Haddock
[Melanogrammus aeglefinus]
A highly commercial North Atlantic fish closely related to cod found from the Arctic Circle to as far south as New Jersey and the north coast of France. They can get as large as 39 inches and 37 pounds.

Presumably prep and cooking for Haddock should be similar to Pacific Cod, but I'm not sure because we don't have haddock on the West Coast.
