Wolffish
It cracks open crabs and urchins for a living, and the flavour follows the diet.
Wolffish is a lean, dense North Atlantic fish with pearly white flesh and a tighter flake than cod. Its sweetness is dietary: it lives on crabs, urchins and mollusks, which it crushes with molar-like back teeth. Firm enough to braise or grill, which almost no other lean white fish manages.

Firm enough to braise without falling apart — the one lean white fish that will.
Buy it if
You want a white fish that will not fall apart — in a braise, on a grate, or in a sauce that needs to simmer.
Not a catfish, and not a cod. Anarhichas lupus is its own family entirely. "Ocean catfish" and "seawolf" are market names hung on a fish that looks alarming on the boat and unremarkable on the plate. It carries no scales at all — which is also why it cannot be certified kosher.
The teeth explain the flavour. Wolffish live on the rocky bottom eating crabs, urchins, whelks and clams, and they are built for it: conical front teeth and molars at the back for crushing shell. That diet is where the sweetness comes from, and why people reach for "crab" and "lobster" to describe it rather than "cod".
Density is the reason to buy it. The flake is smaller and more tightly bound than cod's, packed closely enough that the fillet keeps its shape in wet heat. Braise it in a sauce, drop it into a curry, turn it on a grate — all things a cod fillet will not survive. If you have ever lost a piece of fish through the grill grates, this is the fish that fixes that.
Wild-caught, off deep rocky ground. Wolffish is landed, not farmed, from roughly 20 to 500 metres down in the cold North Atlantic — the nooks and boulder fields where its food lives. Most of what reaches the US comes out of Iceland, where the fishery is MSC-certified.
The Pacific one is a different animal. Wolf eel, Anarrhichthys ocellatus, is a relative from the other ocean and is sometimes sold under a confusingly similar name. The wolffish on a US counter is Atlantic, and usually Icelandic.

Wolffish vs Cod
Wolffish gets sold as a cod substitute and marketed as "ocean catfish". It is neither. The difference that decides it in a pan is the flake: cod's is large and loose, wolffish's is small and tight.
| Wolffish | Cod | |
|---|---|---|
| Flake | Small and tightly bound | Large and loose |
| Holds in wet heat | Yes — braises without shredding | No — collapses |
| Fat | Moderate | Lean |
| Best method | Pan-sear, Oven-roast or Braise | Oven-roast, Poach or Deep-fry |

Halibut
Firm, lean and dense enough to sear, roast or grill without breaking up. Costs considerably more.
Cooks like
Lingcod
The Pacific answer to the same problem — lean, white and firm enough to take a grate.
Cheaper
Cod
Mild and lean in the same way, but the big loose flake means it will not survive a braise or a grill.
Common questions
What does wolffish taste like?
Mild and clean, with a sweetness people consistently compare to crab or lobster. That is not marketing — the fish eats crustaceans and shellfish, and the diet shows up in the flesh. The texture reads as meaty rather than flaky.
Is wolffish the same as ocean catfish?
Same fish, different name. It is not a catfish and not related to one. "Seawolf" and "devil fish" come from the same place: the animal's face, not its flavour.
Why does wolffish hold together when cod doesn't?
Its muscle segments are smaller and more tightly bound, so there is less for wet heat and a spatula to pull apart. It is the lean white fish to reach for when a recipe involves liquid, a grate, or any handling at all.
Why isn't wolffish kosher?
Kosher fish need both fins and scales. Wolffish has fins and no scales — the skin is bare — so it does not qualify, however it is prepared.
