The demand for ornamental fish has increased in recent years in Brazil, however, the aquatic environment of artificial breeders facilitates the invasion of pathogens, including parasitic zoonoses, which are a limiting factor for production causing economic losses in creations. Knowledge of the distribution of agents causing parasitic diseases is important so that we can intervene in breeders, therefore, the objective of the present work is to report the occurrence of infection by Eustrongylides sp. (Nematoda: Eustrongylidae) in Polypterus endlicherii (Polypteriformes: Polypteridae) in central Rio Grande do Sul, Brazil. The nematode was identified after being released a cyst in the scales, of a fish of the species P. endlicherii. It can be concluded that this is the first record of the occurrence of Eustrongylides sp. larvae in fish in Rio Grande do Sul, showing that the parasite is present in the central region of the state. Therefore, further studies should be carried out in order to verify the presence of the parasites in fish intended for human consumption. It should also be noted the need to be more careful when feeding fish with oligochaetes, especially those intended for human consumption.
Keywords: aquarism; Saddled bichir; nematode; parasitism.
