First report of Linguadactyloides brinkmanni (Monogenoidea: Linguadactyloidinae) on hybrids of Colossoma macropomum x Piaractus brachypomus (Characidae) from South America. Repositório Alice
DIAS, M. K. R.; TAVARES-DIAS, M.; MARCHIORI, N..
This study presents the first report of infection by Linguadactyloides brinkmanni Thatcher & Krytsky, 1983 (Monogenoidea, Dactylogyridae, Linguadactyloidinae) on the gills of hybrid tambatinga (Colossoma macropomum x Piaractus brachypomus) from fish farms from the city of Macapá, state of Amapá, Brazil. Out of 201 hybrid tambatinga examined, ten were infected by L. brinkmanni (prevalence= 4.9%). From these hosts, 21 specimens of L. brinkmanni were collected and the mean intensity of infection was 2.1 (1-4 parasites/host). This study expands the distribution of this monogenoidean for a new host.

Helminth parasites in two populations of Astronotus ocellatus (Cichliformes: Cichlidae) from the eastern Amazon, Northern Brazil. Repositório Alice
PINHEIRO, R. H. da S.; TAVARES-DIAS, M.; GIESE, E. G..
This study compared the structure of helminth parasite communities in two populations of Astronotus ocellatus from two localities in Pará State, eastern Amazon (Brazil). Hosts from the Tapajós River were infected by Posthodiplostomum sp. metacercarie, larvae of Contracaecum sp. and Pseudoproleptus sp., with predominance of Contracaecum sp. Hosts from Iara Lake were infected by Procamallanus spiculastriatus, Proteocephalus sp. and Acanthocephala gen. sp., with predominance of P. spiculastriatus. Parasites had an aggregated dispersion and there were differences in Shannon diversity index and the evenness between both host populations, because the parasite component community showed no similarity.

The parasitofauna in the giant Amazon basin, pirarucu (Arapaima gigas Schinz, 1822) cultured in fish farms from the state of Amapá, in eastern Amazonia (Brazil) was investigated. Of the 100 examined fish, 90.0% were parasitized by Ichthyophthirius multifiliis (Ciliophora), Dawestrema cycloancistrium, Dawestrema cycloancistrioides (Monogenoidea) and Polyacanthorhynchus macrorhynchus (Acanthocephala), which had an aggregated distribution pattern. The highest infection rates were caused by I. multifiliis and the lowest by P. macrorhynchus. Infection rates were different for each fish farm, due to different water quality and management characteristics. A negative correlation was found between the intensity of monogenoideans D. cycloancistrium and D....
