From: Natal origin and age-specific egress of Pacific bluefin tuna from coastal nurseries revealed with geochemical markers

Figure 3

Mean geochemical profiles developed using element:Ca data from all Pacific bluefin tuna collected from the Ryukyu Archipelago in the East China Sea (N = 56, Table S2). Mean profiles shown separately for each of the six element:Ca ratios (Li:Ca, Mg:Ca,m Mg:Ca, Zn:Ca, Sr:Ca, Ba:Ca) along the laser path from the otolith core to 2000 µm. Blue lines represent mean values and shading denotes 1 SD. Area of laser path used to estimate natal origin (0–500 µm) is denoted; ___location on geochemical profile corresponding to 180 and 360 days post hatch (dph) is also provided.
