Food habits of 232 individuals belonging to 16 families, 21 genera, 26 species of the Pisces, 2 families, 2 genera, 2 species of the Cephalopoda and 1 family, 1 genus, 1 species of the Brachyura were investigated to study on the feeding relationships between the released artificially－bred juveniles of the red－spotted grouper, Epinephelus akaara and other fishes inhabiting the rocky reef of Ibukijima Island. Young of E. akaara was fed by scorpion fish; Sebastiscus marmoratus, jack; Trachurus japonicus and squid; Sepioteuthis lessoniana. Other predators (ex: sculpins, other scorpion fishes, red－spotted grouper (adult), Octopus) inhabiting this area have a possibility to be potential predators on E. akaara. Furthermore a lot of fishes feeding on small crustaceans compete with E. akaara for food.
