Blood and plasma parameters analyzed in the six different fish groups. Group identity: 0 min. seawater control (0 SW), 30 min. seawater (30 SW), 30 min. isoeugenol (30 I), 120 min. seawater (120 SW), 120 min. metacaine (120 M) and 120 min. isoeugenol (120 I). A) glucose, B) cortisol, C) osmolality, D) Na⁺, E) pCO₂, F) HCO₃ and G) pH. For cortisol (C) and osmolality measurements (D), n = 6 in all groups except 120 min. metacaine and 120 min. isoeugenol groups (n = 5). For the I-Stat measurements (A, D, E, F, and G), n = 6 in the 0 min. control group, n = 5 in the 30 min. group, n = 3 in the 30 min. isoeugenol group, n = 4 in the 120 min. and the 120 min. metacaine group and n = 5 in the 120 min. isoeugenol group. The horizontal line in the middle of the box plot show the median (50% percentile) of the sample. The top and bottom of the box show the 75^th and 25^th percentiles, respectively, whereas the top and bottom of the whiskers show the maximum and minimum values. An * denotes significant differences (P < 0.05) between the 0 min. control group and the other groups (Kruskal Wallis ANOVA).
