Glucose levels were higher in exposed fish compared with the control at multiple time-points. Cortisol levels exhibited a highly significant difference between groups ( P < 0.001) ( Table 3 ), with post hoc analysis revealing significant differences between the control and all time-points (0, 2, 12, and 24 h), as well as between 0 and 2 h ( Figure 3e ).
