Lingcod (Ophiodon elongatus) lives along the west coast of North America from the Mexican border through the Aleutian Islands. It is not a Ling, nor a Cod, and is not closely related to any other fish genus.
Ling (Molva molva) is strictly a North Atlantic fish, from Spain to within the Arctic Circle, from Nova Scotia to the Arctic Circle, and along the southern coast of Greenland.
