Seasonal dynamics of condition factor and ionoregulatory parameters. Condition factor (a) and branchial Nka activity (b), nkcc1 (c) and cftr1 (d) mRNA levels in Atlantic salmon maintained in FW from March 3 through July 10. Means ± S.E.M. (n = 8). mRNA levels are presented as a fold-change from the March 3 group. Means not sharing the same letter are significantly different (one-way ANOVA, Tukey’s HSD test, P < 0.05)
