Résumé

Hoplias malabaricus behaves as a zoophagous and euryphagic species with a strong tendency to eat fish during its entire life. Fish begin to constitute its main food at approximately 200 mm standard length. Insects are important for fish smaller than 50 mm. Crustaceans are of lesser importance for both size groups. "Mojarras" (genus Astyanax), the characin Odontostilbe microcephala, and the catfish Pimelodus albicans are its main prey. The relative importance of each prey type varies with predator length. In high summer more food is eaten by H. malabaricus, and digestion rate, related to the higher temperatures, is also higher. During colder seasons feeding activities decreases markedly.
