The eggs and larvae of rosy seabass Doederleinia berycoides (Acropomatidae) are described based on specimens reared from eggs artificially fertilized in September 2013. Fertilized eggs, measuring 0.80–0.83 mm in diameter, were buoyant, spherical and transparent with a single oil globule measuring 0.21–0.23 mm in diameter. Melanophores were present on the yolk, and embryo and oil globule after closure of the blastopore and appearance of myomeres, respectively. Hatching occurred 29‒35 hrs after fertilization when incubation temperatures ranged from 22.1–23.8˚C. Newly-hatched larvae (1.76–1.83 mm notochord length, NL) had melanophores on the head, dorsolateral and anterior parts of the trunk, and dorsolateral abdomen. Eggs after detachment of the caudal end of the embryo and yolk-sac larvae also had xanthophores on the embryo and trunk, respectively. The mouth opened at 2.51‒2.74 mm NL, the yolk being absorbed thereafter. Notochord flexion started at 4.19 mm NL, after which body depth increased rapidly, being completed at 5.53 mm standard length (SL). The dorsal and anal fin anlagen appeared at 4.19 mm NL, each fin, except pelvic fin, nearing the full adult complement at 5.53 mm SL. Head spination, including a supraoccipital crest, began to develop during the preflexion stage. Although the body proportions and head spination were closely similar to previous descriptions of larval D. berycoides after the preflexion stage, melanophores had appeared earlier and were more dense than in the latter.
