Fig. 3. Principal component analysis (PCA) biplot of specific growth rate (SGR),
oxidized glutathione (GSSG), total glutathione (tGSH), reduced glutathione
(GSH), oxidative stress index (OSI), superoxide dismutase (SOD), catalase
(CAT), glutathione peroxidase (GSH-Px), metallothionein (MT) and cytochrome
P4501A (CYP1A) in liver samples of Atlantic cod exposed for 6 weeks to either
45% O2, 76% O2 or 145% O2 saturation. Circles
drawn in free hand indicate separate grouping of 45% O2 (L1-L6) and
145% O2 (H1-H6) samples. N1-N6 are normoxia samples.
