| Abstract: | Changes in plasma osmolality and gill Na+/K+-ATPase activity of the juvenile tongue sole (Cynoglossus semilaevis) were studied by abruptly shifting the of salinity from 30 to 0, 10, 20, 35 or 40. The results showed that the effects of the salinity on plasma osmolality and activity of gill Na+/K+-ATPase of the fish were significant (P<0.05). The peak values of plasma osmolality appeared on day 2 after the changes of salinity, and the plasma osmolality in each group was stablized on day 6. The similar trends were observed in the changes of gill Na+/K+-ATPase activity. The peak values of gill Na+/K+-ATPase activity appeared on day 6 after the changes of salinity, and was dimished gradually to the stable leve1 at day 9. The results of this study indicated that the tongue sole might have a great capability of acclimation to different salinities. |
