Habitat North Atlantic Ocean and rivers that flow into it[2]
Life history Anadromous[2]
U.S. market status Only farm-raised Atlantic salmon sold[4]

Atlantic salmon (*Salmo salar*) is an anadromous fish in the family Salmonidae, native to the North Atlantic and its rivers. It hatches in freshwater, migrates to the ocean, and returns to rivers to spawn. In U.S. markets, only farm-raised Atlantic salmon is sold, as wild populations are endangered and federally protected.

Context

Atlantic salmon is a species distinct from Pacific salmon, though both are commonly sold as "salmon" in markets. In the U.S., the Gulf of Maine distinct population segment is listed under the Endangered Species Act, and only farm-raised fish appear in seafood markets [4]. Wild U.S. populations are now limited to a handful of rivers in Maine [1].

  • Atlantic salmon are endangered and federally protected in the U.S. [4]
  • Most Atlantic salmon return to spawn in the same river where they hatched. [3]
  • Commercial fishing for Atlantic salmon in the U.S. is prohibited. [4]
