Effect of acute and chronic stress on blood parameters. 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 plasma cortisol (A,D), blood glucose (B,E) and blood Na+ levels (C,F) were analyzed. Statistics: 2-way ANOVA where a significant interaction were subjected to Sidak-corrected multiple comparisons. Main effects of density and AS are indicated by text in the figures and significant effects from the post-hoc test are reported as * p < 0.05 and *** p < 0.001. Data are presented as individual values with the line representing the mean.
