The recent return of Atlantic bluefin tuna to northern Europe following the recovery of the east Atlantic stock has sparked substantial public and scientific interest. This is particularly true for recreational anglers in Denmark, who often consider Atlantic bluefin tuna to be the catch of a lifetime. This attitude has previously sustained a substantial recreational fishery for bluefin tuna with annual tournaments in Denmark, which peaked in the 1950s before the subsequent collapse of the stock during the 1960s.

- Ecosystem-based management (EBM) aims to create a sustainable approach that connects environmental, social, and economic factors in managing marine fauna, but there are challenges in linking these goals to practical assessments and management plans.
- The study suggests using an ecosystem-service framework at the population level for marine mammals as a way to identify indicators that can assess their contributions to ecosystem services and disservices.
- Preliminary findings indicate that existing data on indicators for marine mammals can support this approach, but further investigation is needed to address potential disagreements regarding the ecosystem service concept among stakeholders.
