Results of one-way ANOVAs, respectively, Kruskal–Wallis one-way ANOVAs performed to investigate potential differences of osmolality and ion transporter net O₂ demand from isolated gill experiments between differently exposed fish groups (low PCO₂ = 550 µatm; medium PCO₂ = 1200 µatm and high PCO₂ = 2200 µatm) at 10 °C, respectively, 18 °C
