Stress parameters (cortisol, glucose and lactate) in the plasma of Atlantic salmon subjected to handling-confinement stress. The stress test was performed before the start of PAA application and at 45 days thereafter. Values presented are mean ± SE of 8 individual fish per sampling point. Different letters denote a significant difference. Asterisk (*) indicates a significant difference between two groups at a particular timepoint. Note that in cortisol, uppercase was for the group before exposure while lowercase was for the group at day 45 of intermittent exposure
