March 13, 2016 (AP) — Preventing the long-imperiled Atlantic salmon from disappearing from American waters will require the U.S. to put pressure on Inuit fishermen in Greenland to stop harvesting a fish that has fed them for hundreds of years, federal officials say.

The salmon were once found from Long Island Sound to Canada, but their population has cratered in the face of river damming, warming ocean waters, competition for food with non-native fish and, officials say, continued Greenlandic fishing.

Now, federal officials have outlined an ambitious plan to try to save the Atlantic salmon that they say will require removing dams, creating fish passages and fostering cooperation with Inuit fishermen some 2,000 miles away from Maine, where most of America’s last wild Atlantic salmon spawn.

“We’ve tried everything possible to negotiate with Greenland to find alternatives to find out how they can lessen impacts on U.S. fish,” said Dan Kircheis, a fisheries biologist with the National Marine Fisheries Service. “This is part of their culture, this is part of who they are, this is something they’ve always done. We are trying to work with them to realize the fish they are fishing for originate in Canada, in U.S. waters, in Europe, and these populations are in decline.”
