Abstract: The embryonic developmental process of Haliotis ovina in the seas of China were observed microscopically to understand the life activity of H. ovina in ontogenesis. Observations showed that H. ovina mature eggs were spherical and beige,with an average egg diameter being（ 0. 19 ± 0. 02） mm. In the sea water under the salinity of 32 ‰ and water temperature of 28 ℃,it took 390 min for H. ovina to hatch from fertilization,with an average cumulative temperature of 156- 182 ℃ ·h-1. Morphological and characteristic observations showed the embryonic development process could be divided into 4 stages,fertilized egg stage,cell division stage,gastrula stage and trochelminth larval stage,and 11 development periods. H. ovina developed embryonically about 1hour faster than Haliotis discus hannai developing under suitable conditions but slower than H. diversicolor and H. asinine.
