Sažetak
The embryonic and early larval development of the laboratory-reared dusky grouper Epinephelus marginatus (Lowe, 1834)are described and illustrated. The eggs, with a mean diameter of 846.68(SD=41) um and a range from 736-940 um, were spherical and transparent with transparent chorion. Embryonic development lasted 30 hours at 23oC. Newly-hatched larvae were 1.52(SD=0.066) mm in length. Absorption of the yolk sac was complete after the fourth day, when larvae reached 2.63 (SD=0.123) mm in total length. The mouth opened 72 hours after hatching, and was in function after 96 hours, with an opening diameter ranging from 250-300um. larvae had two fields of intensive pigmentation, one above the intestine, and the other between the anus and the end of the notochord.
