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.

Materials and MethodsThe list of parasitic crustaceans of fishes in Brazil was based on extensive search of published records. This bibliographic review of the crustacean species reported from fishes in Brazilian waters was complemented with information from the Zoological Record, Biological Abstracts, Web of Knowledge, Google Scholar, Aquatic Sciences and Fisheries Abstracts, Biological and Agricultural Index Plus and the Scopus. Data were compiled until March, 2013. In the case of parasitic copepods, only information not presented in the checklist of Copepoda parasites of fishes from Brazil by Luque and Tavares (2007) was included. The number of parasitic associations was calculated from the sum of the richness of species of parasites on each host species.The checklist follows the classification and systematic arrangement proposed by Boxshall and Halsey (2004) for Copepoda, and Young (1998) and Martin and Davis (2001) for other crustacean groups.The species of crustaceans are arranged according to taxonomic categories, within which the species are presented in alphabetical order, followed by hosts (specific name), site of infection, habitat, localities and references (between parentheses, in chronological order). In addition, the checklist also includes crustacean species identified only at the genus level and undetermined species. Crustacean names presented in the checklist follow the most recent taxonomic literature, but validity of individual taxa or reliability of their records was not critically examined by the present authors. Host species were arranged in taxonomic and then alphabetical order.The key to identification of the genera of parasitic crustaceans from fishes in Brazil has been produced on the basis of those by Delaney

“…Weight, standard length and gender of the hosts were recorded. Necropsy of the hosts, collection, conservation and preparation of ectoparasites were performed according to the method of Malta (1982a). The standard length (Ls) and total weight (Wt) of each host were adjusted to the Wt/Ls relationship curve (Wt = a.Lt b ), given the estimated values of the regression coefficients a and b.…”

“…However, little information is available on the infestation levels and modes of transmission of crustacean ectoparasites in natural conditions (Szalai & Dick, 1991). Most studies on branchiuran crustacean ectoparasites published in South America are related to taxonomy (Malta, 1982a;Tanaka, 2000). The Branchiura is a small group of ectoparasites, comprising a single family (Argulidae), with only four genera, i.e., Argulus, Dolops, Dipteropeltis, and Chonopeltis.…”
