| Resumo: |
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.
