| Resumo: |
We qualitatively studied the gut contents of 20 specimens (36.1-71.3 mm standard length) of the pike cichlid Crenicichla britskii from a 100 m stretched second order stream running inside a small gallery forest in a large pasture area of Rio Aguapeí basin, State of São Paulo, southeastern Brazil. The diet, in terms of per cent composition, constituted primarily of aquatic insects (50%) (mostly immature forms), crustaceans (14.3%), unidentified organic material and filamentous green algae (both with 10.7%), followed by fishes and arachnids (both with 7.1%). Diet analysis indicates that C. britskii is a generalist insectivore with a relatively short digestive tube, which feeds on autochthonous items captured in a broad array of habitats such as in the water column or at the surface, buried in or over the bottom, or associated with macrophytes and submerged vegetation debris.
