were maintained in 350 L aquariums for a further sacrifice with MS-222. For the Scanning Electron Microscopy, gill filaments were fixed in 3% glutaraldehyde. Specimens of Trichodina sp (Ciliophora), Henneguya piaractus (Myxozoa) and Anacanthorus penilabiatus (Monogenea) attacking on the gill epithelium were observed. In the present paper, the external morphology of parasites and the alterations in the gill epithelium of parasitized fishes were reported
