Effects of time-course freshwater (FW) to seawater (SW) transfer on (a) plasma Na+ concentration (N = 6); (b) NKCC1α expression in gill; (c) NKCC2β expression in anterior (AI) and middle (MI) intestine of eels (N = 5). During initial transfer, eels drink SW copiously (arrow) and expose the gill to SW. Plasma Na+ was not increased suddenly (endurance phase), subsequently increased during the acclimation period, and gradually established to a new baseline of lower level after SW 7 d (acclimation completed). Similar delayed transient increase was found among NKCC2β expression in the intestines while branchial NKCC1α and CFTRb expression increased significantly after SW 7 d. Statistical differences among different time are indicated by alphabet letters (p < 0.05) after one way ANOVA, Tukey’s test
