Abstract: In the Amazon, the growing demand for fish has been boosting the expansion of fish farms. However, the intensification of cultivation can generate disequilibrium in the parasite-host environment, predisposing fish to parasitic infections. The objective of this study was to evaluate the community structure of metazoan parasites in cultivation systems of piauçu, Leporinus macrocephalus, in the state of Acre, Brazil. We examined 100 specimens from a semi-intensive cultivation system (earth tanks) and 100 from an … Show more

“…In L. macrocephalus of four fish farms from Rio Branco, State of Acre, the parasitic prevalence was 61.9%. Similar prevalence was reported by Martins et al (2017a) for this same fish cultured in thanks and dam in Cruzeiro do Sul, State of Acre. However, this was higher than the prevalence (21.3%) reported by Martins et al (2002) for L. macrocephalus from fish farms in the State of São Paulo.…”

“…However, in the four fish farms studied, fish did not present macroscopic signals of diseases, due to low to moderate levels of parasitism. In general, the parasitism rate in L. macrocephalus has been attributed to stocking density and poor water quality, which favors the dissemination of infectious stages of parasites (Tavares-Dias et al 2001a, b, Martins et al 2002, 2017a. Also, U. paradoxus, U. eremitus and P. (S.) inopinatus were the parasites with higher prevalence in L. macrocephalus, and they showed a high aggregated dispersion, a pattern also found by Martins et al (2017a) for this same host species.…”

“…According to Moravec (2010), R. (R.) acuminata is the only species of Rhabdochona reported from South America that also could be found in southern Mexico. The species R. (R.) acuminata was reported in Ecuador (Petter 1987), in Argentina (Szidat 1956;Cremonte et al 2002;Ramalho 2005;Ailán Choke et al 2014) and in Brazil (Travassos et al 1928;Vaz and Pereira 1934;Kloss 1966;Kohn and Fernandes 1987;Paraguassú et al 2005;Paraguassú and Luque 2007;Tavernari et al 2009;Costa et al 2011;Abdallah et al 2012;Santos-Clapp and Brasil-Sato 2014;Duarte et al 2016;Ribeiro et al 2016;Martins et al 2017;Yamada et al 2017;Pereira et al 2018).…”
