Preliminary results of the coalfish taggings 1954-58
From 1954 to 1958 more than 7 800 tagged coalfish were released, mainly in North Norway, of which about 2 600 recoveries have been reported. During the summer months the coalfish seem to be fairly stationary within limited feeding areas, and the large mature fish appear to be visiting the same distr...
