Understanding the spatial ecology of commercially exploited species is vital for their conservation. Atlantic bluefin tuna (Thunnus thynnus, ABT) are increasingly observed in northeast Atlantic waters, yet knowledge of these individuals' spatial ecology remains limited. We investigate the horizontal and vertical habitat use of ABT (158 to 241 cm curved fork length; CFL) tracked from waters off the United Kingdom (UK) using pop-up satellite archival tags (n = 63).

- Biologging technology has been employed to track the behaviors and migrations of various wild animals, including a notable event involving the predation of an Atlantic bluefin tuna by an orca.
- The study details a 19-minute predation sequence where the tuna displayed high activity levels during its capture and subsequent handling by the orca.
- Unique datasets collected from both the tuna and orca give valuable insights into their energetic behaviors and patterns of interaction in the ocean.
Atlantic bluefin tuna (ABFT; ) is a highly migratory species. To investigate the migrations and vertical behaviours of ABFT migrating to Nordic waters, we deployed pop-up satellite archival transmitting tags on 25 ABFT off Norway (curved fork length: 228-292 cm). We obtained 16 full-year migrations, which differed between individuals, and physically recovered 13 tags, which provided 4699 days of archival depth and temperature data.
