The prey selection of hatchery-reared larvae of greater amberjack Seriola dumerili was investigated from 6 to 22 days post-hatching under a co-feeding condition with smaller prey rotifers and larger prey Artemia, and the results show that the feeding habits of larvae changed ontogenetically. The prey preference of larvae appeared to shift from rotifers in the preflexion stage, at a < 4.5 mm standard length (SL), through egg-bearing rotifers in the flexion stage, at a > 5 mm SL, to Artemia in the postflexion stage, at a > 5.5 mm SL. The majority of larvae with a > 7 mm SL could consume Artemia.
