Learning about Atlantic Salmon in Greenland via Satellite Tags

1337-x959-tagged-salmon-release-greenland.jpg“For ten days in October, NOAA Fisheries biologist Tim Sheehan spent 6-8 hours each day with a local fisherman trolling slowly in Igaliko Fjord in southwest Greenland, hoping to capture pre-adult Atlantic salmon. Their plan: capture and release all fish alive with a pop-up satellite tag attached to as many as possible, and hope the tags stay on between 5 and 10 months, recording the environmental conditions and the animal’s behavior in the waters around Greenland and during their journey home.
Atlantic salmon are an endangered species. Once common in many rivers and streams in the Northeast, they are now found in only a few rivers in Maine. Adult Atlantic salmon return to the rivers where they were born to spawn after spending up to two years at sea, part of that time in the waters off Greenland.”
