Resumo: Monogeneans are ectoparasites of fish with a global distribution. In farmed fish, high infestations may result in morbidity and mortality. This study investigated the histopathological effects of three species of monogeneans Anacanthorus spathulatus, Notozothecium janauachensis and Mymarothecium boegeri on the gills of farmed Colossoma macropomum. Parasitological indices revealed a prevalence of 100%, and a mean abundance of 81.3 ± 11.8. This infection caused displacement of the gill epithelium, focal hyperplasia of epithelial cells, lamellar fusion, congestion and shortening of the secondary lamellae of gills, in addition a complete fusion of the secondary lamellae. However, these tissue alterations were reversible and punctually located lesions, which may not compromise the normal functioning of gills. Lastly, this study showed the potential damages caused by parasite monogeneans to gills of infested fish, thus sanitary management is essential for the growth of fish farm of C. macropomum.

Em peixes de viveiro, altas infestações podem resultar em morbidade e mortalidade. Este estudo investigou os efeitos histopatológicos dos monogeneas Anacanthorus spathulatus, Notozothecium janauachensis e Mymarothecium boegeri. Os índices parasitológicos revelaram uma prevalência de 100% e uma abundância média de 81,3 ± 11,8. Essa infecção causou deslocamento do epitélio branquial, hiperplasia focal das células epiteliais, fusão lamelar, congestão e encurtamento das lamelas secundárias das brânquias, além de uma fusão completa das lamelas secundárias. Porém, essas alterações teciduais são lesões reversíveis e pontuais, que podem não comprometer o funcionamento normal das brânquias. Esses resultados mostram potencial danos de monogeneas nas brânquias dos peixes infestados, assim o manejo sanitário é essencial para o crescimento da piscicultura de C. macropomum.UEL2021-04-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/4046510.5433/1679-0359.2021v42n3Supl1p2057Semina: Ciências Agrárias; Vol. 42 No. 3Supl1 (2021); 2057-2064Semina: Ciências Agrárias; v. 42 n. 3Supl1 (2021); 2057-20641679-03591676-546Xreponame:Semina.
