McDonald's is advancing its seafood endeavors by adding Fish McBites to its menu. The bite-sized meal will be available in snack, shareable and large sizes, and the Chicago Tribune says that the juggernaut announced the new addition along with the news of its success in the fourth quarter of 2012. 

To accompany the Fish McBites, McDonald's will soon release new breakfast, burger and chicken selections. The company says the items are performing well in test markets, so they could be available sooner than later.
