Table 2. One-way ANOVA results based on mean otolith edge (outer 100 μm) element:Ca values for Pacific bluefin tuna for exploring regional differences in otolith chemistry among the eastern Pacific (EPO), western Pacific (WPO) and south Pacific (SPO).
Only Mg:Ca was log transformed to meet normality assumption.
