Abstract

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
