- We studied feeding habits of four fish species in two watershed at APA - Área de Proteção Ambiental (Area of Environmental Protection) in São Pedro and Analândia, State of São Paulo, southeastern Brazil. Feeding Preference Degree (FPD) was used to demonstrate the importance of each food item for the species of both basins. Feeding habits of both species of lambari was variable. The allochtonous items such as insects, autochtonous items, and vegetal material were very important, characterizing omnivory. The bagre (Rhamdia quelen) fed mainly on insects at the Jacaré-pepira Basin and also on fishes at the Corumbataí basin. The cascudo Hypostomus strigaticeps ingested autochtonous vegetal material and sediments at both basins.
