Resumo: The present study was conducted at the Córrego Andorinha on the eastern slope of Ilha Grande and aimed to determine the alimentary daily rhythm of Bryconamericus microcephalus. Fishes were sampled at a 4 hours interval over a 24 hours period during winter 2002 and summer 2003. Gut fullness was determined according to a numerical scale ranging from 0 (empty gut) to 3 (full gut). No differences were registered for the daily ration estimates between seasons. It is concluded that B. microcephalus is a diurnal feeding species, as the high values of gut fullness occurred between 11:00 AM and 3:00 PM.
