Abstract
The Balistidae, especially Balistes vetula are commom fishes in tropical waters from Northeastern Brazil. Studies about these fishes captured at the coastal area of Recife between Pina; Boa Viagem, Piedade and Candeias beaches were carried out in order to determine the diet, and to verify a possible diet diversification between the sexes, and times of the year. Males and females had a food diet consisting mostly of molluscs belonging the classes Scaphopoda, Bivalvia, Gastropoda and crustaceans and fishes. Echinoderms, foraminifera, bryozoa, sponges, polychaete worms, coelenterates and brachiopods were also observed in smaller proportions. Both males and females had a carnivorous benthic diet. Growth and changes in the seasons were not reflected by changes in the diet.
