Hoplosternum Uttorale (Hancock, 1828) is an abundant species in the lagoons of the upper Paraná river floodplain. This species was sampled in Patos and Guaraná lagoons in the flood period (November/92-May/93) and low water period (June-October/93). To analyse food contents in the diet were analysed stomach of 91 adults. Twenty seven food items were recorded, among them, Testaceae, Nematoda, microcrustaceans, quironomids and organic detritus were predominant. These items allows to characterize the species as bentivore. To study feeding activity were analized 565 adults stomach contents. Food intake was more intense during flooding. Considering diel variation, the species started to eat during dusk, increasing during night, stopping to eat during daytime.

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,...
