Alaska pollock (Gadus chalcogrammus), a species of cod (Gadus) found in the North Pacific ocean, is used as food globally. Compared with common pollock, Alaska pollock is milder in taste, whiter in color, and lower in oil content. Alaska pollock fillets are commonly packaged into block molds that are deep frozen and used throughout Europe and North America as raw material for high quality breaded and battered fish products. Portions cut from frozen Alaska pollock fillet blocks are the most common choice for fast food restaurant fish sandwiches, for example in the McDonald's Filet-O-Fish.
