Stress, health and welfare blood physiological parameters (mean ± SD) measured at the two different sampling points (T3 and T4) in the conventional diet (white bar; n = 18–20) and the low marine protein diet (blue bar; n = 18–20) groups. Parameters monitored are cortisol (nmol/L), glucose (nmol/L), lactate (nmol/L), hematocrit (%), hemoglobin (g/dL), red blood cell count (RBCC; 106 cells/mm3), adrenaline (ng/mL), noradrenaline (ng/mL) and absolute level of Hsp70 (number of copies/µl; measured in pull of organs). Symbols indicate significant different between the two sampling times (*: p < 0.05; **: p < 0.01 and ***: p < 0.001). When an effect of diet was detected, it was indicated on the top right of each graph using colored squares. Different letters indicate statistically significant differences between the different groups (diet groups and sampling times) while NS indicates no significant difference neither between diet groups nor sampling times (GLMM followed by Tukey’s HSD post-hoc test; see details in Table S3).
