Add to ORKGIntroductory 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 signals were received by means of sonars, SIMRAD SU for 18 kHz and SIMRAD SK 120 for 120 kHz. Both fishes were tracked for approximately 8 hrs. The two fishes showed some different behaviour. The first one changed swimming speed and position all the time within a limited area while the other moved slowly around within an open area
