The federal government says saving Maine’s endangered salmon will require more dam removals, habitat restoration and aggressive hatchery programs.
The U.S. Fish and Wildlife Service has released a recovery plan for the Gulf of Maine salmon, listed as endangered in 2000.
The Gulf of Maine’s salmon population has plummeted since the 1800s. The wildlife service estimates 100,000 adult salmon returned to the Penobscot River in the 19th century. Less than 750 of the fish returned to spawn in Maine rivers last year.
The report states that the salmon also face threats such as climate change, competition for food with other species and inadequate regulation of water quality. It also says commercial fishing off the coast of Greenland remains a threat to the species.
