【 摘 要 】

The trophic relationships of a fish community were studied in two basins subjected to a strong human pressure in the interior of the State of São Paulo, southeastern Brazil. A total of 211 stomachs of 14 species were analyzed. Diets varied greatly, with the occurrence of piscivory, benthophagy, insectivory, herbivory, and illiophagy. Food items were described for each species and a great amount of insects was registered. Allochthonous and autochthonous food items showed different importance degrees according to the species analyzed. Stomach fullness was high in spring and summer in both basins; these areas were used as reproduction and foraging sites for the studied species.
