ORLANDO, Fla. -

McDonald's says it will be the first national restaurant chain to carry a label from a group that certifies sustainable fishing practices.

The blue "ecolabel" from the Marine Stewardship Council certifies that the Alaskan Pollack used in McDonald's Filet-O-Fish sandwiches come from suppliers with sustainable fishing practices.

The Marine Stewardship Council also partners with other major chains including Wal-Mart Stores Inc. and Whole Foods. The nonprofit group is paid a royalty by companies that use its label.

Other groups also rate sustainable fishing practices.   Last year, for example, Whole Foods also stopped carrying wild-caught seafood that's "red-rated." That indicates it's either over-fished or caught in a way that harms other species. The color system is determined by the Blue Ocean Institute and the Monterey Bay Aquarium in California.
