This paper records the first occurrence of Epistylis sp. on the body surface of Argulus sp. parasitizing Hoplias aimara from the upper Araguari River, in the eastern Amazon region, in the north of Brazil. Of the 16 specimens of H. aimara examined, 93.7% had their pelvic, caudal and pectoral fins and tegument infested by Argulus sp. (n = 73), which in turn were infested by Epistylis sp. The specimens of Epistylis sp. from the body surface of Argulus sp. were analyzed using Scanning Electron Microscopy (SEM). The present study also identified a widening of the geographic distribution of these two species of ectoparasites to the eastern Amazon region of Brazil.

“…The first report of A. pestifer for H. unitaeniatus comprised a low level of gill parasitism, similar to what has been described for Pseudoplatystoma trigrinum in Manaus, state of Amazonas (LOPES et al, 2009). However, this parasitism of A. pestifer was lower than what was described for Pseudoplatystoma fasciatum and P. trigrinum from Janauacá Lake, (MALTA, 1984) and for Pseudoplatystoma punctifer from Manaus region, both in state of Amazonas (LOPES et al, 2009). Thus, A. pestifer is an argulid with low parasitic specificity and it depends on its hosts for geographic dispersion and distribution (MALTA, 1984 Santos-Neto et al (2015).…”

“…On the other hand, H. unitaeniatus has been parasitized by species of crustaceans (MALTA, 1984;LEAL et al, 2010), nematodes (MARTINS et al, 2005;BENIGNO et al, 2012) and acanthocephalans ). However, the structure of the parasite communities and infracommunities of these two hosts has not been studied.…”

This study compared the parasite communities of Hoplias malabaricus and Hoplerythrinus unitaeniatus from Amazon river system. Hoplias malabaricus were infected by Ichthyophthirius multifiliis, Piscinoodinium pillulare, Tetrahymena sp., Urocleidoides eremitus, Braga patagonica, metacercariae of Clinostomum marginatum, Procamallanus (Spirocamallanus) inopinatus, larvae of Contracaecum sp. and larvae of Nomimoscolex matogrossensis. Hoplerythrinus unitaeniatus were also infected by these same species of protozoans, nematodes, digeneans and cestodes, except for Tetrahymena sp. and B. patagonica, which were replaced by Argulus pestifer, Urocleidoides sp., Whittingtonocotyle caetei, Whittingtonocotyle jeju and Gorytocephalus spectabilis. For both hosts, I. multifiliis and P. pillulare were the predominant parasites. Most of the parasites presented an overdispersion. Parasite species richness, Brillouin diversity, evenness and Berger-Parker dominance were similar for the two hosts. The length and weight of H. malabaricus showed a positive correlation with the abundance of U. eremitus and Contracaecum sp., while the weight of H. unitaeniatus showed a positive correlation with the abundance of I. multifiliis. The diversity of ectoparasites seemed to be influenced by the behavior of these two hosts. This was shown by the similar parasite communities and was characterized by low species diversity, low evenness and low richness, and by a high prevalence of ectoparasites.Keywords: Amazon, diversity, Erythrinidae, overdispersion, parasites infracommunity. ResumoEste estudo comparou a comunidade parasitária de Hoplias malabaricus e Hoplerythrinus unitaeniatus do sistema do Rio Amazonas. Hoplias malabaricus estavam infectados por Ichthyophthirius multifiliis, Piscinoodinium pillulare, Tetrahymena sp., Urocleidoides eremitus, Braga patagonica, metacercarias de Clinostomum marginatum, Procamallanus (Spirocamallanus) inopinatus, larvas de Contracaecum sp. e larvas de Nomimoscolex matogrossensis. Hoplerythrinus unitaeniatus estavam também infectados por essas mesmas espécies de protozoários, nematoides, digeneas e cestóide, exceto Tetrahymena sp. e B. patagonica, que foram substituídos por Argulus pestifer, Urocleidoides sp., Whittingtonocotyle caetei, Whittingtonocotyle jeju e Gorytocephalus spectabilis. Para ambos os hospedeiros, a dominância foi de I. multifiliis e P. pillulare. Houve dispersão agregada para a maioria dos parasitos e similar riqueza de espécies de parasitos, diversidade de Brillouin, uniformidade e dominância de Berger-Parker, para ambos os hospedeiros. O comprimento e peso de H. malabaricus mostrou correlação positiva com a abundância de U. eremitus e Contracaecum sp., enquanto o peso de H. unitaeniatus mostrou correlação positiva com abundância de I. multifiliis. A diversidade de ectoparasitos parece influenciada pelo comportamento desses dois hospedeiros. Isso é mostrado pela similar comunidade de parasitos e caracterizada por uma baixa diversidade de espécies, baixa uniformidade e baixa riqueza de esp...

Some composition and structural patterns were here detected in the parasite community of A. ocellatus in the different basins in Brazil, including: (a) dominance of G. asota and Gussevia astronoti Kritsky, Thatcher and Boeger 1989; (b) dominance of ectoparasite species with crustacean infracommunities more diverse than other ectoparasites; (c) overdispersion of ectoparasites and endoparasites, (d) interspecific associations in the ectoparasite infracommunities, specifically a combination of generalist and specialist parasites that should contribute to host population control (e.g.…”

The community composition of parasites was characterized in Astronotus ocellatus from a tributary of the Amazon River, northern Brazil. The prevalence was 87.9%, and a total of 526,052 parasites were collected, with a mean of 15,941 parasites per host. Nine taxa of ecto-and endo-parasites were identified, but Ichthyophthirius multifiliis was the dominant species, while Piscinoodinium pillulare, Clinostomum marginatum and Argulus multicolor were the least prevalent parasites. The parasite community was characterized by a low species richness, low diversity and low evenness. Host body size was not found to influence the composition of the parasite community, and there was no significant correlation between abundance of any parasite species and host body size. Papers published concerning the presence of parasites in this host in different hydrographic basins within Brazil indicate that 22 species of parasites are known to infect A. ocellatus, including species of ectoparasites and endoparasites. In Brazil, ectoparasites species, particularly crustaceans, have been found to parasitize A. ocellatus in relatively high numbers. This predominance of ectoparasites is typical of fish of lentic ecosystems. Finally, the presence of different endoparasites taxa suggest that A. ocellatus acts as an intermediate or definitive host.
