Embryonic development of Hexagrammos otakii and its relationship with incubation temperature
摘要
Abstract
The embryo development duration and characteristics of Hexagrammos otakii were studied, with each development stage being taken microphotography. The egg of H. Otakii was demersal, telolecithal, spherical with diameter of 1. 62～2. 32 mm. Incubation temperature had a significant effect on embryonic development of H. Otakii. With the increasing incubation temperature in an appropriate range, the incubation duration reduced; The incubation rate increased to the maximum of 79% at 16℃ , and then decreased. The deformity rate decreased to the minimum of 6% at 16℃ and then increased. Fertilized eggs hatch in about 20d under the conditions of 16℃ , 31 salinity, pH = 8. 0 and 600～1 000 lx light intensity.关键词
