Eel Migration: One of the Top 10 Discoveries of 2016 According to Québec Science
The efforts of researcher Martin Castonguay (Fisheries and Oceans Canada) and his colleagues, Julian Dodson (Université Laval), Mélanie Béguer-Pon (Université Laval and Dalhousie University), José Benchetrit (Université Laval) and Shiliang Shan (Dalhousie University) are among the 10 most impressive discoveries in Quebec in the past year according to Québec Science magazine.
These efforts shed light on the over 100-year-old mystery of eel migration to the Sargasso Sea. By marking eels with satellite tags that continually record water temperature and depth as well as light, the researchers reconstructed the eels' migration routes to their breeding ground—over a distance of some 2400 km! They also found that eels very likely used Earth's magnetic field as a navigational guide.
To be selected, each discovery must have been the subject of an article in a scientific publication between October 1, 2015, and October 31, 2016. The public was once again invited to vote for its favourite discovery; the research team whose discovery garnered the most votes received the "Prix du Public Québec Science Découverte de l’année 2016". This is the team of Sylvain Hamel, of the nanorobotic laboratory of Polytechnique Montréal.
