|
Abstract: |
Fertilized eggs of high finned grouper, Cromileptes altivelis were obtained from induced spawning. The developments of the eggs were observed and studied in 1997. The egg was float, transparent, spherical in shape, and 810 μm in average diameter with a single oil globule. The hatching time was about 24 h and 10 min and the first egg hatched after fertilization at 25~27 ℃ and salinity 30. |
Key words: Cromileptes altivelis fertilized egg embryonic development |
