Getting started

Your first try for Atlantic wolffish

One recommended starting point: drift fishing with bait on the bottom from a boat. More methods are listed under “How to fish”.

  1. 1. Place and time

  2. 2. Tackle

    Hook
    Strong hooks. Alvestad usually uses 4/0–7/0, and Fiskeavisen uses a J-hook in size 4/0.SourcesTackle advice from a source of experience · Applies to all regions4ExperienceAsgeir AlvestadTid for steinbit6ExperienceFiskeavisenHvordan fiske steinbiten fra drivende småbåtAll sources on this page
    Rod and line
    A rod with some backbone, so that you can set a hard strike in the tooth-filled jaws. Alvestad mentions a 15–40 lb rod, and Jakt & Fiske a boat rod that can handle sinkers of 200–500 g, with 0.30–0.45 mm multifilament and a long, thick mono leader.SourcesTackle advice from a source of experience · Applies to all regions4ExperienceAsgeir AlvestadTid for steinbit7ExperienceJakt & FiskeSlik fisker du steinbitAll sources on this page
    Attractors
    Strong colours, spinner blades, squid, rubber tubes or beads. Alvestad believes wolffish like yellow and pink. Jakt & Fiske writes that most people bump the baits on the bottom and use strong colours.SourcesTackle advice from a source of experience · Applies to all regions4ExperienceAsgeir AlvestadTid for steinbit6ExperienceFiskeavisenHvordan fiske steinbiten fra drivende småbåt7ExperienceJakt & FiskeSlik fisker du steinbit8ExperienceAsgeir AlvestadSteinbit takkel (oppskrift steg for steg)All sources on this page

    2. 2Boom. A stiff arm that keeps the bait away from the main line, so the rig does not tangle on the way down.SourceTackle advice from a source of experience · Applies to all regions9ExperienceNormark Norway (elbe.no)Sjøfiske fra båtAll sources on this page
    3. 3Sinker. Attached to the boom, keeps the rig near the bottom.SourceTackle advice from a source of experience · Applies to all regions9ExperienceNormark Norway (elbe.no)Sjøfiske fra båtAll sources on this page

    How to assemble it

    • Attach the boom to the main line and the sinker to the boom.SourceTackle advice from a source of experience · Applies to all regions9ExperienceNormark Norway (elbe.no)Sjøfiske fra båtAll sources on this page

Where

Where to find Atlantic wolffish

Where in the sea Atlantic wolffish livesAtlantic wolffish lives in bottom, from 20 to 60 metres depth.

Anglers most often fish for wolffish at 20–60 metres depth. Alvestad gives 10–60 and 20–70 metres, and Hooked states that it is found mostly down to 50–60 metres. In spring it can stay very shallow.SourcesFishing tip confirmed by 3 independent sources of experience · Applies to all regions4ExperienceAsgeir AlvestadTid for steinbit5ExperienceHooked.noHvordan fiske gråsteinbit – art nummer 7 / 526ExperienceFiskeavisenHvordan fiske steinbiten fra drivende småbåt8ExperienceAsgeir AlvestadSteinbit takkel (oppskrift steg for steg)All sources on this page Highlighted: bottomSourcesFishing tip from a specialist source · Applies to all regions2ResearchHavforskningsinstituttetSteinbit4ExperienceAsgeir AlvestadTid for steinbit5ExperienceHooked.noHvordan fiske gråsteinbit – art nummer 7 / 526ExperienceFiskeavisenHvordan fiske steinbiten fra drivende småbåt7ExperienceJakt & FiskeSlik fisker du steinbitAll sources on this page.

Identification

  • Very powerful jaws and teeth.SourcesFact from a specialist source · Applies to all regions1EncyclopediaStore norske leksikongråsteinbit18EncyclopediaStore norske leksikonsteinbitAll sources on this page
  • Elongated body, flattened from the sides, with an unusually long dorsal and anal fin.SourcesFact from a specialist source · Applies to all regions1EncyclopediaStore norske leksikongråsteinbit18EncyclopediaStore norske leksikonsteinbitAll sources on this page
  • Usually grey-blue with black cross bands.SourceFact from a specialist source · Applies to all regions1EncyclopediaStore norske leksikongråsteinbitAll sources on this page

Size

  • Can reach up to 125 cm and 20 kg, and live for 20–25 years. Store norske leksikon gives up to 150 cm and over 20 kg.SourcesFact from a specialist source · Applies to all regions1EncyclopediaStore norske leksikongråsteinbit2ResearchHavforskningsinstituttetSteinbitAll sources on this page

Diet

  • Sea urchins, bivalves, snails and crabs. The jaw is so powerful that it easily crushes bivalves and sea urchins.SourcesFact from a specialist source · Applies to all regions1EncyclopediaStore norske leksikongråsteinbit2ResearchHavforskningsinstituttetSteinbitAll sources on this page

Life history

  • The Atlantic wolffish is much more stationary than the northern and spotted wolffish, more coastal, and lives in shallower water. It stays in relatively shallow water where the bottom is rocky.SourcesFact from a specialist source · Applies to all regions1EncyclopediaStore norske leksikongråsteinbit2ResearchHavforskningsinstituttetSteinbitAll sources on this page
  • The Atlantic wolffish spawns near the coast, in fjords and coves at 50–150 metres depth. The female lays all the eggs in a cluster or ball on the bottom, and the male guards them until they hatch after several months.SourcesFact from a specialist source · Applies to all regions1EncyclopediaStore norske leksikongråsteinbit2ResearchHavforskningsinstituttetSteinbitAll sources on this page
  • Wolffish change their teeth in winter. The Institute of Marine Research writes that they stop feeding from October to May.SourcesFact from a specialist source · Applies to all regions2ResearchHavforskningsinstituttetSteinbit18EncyclopediaStore norske leksikonsteinbitAll sources on this page

The stock

  • South of StadThe Institute of Marine Research has recommended a catch ban of at least ten years for Atlantic wolffish south of Stad inside the territorial limit, with mandatory release of all catches. The recommendation also applies to recreational fishing. This is a recommendation from the Institute, in response to a request from the Directorate of Fisheries for knowledge support to assess protection.SourceFact from a specialist source · Applies to: South of Stad3ResearchHavforskningsinstituttetHI anbefaler fangstforbud for gråsteinbit sør for StadtAll sources on this page
  • The Institute of Marine Research considers the stock of Atlantic wolffish along the Norwegian coast to be poor, especially in Southern Norway (the North Sea and Skagerrak), where it is widely reduced.SourceFact from a specialist source · Applies to all regions3ResearchHavforskningsinstituttetHI anbefaler fangstforbud for gråsteinbit sør for StadtAll sources on this page
  • The Institute also recommends a biologically based minimum size where fishing for Atlantic wolffish is still allowed, because the species is slow-growing and only becomes sexually mature at 6–7 years.SourceFact from a specialist source · Applies to all regions3ResearchHavforskningsinstituttetHI anbefaler fangstforbud for gråsteinbit sør for StadtAll sources on this page
  • The Atlantic wolffish is a key species in the coastal ecosystem. It keeps the sea urchin population down, and its decline is regarded as a main reason why the kelp forest has been overgrazed in Northern Norway.SourceFact from a specialist source · Applies to all regions3ResearchHavforskningsinstituttetHI anbefaler fangstforbud for gråsteinbit sør for StadtAll sources on this page
  • Along the Norwegian coast there is a lack of data on the state of the stock. Catch statistics suggest that catches north of Stad have been stable since 2000, while the statistics south of Stad may indicate a decline.SourceFact from a specialist source · Applies to all regions1EncyclopediaStore norske leksikongråsteinbitAll sources on this page
  • Northern NorwayIn the Saltstraumen marine protected area, all fishing for wolffish has been prohibited since 26 August 2024.SourceFact from a specialist source · Applies to: Northern Norway18EncyclopediaStore norske leksikonsteinbitAll sources on this page
