Embryonic, larval and postlarval development of Haliotis asinina Linneù 1758 in laboratory condition
A total of 29 abalones Haliotis asinina Linneù was conditioned to photo-period of 12 h. light and 12 h. darkness. About 40-50% of 19 ripe abalones began to spawn 17-20 days after conditioning. The trochophore larvae occurred at 5-7 hours and the late veliger larvae appeared after 24-27 hours. Most of the late veliger metamorphosed to early creeping larvae after 29-32 hours. The first respiratory pore of the juvenile appeared after 30-40 days of rearing.
