Overview

Alaska pollock (Gadus chalcogrammus, formerly Theragra chalcogramma) is a semipelagic schooling fish of the cod family Gadidae, native to the North Pacific with the largest concentrations in the eastern Bering Sea. It has mild, white, flaky flesh with a clean flavor and a slightly firmer texture than Atlantic cod. Despite the common name, it is not a member of the Pollachius genus that includes Atlantic pollock.

Origin and history

Alaska pollock is a cold-water species whose range spans the Bering Sea, Gulf of Alaska, and the Sea of Okhotsk. Commercial harvest began in earnest in the mid-20th century, and by the 1970s it became one of the largest single-species fisheries in the world by volume. The species is managed under U.S. and international quotas. In Korean culinary tradition, pollock (myeongtae) has been dried and processed for centuries, particularly in the mountainous Gangwon region where cold winter winds enable natural freeze-drying.

Varieties and aliases

  • Walleye pollock (alternate common name)
  • Myeongtae (명태, Korean name for fresh pollock)
  • Hwangtae (황태, Korean: pollock dried through repeated freeze-thaw cycles)
  • Bukgeo (북어, Korean: dried pollock, typically split and air-dried)
  • Nochi (Korean: frozen pollock)
  • Saengtae (생태, Korean: fresh pollock)
  • Dongtae (동태, Korean: frozen whole pollock)
  • Cod (often mislabeled in commercial contexts; not a true cod but in the same family)

Culinary uses

Alaska pollock is widely used in processed seafood products including surimi (imitation crab), fish sticks, and fast-food fish sandwiches due to its mild flavor and low oil content. In Korean cuisine, the fish is transformed into many named products based on size, age, and preservation method. Hwangtae is prized for soups and braises; bukgeo is commonly used to make bukgeoguk (dried pollock soup) or shredded as a side dish. Fresh pollock (saengtae) appears in stews and grilled preparations. The fish is also popular in Japanese cuisine as a component of kamaboko (fish cake) and in Russian cuisine as a staple for frying and baking.

Cross-cuisine context

Alaska pollock has no direct analogue in Mexican cuisine. The closest functional comparison might be to dried fish products such as bacalao (salt cod), which entered Mexican cooking through Spanish colonial influence and appears in dishes like bacalao a la vizcaína. However, bacalao is Atlantic cod, not pollock, and is salt-cured rather than freeze-dried. The Korean drying tradition for pollock is distinct: hwangtae is freeze-dried by natural winter winds rather than salted, producing a different texture and rehydration behavior.

In the broader LA-relevant cuisine corpus, pollock’s role as a surimi base connects it to Japanese kamaboko and chikuwa, and to the Filipino fish ball (bola-bola) tradition. These are functional analogues rather than direct substitutes.

Notes for cooks

  • Dried pollock (bukgeo, hwangtae) must be rehydrated before cooking. Soak in cold water for 10 to 20 minutes, then squeeze dry and shred.
  • Fresh pollock spoils quickly. Look for bright eyes, red gills, and firm flesh that springs back when pressed.
  • For surimi-based dishes, Alaska pollock is the standard raw material. Substitutions with other white fish (Pacific whiting, Atlantic cod) will change texture and binding properties.
