Abstract
Eighty eight wild cod were in October 1997 tagged with data storage tags placed inside the buccal cavity. The release site was approximately 12 nautical miles north-west of the Faroe Islands at 62o19’N 7o39’W (100 m). By August 1999 forty-one (47 %) were recaptured, all from Faroese waters. All cod stayed exclusively in warm (> 5 oC) Atlantic water and usually at shallow (90-130 m) and nearly constant depth (presumably at the bottom) during winter. Vertical migration was rare, but two cod showed very clear diurnal vertical migration, most likely feeding migration, at exactly the same time of the year. Spawning related activities could in some cases be detected by a change in depth.
