International Council for the Exploration of the Sea (ICES)It's World Fish Migration Day!
We asked the Chair of our Working Group on North Atlantic Salmon (WGNAS), Martha Robertson (Research Scientist, Fisheries and Oceans Canada), what fascinates her about this magnificent migratory fish:
“The complexities of the Atlantic salmon life cycle have always intrigued me. We have very little knowledge regarding their long migrations at sea and the factors that determine their survival. Researchers around the North Atlantic are currently using advancements in telemetry technologies to better understand this key component of the their life cycle.”
Martha tells us that many Atlantic salmon migrate from their natal river in North America to feed in the waters off West Greenland, a distance of 1000 to 4000 km. Researchers from the Atlantic Salmon Federation (ASF), National Oceanic and Atmospheric Administration (NOAA) , and Fisheries and Oceans Canada (DFO) are using satellite telemetry to track the migration of Atlantic salmon from Greenland back to their natal river in North America.
