Newly hatched black porgy larvae (Acanthopagrus schlegeli) swam to the surface, with the mouth and anusstill closed and were 1.90?2.11 mm (mean, 2.0 mm) in total length (TL). The larvae were 2.71?2.94 mm TL (mean, 2.82 mm)on day 2 after hatching. At this time, about two-thirds of the yolk was absorbed, the bladder and intestines had formed, andthe mouth and anus were open. Total length was 4.32?4.66 mm (mean, 4.45 mm) at the post-larval stage on days 5?6 afterhatching, and the yolk and oil globule were almost absorbed. The end of the notochord began to flex, and 6?8 caudal fin rayswere visible. The larvae were 15.37?16.1 mm TL (mean, 15.83 mm) at the juvenile stage on days 30?32 after hatching, andthe number of rays in all fins was completely revealed.
