Resumo: We studied the feeding aspects from 158 individuals of Serrasalmus spilopleura captured in Porto Colômbia Reservoir, situated on the Grande River, at the Paraná basin, between November 2001 and August 2002. Mesh nets were used to capture the individuals, with sizes ranging from 3 cm to 16 cm, between opposed knots set at sunset, and collected in the following morning; remaining exposed during approximately 12 hours. The analysis from the stomach content of the captured individuals showed a predominantly piscivore feeding habit, and exclusive to individuals over 22 cm. Aquatic insects were also found, complementing the diet of individuals belonging to smaller size groups, indicating a clear trophic ontogeny

Utilizaram-se redes de malhar com tamanhos entre 3cm e 16 cm entre nós opostos armadas ao entardecer e retiradas pela manhã, permanecendo expostas por um período de aproximadamente 12 horas. A análise da dieta dos exemplares mostrou-se predominantemente piscívora, sendo exclusivo para exemplares de comprimento padrão superior a 22 cm. Insetos aquáticos também foram ingeridos, complementando a dieta dos indivíduos pertencentes às menores classes de tamanho, demonstrando uma evidente ontogenia tróficaUniversidade Estadual De Maringá2008-03-24info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciBiolSci/article/view/133110.4025/actascibiolsci.v27i4.1331Acta Scientiarum.
