摘要：

1. Kidney, oesophagus and gill Na+-K+ ATPase activity and serum Na+, K+ and Cl-concentrations are evaluated in European sea bass during experimental acclimation to fresh water. 2. Kidney and oesophagus ATPase increase in low salinity and reach a maximum in fresh water. 3. Gill ATPase decreases during the acclimation trials and rises again to normal values after a 3-week stay in fresh water. 4. Na+ and K+ serum concentrations decrease during the trials and increase back after a 3-week stay in fresh water. 5. The correlations between enzymatic activities, serum ion concentrations, morphological changes and environmental salinity are discussed.
