Resumo: | Seasonal variation of the food items of the "bagre-urutu", Genidens genidens is analysed based on monthly samples between September, 1993 and April, 1995 at the Guaratuba Bay, coast of Paraná. The stomach contents of 105 fish is analysed by the Occurrence Frequency Method and 41 of these have also been analysed by the Volumetric Method. Matching both methods using the Preponderance índices, a larger incidence of decapods is determined, followed by other crustaceans, molluscs, polychaets, fish, and plant material. The data show the existence of a strong seasonal variation in the diet.
