“…However, life cycle stages of digenean species are generally little-known, limiting knowledge on trematodes infecting fish. The most well documented metacercariae in South American fish belong mainly to the families Diplostomidae, Heterophyidae and Echinostomatidae, which in general use fish-eating birds and aquatic mammals as definitive hosts (Choudhury et al 2016). In this study, metacercariae of Posthodiplostomum sp.…”

Thometrema lotzi is the single species of a genus commonly found in various centrarchid species in the northern Gulf of Mexico drainages (Choudhury et al 2016). However, this study reports Thometrema sp.…”

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.

This study investigated the metazoan parasite fauna in Peckoltia braueri and Pterygoplichthys pardalis from a tributary of the Amazon River system, in northern Brazil. In P. braueri, 630 parasites were collected, belonging to Unilatus unilatus, Nothogyrodactylus sp., Genarchella genarchella, Proteocephalus sp., Gorytocephalus elongorchis, Dolops longicauda and Hirudinea gen. sp., with a dominance of monogenean species. In P. pardalis, 120 parasites were collected, belonging to U. unilatus, Acanthostomum gnerii and Gorytocephalus elongorchis, and this acanthocephalan was the dominant species. In both hosts, the parasites presented clumped distribution, high prevalence, low abundance, low Shannon diversity, and low species richness, with a predominance of helminth species. In P. braueri, host length was positively correlated with parasite species richness and Shannon index. There was no difference in the body condition of parasitized and non-parasitized fishes in either host. This was the first report of these parasites in P. braueri and P. pardalis. KEYWORDS: Digenea, diversity, helminths, parasites, freshwater fishes. Fauna de metazoários parasitando Peckoltia braueri e Pterygoplichthys pardalis (Loricariidae), bagres do nordeste da Amazônia brasileira RESUMOEste estudo investigou a fauna de parasitos metazoários em Peckoltia braueri e Pterygoplichthys pardalis de um tributário do sistema do Rio Amazonas, no Amapá, norte do Brasil. Em P. braueri foram coletados 630 parasitos das espécies Unilatus unilatus, Nothogyrodactylus sp., Genarchella genarchella, Proteocephalus sp., Gorytocephalus elongorchis, Dolops longicauda e Hirudinea gen. sp., com dominância das espécies de monogenoideas. Em P. pardalis foram coletados 120 parasitos das espécies U. unilatus, Acanthostomum gnerii e Gorytocephalus elongorchis, sendo este acantocéfalo a espécie dominante. Os parasitos em ambos hospedeiros apresentaram dispersão agregada, elevada prevalência, baixa abundância, baixa diversidade de Shannon e baixa riqueza de espécies, com predominância de espécies de helmintos. Em P. braueri, o comprimento dos hospedeiros apresentou correlação positiva com a riqueza de espécies de parasitos e o índice de Shannon. Não houve diferença entre a condição corporal de peixes parasitados e não parasitados para os dois hospedeiros. Este foi o primeiro relato desses parasitos para P. braueri e P. pardalis.

Fifty specimens of Cichla piquiti were collected from the Paraná River downstream of the Ilha Solteira Hydroelectric Power Station in Brazil and surveyed for endohelminth parasites. All fish were parasitised by at least one helminth species (overall prevalence [P] = 100%). Eight parasite taxa were present: the nematode Procamallanus (Procamallanus) peraccuratus in the intestines; third-stage larvae of the anisakids Contracaecum sp. and Hysterothylacium sp. in the visceral cavity, mesentery and serosa of the stomach and intestines and on the liver and spleen; the trematodes Austrodiplostomum compactum in the eye (metacercariae) and Genarchella genarchella in the stomach; and the cestodes Proteocephalus macrophallus, Proteocephalus microscopicus, and Sciadocephalus megalodiscus in the intestines. Hysterothylacium sp. larvae (P = 86%) and P. microscopicus (P = 74%) were the most prevalent parasites. Anisakids were more prevalent and abundant in the dry season. A negative correlation between the abundances of Hysterothylacium sp. and P. microscopicus was observed, suggesting a competitive/antagonistic relationship between these parasites. Cichla piquiti represents a new host for four parasite species. These new records significantly increase the list of parasites of C. piquiti, contributing to the knowledge of the host-parasite relationship and the geographical distribution of these helminths.Keywords: New host, introduced fish, peacock bass, Hysterothylacium sp. larvae, Proteocephalus microscopicus. ResumoCinquenta espécimes de Cichla piquiti foram colhidos do Rio Paraná, a jusante da Usina Hidrelétrica de Ilha Solteira, Brasil, na pesquisa de endohelmintos. Todos os peixes estavam parasitados por, pelo menos, uma espécie de helminto (prevalência total [P] = 100%). Foram encontrados oito taxa de parasitas: os nematóides Procamallanus (Procamallanus) peraccuratus no intestino; larvas de terceiro estádio dos anisaquídeos Contracaecum sp. e Hysterothylacium sp. na cavidade abdominal, mesentério e serosa do estômago e do intestino, e sobre o fígado e baço; metacercárias do trematódeo Austrodiplostomum compactum no olho e um indivíduo adulto de Genarchella genarchella no estômago; os cestóides Proteocephalus macrophallus, Proteocephalus microscopicus e Sciadocephalus megalodiscus no intestino. Larvas de Hysterothylacium sp. (P = 86%) e P. microscopicus (P = 74%) foram os parasitas mais prevalentes. Anisaquídeos apresentaram maior prevalência e abundância no período seco. Foi observada uma correlação negativa entre as abundâncias de Hysterothylacium sp. e P. microscopicus, sugerindo uma relação de antagonismo/competição entre esses parasitas. Cichla piquiti é descrito como novo hospedeiro para quatro espécies de parasitas. Estes novos registros aumentam significativamente a lista de parasitas de C. piquiti, contribuindo para o conhecimento da relação parasitohospedeiro e distribuição geográfica desses helmintos.Palavras-chaves: Novo hospedeiro, peixe introduzido, tucunaré, Hysterothylacium sp. larvae, Proteocepha...
