The age-composition of the stock of cod in west Greenland waters in the years 1924 to 1938

In order to investigate the occurrence of the yearclasses in the stock of cod at West Greenland a great number of otoliths of cod has been collected and age-determined during the period: 1924 to 1938. Nearly all the cod from which otoliths have been taken are measured and sexed. Cod of the youngest groups, the I-, II- and III-group, have been fished for with the eel-seine near the shore. The length measurements and the results of the fishery for the youngest age-groups shall be dealt with in a future paper. Here the age-analyses on older cod only shall be mentioned.
