Overview

The Atlantic wolffish (Anarhichas lupus) is a marine fish found in the North Atlantic Ocean, known for its distinctive, eel-like body and powerful jaws with canine-like teeth. Its flesh is firm, white, and mild-flavored, often compared to lobster or cod in texture.

Origin and history

Atlantic wolffish inhabit cold waters along the continental shelves of the North Atlantic, from the Gulf of Maine to Greenland and across to the Barents Sea [1]. They have been fished commercially in Northern Europe and eastern Canada for decades, though they have never been a primary target species. The species is currently listed as a Species of Concern by NOAA due to population declines linked to overfishing and bycatch [1]. The wolffish is also known regionally as seawolf, Atlantic catfish, ocean catfish, devil fish, wolf eel, or sea cat.

Varieties and aliases

  • Atlantic wolffish (Anarhichas lupus) — the primary species
  • Spotted wolffish (Anarhichas minor) — a related species with similar culinary use
  • Northern wolffish (Anarhichas denticulatus) — another related species
  • Regional names: seawolf, Atlantic catfish, ocean catfish, devil fish, wolf eel, sea cat

Culinary uses

Atlantic wolffish is valued for its firm, boneless fillets that hold up well to grilling, baking, poaching, and pan-searing. The flesh is naturally sweet and does not flake apart easily, making it suitable for stews and chowders. In Scandinavian cuisine, wolffish is often served simply with butter and dill. In Icelandic cooking, it may be salted or dried. The skin is sometimes used to produce leather.

Cross-cuisine context

Atlantic wolffish has no widely recognized analogue in Mexican cuisine, where freshwater fish like tilapia and catfish are more common, and marine fish like huachinango (red snapper) are preferred for ceviche and Veracruz-style preparations. The firm, non-flaking texture of wolffish is more comparable to monkfish or lobster meat than to typical white fish fillets. In Japanese cuisine, the texture might be compared to anago (saltwater eel) or to firm-fleshed white fish used in tempura, though wolffish is not traditionally used in Japanese cooking.

Notes for cooks

  • Atlantic wolffish is sometimes sold under the name “ocean catfish” or “wolf fish” at fish markets. Ask the fishmonger to confirm the species.
  • The fillets are naturally thick and hold together well, so they are forgiving for pan-searing and grilling. Avoid overcooking, as the flesh can become dry.
  • If Atlantic wolffish is unavailable, substitute monkfish, halibut, or firm-fleshed cod.
