S3 EP179: Mystery of the Migrators - Tracking Highly Migratory Species

In this guest lecture, Dr. Walt Golet from the University of Maine provided an in-depth exploration of the remarkable physiology and global movements of Atlantic bluefin tuna. Dr. Golet highlighted the species’ exceptional adaptations, such as their ability to regulate body temperature and sustain high-speed, long-distance migrations, which contribute to their status as apex ocean predators. The seminar discussed extensive lab research efforts, including the collection and analysis of over 12,000 bluefin tuna samples since 2011, focusing on biological data like age, growth, and stock origin to enhance stock assessments and inform management strategies. Dr. Golet also emphasized the importance of understanding the mixing between eastern and western Atlantic stocks, a factor critical to sustainable fisheries management. As an active contributor to the International Commission for the Conservation of Atlantic Tunas (ICCAT), Dr. Golet integrates his scientific findings into international policy discussions, aiming to ensure the long-term sustainability of bluefin tuna populations through informed, science-based management practices.
