Feeding aspects of the rainbow runner, Elagatis bipinnulata, were studied in in the area surrounding the Saint Peter and Saint Paul Arquipelago, where they are captured by handline. A total of 309 stomachs of fishes of both sexes ranging from 46 cm to 101 cm furcal length were analyzed, out of which 192 stomachs presented some food and 117 were empty. Twenty-seven taxa were identified, represented by 12 taxa of fishes, 7 crustaceans, 5 cephalopods, 1 pteropod, 1 heteropod, and 1 tunicate. Euphausiacea, among micronekton species, were the main prey items, accounting for 79.2 % of total numbers and having been identified in 29.2 % of the examined stomachs. A remarkable predation was also observed upon flying fishes that gathered around the rocky islands for reproduction.
