Effects of acute and chronic stress on blood pH and HCO3− levels. Atlantic salmon were reared in low density (LD) and high density (HD) conditions with and without being subjected to an acute stress (AS) protocol at two sampling points (S1 and S2) and blood pH (A,C) and blood HCO3− levels (B,D) were analyzed. Statistics: 2-way ANOVA where a significant interaction were subjected to Sidak-corrected multiple comparisons. Main effects of density and acute stress (AS) are indicated by text in the figures and significant effects from the post-hoc test are reported as * p < 0.05, ** p < 0.01 and *** p < 0.001. Data are presented as individual values with the line representing the mean.
