Teledyne RESON Supports Bluefin Tuna Research in Danish Waters

9/30/2026



A donation from Teledyne RESON is helping support long-term research into the movements and behavior of Atlantic bluefin tuna returning to Danish waters.

Teledyne RESON​ has chosen to support the tuna tagging project led by DTU Aqua in collaboration with the Swedish University of Agricultural Sciences and the Danish Tuna Association. Running since 2016, the project brings researchers and recreational anglers together to build knowledge about the Atlantic bluefin tuna that have returned to Danish waters.

During the annual fieldwork near Læsø and Helsingør, anglers help locate and catch the tuna before trained teams tag and release them. The electronic tags record pressure, light and temperature.

"We are proud to support this research project. The return of Atlantic bluefin tuna to Danish waters is a remarkable story, and the more we learn about its movements, behavior and life cycle - the better equipped we are to understand and protect them. Supporting research like this is an investment in the knowledge we need to ensure that the tuna can thrive for generations to come."

 - Ole Søe-Pedersen, Teledyne RESON

Over almost a decade, approximately 800 tunas have been tagged with the involvement of approximately 800 volunteers across 100 boats. The resulting data is providing valuable insight into how long the fish remain in Danish waters, where they travel afterwards and where they spawn – in areas of the Mediterranean Sea near Mallorca, Sardinia, Tunisia and the Adriatic Sea.

By supporting the project, Teledyne RESON​ is contributing to continued research and a stronger scientific understanding of this remarkable species and its presence in Danish waters.
