Alaska Pollock
Gadus chalcogrammusAlso known as Pacific Pollock, Walleye Pollock, Snow Cod
Alaska pollock form immense, shimmering schools in the icy waters of the North Pacific, serving as a cornerstone of the marine food web. These slender, speckled cod relatives migrate vertically each day, feeding on krill near the surface at night and retreating to deeper waters during the day. As one of the world's most heavily harvested food fish, they support massive marine mammal and seabird populations while anchoring global seafood markets.
