Publications & Outreach

The results of this project were presented in 14 articles. Of these articles, 5 correspond to publications in international peer-reviewed journals (2 published, 3 in review). The remaining 9 articles were published as part of the proceedings of the meetings organized by the regional tuna fisheries management organizations (International Commission of the Conservation of Atlantic Tuna - ICCAT and Indian Ocean Tuna Commission - IOTC). Three more papers are currently in preparation and will be submitted to international peer-reviewed journals. Finally, the results of the project were presented into an internship report, 20 oral presentations (13 international, including 1 as keynote speaker) and 2 posters. They will also appear in the final report of the two PhD thesis (expected date: November 2020).
