Figure 1. Otolith section from a 27 cm age 8 male redfish. As indicated by the markers, the first annulus separates from the grey settling zone and extends out towards the edges of the otolith. The second and third annuli are split zones which converge to form a single annuli along the proximal edge. Note the strong check between the third and fourth annuli. The fourth annulus is fairly weak but discernable, especially along the proximal and ventral edges. The fifth to eighth annuli are quite distinct and clear.
