Última Diet of Iheringichthys labrosus (Pimelodidae, Siluriformes) in the Itaipu Reservoir, Paraná River, Brazil-Paraguay BABT Abes,Sara da Silva; Agostinho,Angelo Antonio; Okada,Edson Kiyoshi; Gomes,Luiz Carlos. Iheringichthys labrosus is a secondary commercial fish species in the Itaipu Reservoir, but it is important in other reservoirs of the basin. However, little information exists about this species in the literature. The purpose of this study was to describe the diet of this species in the Itaipu Reservoir. Stomachs of 306 fishes were analyzed, collected from October 1994 to September 1996 in the differents zones of the reservoir (according to a longitudinal gradient). The reservoir was separated into riverine (upper reach), transitional (middle reach), and lacustrine (next to the dam) zones. Main items in the diet of I. labrosus were aquatic insects (mainly Chironomidae) and mollusks (mainly Bivalvia). Their presence in the diet did not vary according to...

For a dietary study, specimens of Astyanax bimaculatus, Astyanax schubarti, and Moenkhausia intermedia were caught monthly with seines-nets in six lakes (Pau Veio, Porto Rico, Três Amigos, Mutum, Pontal, and Canal do Meio), on the floodplain of the Upper Paraná River, from March 1992 through February 1993. We analyzed stomach contents of 599 A. bimaculatus, 293 A. schubarti, and 394 M. intermedia, by the Occurrence and Points methods, combined in the Alimentary Index (AI). This analysis revealed that these species have broad dietary spectra. A. bimaculatus was an omnivore, with a tendency toward herbivory-insectivory. In most of the lakes it consumed terrestrial insects, followed by higher plants and microcrustaceans. A. schubarti was an omnivore,...
