Fig. 2. Gill Na+/K+-ATPase activity of Arctic char, Atlantic
salmon and rainbow trout acclimated to freshwater (control) or to seawater
(32
) for up to 30 days. *Activity is significantly higher
(P<0.05) than in both freshwater control groups and the
corresponding 1, 2 and 4 day seawater-acclimated group (dependent on species);
aactivity is also significantly higher (P<0.05) than
the corresponding 10 dayseawater group;
freshwater Atlantic
salmon had significantly higher activity than both Arctic char and rainbow
trout freshwater control groups. Sample size for each group ranged from 5 to 8
and is listed in Results.
