Note
Egg and larval development of the Nassau grouper, Epinephelus slrialus, is described from laboratory-reared specimens. Egg diameters averaged 0.92 mm (0.86-0.97 mm), and those of the single oil globule averaged 0.24 mm (0.20-0.26 mm). No pigmentation was discernible on embryos. Newly hatched larvae measured 1.7-1.8 mm notochord length, and were inconspicuously pigmented. A characteristic pigment pattern that persists during larval development first appeared on late yolk-sac larvae-a mass of pigment on the ventral midline and lateral surface of the caudal peduncle, and on the dorsal and lateral surface of the gut.
