Abstract
The effect of different salinity on float ing natures and early embryo development of fertilized eggs from Paralichthys olivaceus breed in sea water were studied. The research results showed that fertilized eggs floating in seawater with salinity above 30, 27.5 as a state of suspension, sinking under the salinity 25. Suitable salinity ranged from 25 to 45 in incubation period, and the optimum salinity ranged from 30 to 35. Hatching rate of fertilized eggs dropped significantly and deformity rate rose in juveniles with the salinity 15 ~ 20 and 45 ~ 50. The tolerance from salinity variation in gastrula stage was better than blastula stage and the blastula stage was better than 4 cells stage.关键词
