McDonald's used the Dollar Menu to lift its profit in the latest quarter. Now the world's biggest hamburger chain is turning to a pipeline of new menu items to boost slumping sales, starting with "Fish McBites."

The company is hoping to beat back intensifying competition and economic pressures with the lineup, which includes new burgers, chicken entrees and breakfast offerings.

The Fish McBites, which will come in three sizes and use the same Alaskan pollock used in the Filet-O-Fish, are set to be launched as a limited-time addition in February.
