A conservation group says no wild Atlantic salmon have returned to a key river in New Brunswick, prompting concern for the fish's population health in the U.S. and eastern Canada.
The New Brunswick-based Atlantic Salmon Federation has been monitoring the Magaguadavic (mack-uh-DAY'-vick) River for the Canadian government since 1992. The group says this year is the first time that no wild salmon have returned to the river to spawn.
Atlantic salmon were once abundant in rivers of New England and eastern Canada, but they're now endangered or have disappeared in parts of both areas.
The fish suffer due to dams, loss of habitat, pollution and overfishing. The U.S.'s National Marine Fisheries Service is reviewing the Gulf of Maine's population, which is listed endangered under the Endangered Species Act.
