          Abstract

          Abstract This first study investigated the crustacean parasite fauna in 66 species of fish from the Matapi River basin, state of Amapá (Brazil). Fish were collected every two months between March 2012 and August 2013, encompassing dry and rainy seasons. Among the 66 species examined (corresponding to 722 fish specimens) only 11 species were parasitized. The infestation prevalence was 2.2%, and a total of 48 specimens of parasites were distributed between three different parasite groups. These included Argulus elongatus, Dolops reperta and Argulus multicolor (Branchiura), Ergasilus xinguensis and Gamidactylus sp. (Copepoda), and Isopoda (Braga patagonica), but branchiuran species were predominant. This was the first report of these parasite species for Leporinus fasciatus, Astyanax bimaculatus, Curimata incompta, Pygocentrus nattereri, Crenicichla cincta, Crenicichla johanna, Geophagus camopiensis, Pterophyllum scalare, Plagioscion squamosissimus, Hypostomus plecostomus and Propimelodus eigenmanni. Lastly, this study expands the range of occurrence of these six parasite species to the Matapi River basin in eastern Amazon.

          Resumo Este primeiro estudo investigou a fauna parasitária de crustáceos em 66 espécies de peixes da bacia do Rio Matapi, estado do Amapá (Brasil). Os peixes foram coletados bimestralmente no período de março de 2012 a agosto de 2013, nas estações de estiagem e chuvosa. Entre as 66 espécies (correspondendo a 722 espécimes) somente 11 espécies estavam parasitadas. A prevalência de infestação foi 2,2% e um total de 48 espécimes foram distribuídos em três grupos de parasitos. Esses incluem Branchiura (Argulus elongatus, Dolops reperta e Argulus multicolor), Copepoda (Ergasilus xinguensis e Gamidactylus sp.) e Isopoda (Braga patagonica), mas a dominância foi de espécies de branchiuras. Este foi o primeiro relato dessas espécies de parasitos para Leporinus fasciatus, Astyanax bimaculatus, Curimata incompta, Pygocentrus nattereri, Crenicichla cincta, Crenicichla johanna, Geophagus camopiensis, Pterophyllum scalare, Plagioscion squamosissimus, Hypostomus plecostomus e Propimelodus eigenmanni. Por fim, este estudo expande a ocorrência dessas seis espécies de parasitos para a bacia do Rio Matapi na Amazônia oriental.

          Checklist of Crustacea parasitizing fishes from Brazil

          Here we provide a checklist of the crustacean species parasitizing both marine and freshwater fishes from Brazil. We list a total of 134 species of parasitic crustaceans associated with 205 species of fishes in Brazil. The data from this study added to the checklist of Copepoda in Brazilian fishes published in 2007 give a total of 251 species of parasitic crustaceans associated with 279 fish species currently known in Brazil. The majority of species of Crustacea listed as parasites of Brazilian fishes are Copepoda with 186 species registered. A total of 741 parasite-host associations were observed. Copepoda was the group with more host-parasite associations, totaling 419 associations. When comparing these data with those recorded for the fishes from other parasite hotspots of Neotropics (Mexico and Caribbean), it is possible to affirm that the fauna of parasitic crustaceans of Brazilian fishes is the richest in the region.
