3.1.3. Na+, K+ ATPase specific activity
Na+, K+-ATPase activity in the gills and kidney of FW fish remained
unaffected upon acidic acclimation at pH 5.2 for 48 h but
a significant (P < 0.01) inhibition in the gill Na+, K+-ATPase activity
occurred at pH 4.2 (Fig. 3A). A reversal of this inhibition was obtained
(P < 0.05) in the fish when kept for 96 h post-acidic acclimation
in clean freshwater (Fig. 3A).
