Forsøk med akustiske merker i Lofoten i mars 1974
Introductory experiments on acoustic tagging were carried out on cod in Lofoten in March 1974. The research vessel used 'was «G. O. Sars» because of her excellent sonar equipment. Two fishes were tagged. The tags used were pure transmitters — one working on 18 kHz and the other on 120 kHz. The...
