Resumo

The occurrence of copepods ergasilid was investigated in two species of cichlids of economic importance for aquaculture in the Amazon region: Cichla monoculus and Chaetobranchus semifasciatus. The fish were collected from a semi-intensive fish farm, near the city of Nauta, Loreto State, Peru. Copepods were found in the gill filaments of 44 of 85 specimens (51.7%) of C. monoculus and in eight of 30 (26.6%) specimens of C. semifasciatus. The parasite was identified as Ergasilus coatiarus based on its morphological features. The occurrence did not vary significantly with host size (P >= 0.05) in both species. This is the first report of E. coatiarus parasitizing C. semifasciatus in the Amazon basin and the first report in C. monoculus from Peru. The high occurrence of these copepods in the present study points out the need of improving the strategies of parasitic prevention and control in order to better prevent future disease outbreaks.
