Timeline:

August 2017 - ongoing 

Objectives: 

To investigate the migration of Atlantic bluefin tuna in Scandinavian waters after a 50 year absence in the area (due to a collapse of the population/overfishing). Our questions include: Where do the tuna come from? Where do they go? How do they behave on a daily and seasonal basis? Our do they behave following an angling event? We also want to explore the physiological exhaustion that tunas experience from angling.

Funding: 

We rely heavily on volunteer anglers who devote time and resources to this project; ICCAT GBYP program; Tunforeningen 2019; the Fisheries Society of the British Isles

Results:

More than 500 bluefin tuna have been tagged with eletronic tags in Denmark and Sweden over the last 7 years. The analyses of the results are still under way.

Outputs:

One peer-reviewed publication (here) and several ICCAT reports.

Future steps:

We continue to tag bluefin tuna to gain a better understanding of their behaviour, habitat use, and potential threats.
