Overview

Coalfish pollock (Pollachius virens) is a marine fish species in the cod family Gadidae. It is known for its firm, white, slightly oily flesh and mild flavor. In the United Kingdom and Ireland it is commonly called coley or saithe, while in North America it is often grouped under the name pollock.

Origin and history

Coalfish pollock is found in the North Atlantic Ocean, ranging from the Barents Sea to the Bay of Biscay in the east, and from Greenland to North Carolina in the west. It has been a commercially important food fish in Northern Europe for centuries, particularly in Norway, Iceland, and the United Kingdom. In the United States, the species is less commonly marketed under its own name and is often sold as pollock, a label it shares with the closely related Pollachius pollachius [1]. However, in U.S. commercial markets, the term “pollock” most often refers to Alaska pollock (Gadus chalcogrammus), a different genus, not Pollachius spp. The two Pollachius species are distinguished by jaw length: P. virens has a shorter lower jaw than P. pollachius [1].

Varieties and aliases

  • Saithe (common name in the UK and Ireland)
  • Coley (common name in the UK)
  • Boston blues (a North American market name that can be ambiguous; it may also refer to other fish species)
  • Coalfish (common name in the UK and North America)
  • Pollock (shared name with Pollachius pollachius in the U.S.)

Culinary uses

Coalfish pollock is typically filleted and cooked by frying, baking, grilling, or poaching. Its firm flesh holds up well in stews and chowders. In the UK, coley is occasionally used in fish and chips, though it is considered less premium than cod or haddock. In Norway, it is sometimes salted or dried. The flesh is slightly darker than cod and becomes white when cooked. It pairs well with butter, lemon, herbs, and root vegetables.

Cross-cuisine context

Coalfish pollock has no direct analogue in Mexican cuisine, where freshwater fish such as tilapia and catfish are more common, and marine white fish like huachinango (red snapper) are preferred for ceviche and Veracruz-style preparations. In East Asian cuisines relevant to Los Angeles, the closest analogue is myeongtae (pollock in Korean), though that refers to Gadus chalcogrammus (Alaska pollock), a different genus. In Japanese cuisine, the similar species suketoudara (Alaska pollock) is used for surimi and kamaboko. Coalfish pollock is not typically used in these preparations.

Notes for cooks

  • Coalfish pollock can be substituted for cod or haddock in most recipes, though it has a slightly stronger flavor and darker raw flesh.
  • The skin is edible and crisps well when pan-fried.
  • Fresh fillets should be firm, moist, and free of strong fishy odor. Cooked flesh should flake easily with a fork.
