Abstract: The present study focused on the fish fauna of the 44-yearold Coaracy Nunes reservoir in the northern Amazon basin, producing estimates of the growth constant (k), maximum and asymptotic body lengths and weights, natural mortality (M), the consumption/biomass ratio (QB) (intake of food by a group over a year), the Aspect ratio (Ar) of the caudal fin, growth performance (Φ), longevity, and trophic level for 45 fish species. Species collection was divided into eight sampling campaigns between May 2009 and July 2… Show more

“…These data can be useful for fisheries research and stock management, and also fill in gaps about the understanding of the local ichthyofauna. However, despite the recent increase of published LWR studied for Amazonian fishes (e.g., Freitas et al, ; Cella‐Ribeiro, Hauser, Nogueira, Doria, & Torrente‐Vilara, ; Giarrizzo et al, ), including studies in the same aquatic biogeographic region (Nobile et al, ; Sá‐Oliveira, Angelini, & Isaac‐Nahum, ), there is still much work to be done considering that the Amazon basin comprises the most diverse freshwater fish fauna in the world (Reis et al, ). It is especially true for low commercial interest species (Freire, Rocha, & Souza, ), such as those reported herein.…”

“…For study of parasites, specimens of Acestrorhynchus falcirostris (Acestrorhynchidae), Ageneiosus ucayalensis (Auchenipteridae), Geophagus proximus (Cichlidae), Hemiodus unimaculatus (Hemiodontidae), Serrasalmus gibbus (Serrasalmidae) and Psectrogaster falcata (Curimatidae) were collected in the Coaracy Nunes Reservoir (Fig. 1), a long-established ecosystem, about 40 years (Sá-Oliveira et al, 2015). A total of 296 fish specimens were caught during the dry season (October 2012 to February 2013) and rainy season (April to August 2013) at six sampling points, located at a distance of 889 ± 498 m (range: 544-1777 m) from each other (Fig.…”
