Fig. 1. Whole Greenland halibut otoliths used for age interpretation by counting zones on the surface. Left: the centric left otoloth. Right: The a-centric right otolith. Top: Dried otoliths submerged in water used with the traditional method; Bottom: The same otoliths before drying, still wet after being frozen, used with the new method. The fish was 60 cm and caught in March, and markings denote typical interpretations of annuli with the traditional method (top left, estimated age to be 9 years) and with the new method (bottom right, estimated age to be 16 years).
