Cod are a species of whitefish, from the family Gadidae. They can be found in the cold, cool waters off the coasts of the Atlantic and the Pacific, specifically, in the Artco-Norwegian region, the North Sea, the waters around Alaska, and in the waters of the north Atlantic surrounding the UK. Cod is a moist and flaky whitefish that is low in fatty oils and high in protein, making it an exceptionally healthy part of any meal. The popular English platter, fish and chips, uses cod as the main ingredient. Portugal and parts of the Basque Country prize the fish an it is considered a heritage food, playing a large part in many of the nation’s traditional recipes. The fish, with its mild flavor and delicate white flesh is so popular that it is being overfished in many regions, leading to huge depletion in cod population. Cod sustainability, therefore, is becoming increasingly important.
