Following his and Alaska Governor Sean Parnell’s recent success with Wal-Mart Stores Inc., U.S. Sen. Mark Begich will continue his campaign requesting international food-chains stock Alaskan seafood.

Begich on Friday wrote Sodexo USA President and CEO George Chavel asking that the corporation serve Alaska seafood not certified through the Marine Stewardship Council. In late June, Begich made the same request of Wal-mart Stores Inc. CEO Michael Duke.

And, Thursday, Begich shipped a halibut fillet to Domino’s Pizza Headquarters in Michigan, as a statement of concern about the pizza chain’s commercial “Powered by Pizza.” In a note, Begich asked Domino’s Pizza to stop being “halibut-haters.”
