Resumo: Studies were performed on various aspects related to the feeding of Eigenmannia trilineata in the upper Paraná River floodplain, from June 1993 to July 1994, at four places with different types of bottom and waters speed. A number of 279 fish had its stomachal contents analyzed by occurence and point methods in which it was applied on its frequencies the feeding index. Two hundred an sixty two specimens were utilized to the analysis of the feeding activity that it was based on frequency and middle degree of stomach repletion. For the morfological analyse utilized 12 individuals. It was verified fourteen items on species diet which it was found chiefly Chironomidae (Diptera) and detritus. Seasonal, area variations were verified in feeding activity and the participation of constituent items in diet. The results showed that the species presents nightly and benthophagous habits, with morfological characters of the carnivorous species.
