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

Figure 1

Thin section of Pacific bluefin tuna sagittal otolith displaying location of laser path with green highlighted section of line indicating the portion of the laser scan used to create geochemical profiles (top). Isolated region of otolith thin section corresponding to the geochemical profile along the 2000 µm path was matched to predicted age or days post hatch (dph) from otolith microstructure analysis (bottom). Position of daily increments along the laser scan were estimated for a series of otoliths and grey lines represent estimated age contours at specific intervals (dph).
