Haddock otolith section

Figure 19. Sectioned otolith from a 54-cm age-9 haddock collected in April on Georges Bank, showing the appearance of an off-center section. The first annulus cannot be clearly seen. Note the irregularly-shaped second annulus, the increased checkiness overall, and the unusual shape of the sulcus. This fish was aged using the otolith half nearer to the nucleus.
