Ages of 32 Arctic char (Salvelinus alpinus) were estimated from otoliths (surface-examined and broken-and-burned), vertebrae, cleithra, opercula, and subopercula. Six readers examined each structure three times, and the precision of these estimates among structures and readers was compared with mean...
