Abstract

The goal of this work was to study the diet of Astyanax lineatus from the Taquaraçu Stream, in the region of Serra da Bodoquena, State of Mato Grosso do Sul, central Brazil. The fish were caught using a combination of electric fishing, seines and hoop nets. The stomach contents of 15 specimens was analyzed using the frequency of occurrence, in which the number of fish that contain certain item is expressed as percentage of total number of fish examined with the content. Our results indicate that A. lineatus is an euryphagic species, with a tendency to insectivory, with a predominance of aquatic insects in its diet.
