Fig. 2. Changes in plasma Na+, Cl, K+
(AC) and cortisol (DF) concentrations and gill
Na+/K+-ATPase activity (GI) in lake trout
(A,D,G), brook trout (B,E,H) and Atlantic salmon (C,F,I) following gradual
transfer from 0 p.p.t. to 10, 20 and 30 p.p.t. Salinities: before day 0, 0
p.p.t.; day 07, 10 p.p.t.; day 714, 20 p.p.t.; day 1435,
30 p.p.t. Symbols in AC: circles, Na+; triangles,
Cl; squares, K+. Each value represents the mean
± s.e.m., N=8. Groups with different lowercase letters are
significantly different (P<0.05, TukeyKramer test).
