Atlantic Wolffish: The Fish You Are Not Allowed to Release
For forty-four articles every rule in this series ran the same way. The law says what has to go back into the water: minimum size, closed season, and with the halibut even a ceiling. With the Atlantic wolffish, Norway says the opposite. There is no minimum size and no closed season for this fish — and the only provision that touches it at all demands that a dead one be brought ashore. Here, throwing it back is the offence, not the good deed. The pole of this article is therefore: the forbidden release. And the closed season this fish does have, it wrote itself.
One name, three fish — and a fourth that is none of them
First the identification, because few fish names cause more confusion. The one meant here is *Anarhichas lupus* (Linnaeus, 1758) — GBIF usageKey 8006460, rank SPECIES, status ACCEPTED, matchType EXACT, family Anarhichadidae (familyKey 8489), order Perciformes (orderKey 587); in Norwegian gråsteinbit. ⚠️ Three relatives, all resolved against the GBIF API on 3 September 2026: *Anarhichas minor* (2392194), the spotted wolffish (flekksteinbit) — and at 180 cm and 26 kg it is markedly larger than the grey one with its 125 cm; *Anarhichas denticulatus* (2392210), the northern wolffish (blåsteinbit, 138 cm and 32 kg); and *Anarrhichthys ocellatus* (2392219), the Pacific wolf-eel — same family, different genus, and note the double r in the genus name. ⚠️ The most expensive trap, though, sits in everyday language: in German the wolffish is “Seewolf” while the European sea bass is “Wolfsbarsch” — two entirely different animals sharing a word stem. The French “loup de mer” usually means the bass, the Croatian “morski vuk” carries the same ambiguity, and the English trade name “ocean catfish” has nothing whatsoever to do with catfish.
The closed season no legislator wrote
Now the trait that separates this predator from every other in the series. Norway’s Institute of Marine Research states it in a subordinate clause that rearranges an entire fishing plan: “Frå oktober til mai skifter dei ut tennene og sluttar då å beite” — from October to May the wolffish replaces its teeth and stops feeding while it does so. For seven months it voluntarily lays down its weapon. ⚠️ From which follows the most practical sentence in this article: the wolffish does have a closed season — it simply is not written in a statute book but in its jaw. Anyone targeting it in winter is targeting an animal that currently has nothing to bite with. What it eats when it does eat fits the same picture: “Pigghudar (kråkebollar), muslingar, sniglar og krabbar” — sea urchins, mussels, snails, crabs. This is a predator that does not hunt fish but cracks shells; its dentition is a tool that wears out, which is exactly why it has to be renewed. The rest of the biology follows the same logic: a maximum of 125 cm and 20 kg, a lifespan of 20 to 25 years, spawning “over fleire månader frå vår til haust” close to the coast, “i fjordar og vågar frå 50 til 150 meters djup”, with the eggs glued “som ein ball til ein steinete sjøbotn”. And the grey wolffish is “mykje meir stasjonær” than its relatives — it barely migrates. For you that means: a wolffish spot stays a wolffish spot for years.
What the law says — and what it does not
Now the legal position, and it is shorter than everyone assumes. Norway’s høstingsforskriften lists thirty-four numbered species under § 47 “Minstemål”, from “1. Blåkveite 45 cm” to “34. Ål” — wolffish appears under no number at all. Nor does the closed-season provision (§ 39), which covers halibut, monkfish and redfish, mention it. So there is neither a minimum size nor a closed season for this fish. ⚠️ What there is, is the landing obligation in § 51: “All fangst skal føres i land” — all catch must be brought ashore. Two exceptions: letter b exempts “lovlig fangst som er levedyktig når den slippes på sjøen”, a lawfully taken fish that is viable when released. And letter c permits dead or dying catch to be discarded — but only for species not on the list that follows. On that list stand Blåsteinbit, Flekksteinbit and Gråsteinbit by name, all three. Which gives you the whole rule: a viable wolffish may go back. A dead or dying one must come with you. Not may — must. And that is why with this fish the decision falls during the fight, not on deck.
- It is a summer fish by anatomy, not by regulation. The tooth replacement runs from October to May, and it does not feed while it lasts. The usable window comes afterwards. A northern trip that puts the wolffish on the target list in January is planning against the animal’s jaw.
- Site fidelity is your best chart. The grey wolffish barely migrates. Rocky ground, urchin beds, 50 to 150 metres in fjords and bays — find a spot and you have it for years. Record it rather than trusting your memory.
- Decide before you land it, not after. Viable goes back, dead or dying comes ashore: both are duties, not choices. Hooking gently and deciding quickly keeps both routes open.
- No minimum size does not mean “keep everything”. The real ceiling sits in an entirely different regulation — the export rule. It limits not what you catch but what you take home.
- Export depends on the operator, not on the fish. Without documentation from a tourist fishing business entered in the Norwegian register, nothing at all crosses the border. Whether a provider is on that register is a question that belongs before the booking, not at customs.
- Respect the jaw on deck too. This mouth cracks sea urchins and mussels. Gloves, pliers, control the head, never reach into the jaws — and a fish meant to go back is never held by the lower jaw.
And now the paperwork, because this article stands or falls on it. The catch rules live in the høstingsforskriften (Forskrift om gjennomføring av fiske, fangst og høsting av viltlevende marine ressurser, FOR-2021-12-23-3910, Lovdata). § 47 “Minstemål” lists 34 species; wolffish is not among them. § 51 “Ilandføringsplikt” opens with “All fangst skal føres i land” and, in letter c, exempts “død eller døende fangst av andre arter enn:” — the list that follows names Blåsteinbit, Flekksteinbit and Gråsteinbit explicitly. ⚠️ The second regulation is the one most fishing trips come to grief on: FOR-2006-06-01-570 (“Forskrift om utførselsregulering av fisk og fiskevarer fra sportsfiske”), last amended with effect from 1 January 2026. Its § 2 opens with a prohibition: “Det er ikke tillatt å føre ut av landet fisk eller fiskevarer” — fish from sport fishing may in principle not be exported. It is permitted only to someone who can document that the catch was made “i regi av en turistfiskevirksomhet som er registrert i Fiskeridirektoratets register”, that is, under a registered tourist fishing business; then the allowance is “15 kg inntil to ganger i løpet av 2026 og 10 kg inntil to ganger i løpet av hvert kalenderår fra og med 2027” — 15 kg up to twice during 2026, and from 2027 only 10 kg twice a year. Whoever exports must be at least 12 years old, and the documentation must carry name, date of birth and address, the business with its organisation number, the period of stay and of fishing, the date of issue and a signature. § 1 makes clear that salmon, trout, char and freshwater fish fall outside this regulation. ⚠️ Two limits this article will not paper over: these are Norwegian rules — Iceland, the Faroes, Greenland, Canada and EU waters regulate wolffish differently. And regulations change; the reduction from 15 to 10 kg on 1 January 2027 is already in the text. Check the version in force before you travel, not this article.
Not the size — the direction
With this predator what decides is not how big the fish is but which way the rule points — and whether you are fishing in the right half of the year. A wolffish day is therefore never only a question of the spot: it is a question of month, ground and decision — and alongside that, of everything which changes by the hour: water temperature, wind, air pressure, tide, current and light phase. That is exactly what the StrikeAhead app is built for: it reads your water with bite windows, weather and marine data, chart and depth contours, and it learns from your catches, so you fish the moment instead of guessing it. And because on a foreign coast half the answer lies in knowing which stony ground in the fjord holds fish and which operator may legally let you take one home, the second part is the shortcut — that knowledge is on no chart, it sits in someone’s head. The app tells you when. StrikeAhead Pathfinder tells you with whom: our curated directory of fishing guides and skippers — every expert personally vetted, licence and insurance checked before listing, profiles built from real, verified catches in the StrikeAhead logbook rather than from advertising photos, no paid ranking, and no booking fee for you as an angler.
