Resumo: 	Serrasalmus brandtii and Pygocentrus piraya are two common piranha species in the Barragem da Pedra Reservoir, rio de Contas. In order to identify the diet composition of the two species, monthly collections were performed at three sites between May 2001 and April 2003, using two gill nets of different mesh sizes cast at the beginning of the day and visited after 6, 12 and 24 h. The qualitative composition of the diet was analyzed by determining the frequency of occurrence. Comparison of the two species showed a higher relative abundance of S. brandtii (151) compared to P. piraya (55). The food items most frequently found in the stomachs of the two species were fins, fish and shrimp. Serrasalmus brandtii showed a greater feeding plasticity than P. piraya.
