Resumo: The aim of this study was to describe and classify the food preference of fish species in Passa Cinco stream. The grade of feeding preference was applied to stomachs considered replete. This method consists of attributing values to food items found in certain species, according to the participation of each item in the analysed stomach. We analysed 576 full stomachs of 28 species. The autochthonous insects were the main constituents of the diets of these species, and the majority of ingested items classified as occasional. Allochthonous items such as plant debris, seeds and earthworms were associated with higher-order site. Of the total possible combination pairs of species, 29.4% showed high overlap, wich occurred mainly within species that consumed aquatic insect larvae. However, those species showed significant differences in the exploitation of food resources. Omnivory was common, showing the plasticity of the required species that inhabit environments as found in streams.
