Description

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.
