• Automatic interpretation of otoliths using deep learning 

      Moen, Endre; Handegard, Nils Olav; Allken, Vaneeda; Albert, Ole Thomas; Harbitz, Alf; Malde, Ketil (Journal article; Peer reviewed, 2018)
      The age structure of a fish population has important implications for recruitment processes and population fluctuations, and is a key input to fisheries-assessment models. The current method of determining age structure ...
    • Growth and formation of annual zones in whole otoliths of Greenland halibut, a slow-growing deep-water fish 

      Albert, Ole Thomas (Journal article; Peer reviewed, 2016-03-16)
      There is currently no generally agreed and validated method for age estimation of Greenland halibut (Reinhardtius hippoglossoides) from otoliths, and ageing of intermediate sized individuals of this deep-water flatfish is ...
    • Highly mixed impacts of near-future climate change on stock productivity proxies in the North East Atlantic 

      Kjesbu, Olav Sigurd; Sundby, Svein; Sandø, Anne Britt; Alix, Maud; Hjøllo, Solfrid Sætre; Tiedemann, Maik; Skern-Mauritzen, Mette; Junge, Claudia; Fossheim, Maria; Broms, Cecilie; Søvik, Guldborg; Zimmermann, Fabian; Nedreaas, Kjell Harald; Eriksen, Elena; Höffle, Hannes; Hjelset, Ann Merete; Kvamme, Cecilie; Reecht, Yves; Knutsen, Halvor; Aglen, Asgeir; Albert, Ole Thomas; Berg, Erik; Bogstad, Bjarte; Durif, Caroline; Halvorsen, Kim Aleksander Tallaksen; Høines, Åge Sigurd; Hvingel, Carsten; Johannesen, Edda; Johnsen, Espen; Moland, Even; Myksvoll, Mari Skuggedal; Nøttestad, Leif; Olsen, Erik Joel Steinar; Skaret, Georg; Skjæraasen, Jon Egil; Slotte, Aril; Staby, Arved; Stenevik, Erling Kåre; Stiansen, Jan Erik; Stiasny, Martina H.; Sundet, Jan Henry; Vikebø, Frode Bendiksen; Huse, Geir (Peer reviewed; Journal article, 2021)
      Impacts of climate change on ocean productivity sustaining world fisheries are predominantly negative but vary greatly among regions. We assessed how 39 fisheries resources—ranging from data-poor to data-rich stocks—in the ...
    • Lumpsucker (Cyclopterus lumpus) otoliths: dissection, mounting and age-reading 

      Albert, Ole Thomas; Bertelsen, Bernt; Sigurdur T., Jonsson; Pettersen, Ivar H.; Torstensen, Else (Nofima rapportserie, Research report, 2000)
      A workshop was held at Institute of Marine Research, Flødevigen Marine Research Station, Arendal, Norway, 17-19 February 1999, to investigate methodes for age-determination of lumpsucker (Cyclopterus lumpus) from otoliths. ...
    • Migration patterns of Greenland halibut in the North Atlantic revealed by a compiled mark-recapture dataset 

      Vihtakari, Mikko; Elvarsson, Bjarki Pór; Treble, Margaret; Nogueira, Adriana; Hedges, Kevin; Hussey, Nigel E.; Wheeland, Laura; Roy, Denis; Ofstad, Lise Helen; Hallfredsson, Elvar Halldor; Barkley, Amanda; Estevez-Barcia, Daniel; Nygaard, Rasmus; Healey, Brian; Steingrund, Petur; Johansen, Torild; Albert, Ole Thomas; Boje, Jesper (Peer reviewed; Journal article, 2022)
      Marine fisheries are often allocated to stocks that reflect pragmatic considerations and may not represent the species’ spatial population structure, increasing the risk of mismanagement and unsustainable harvesting. Here ...
    • Pan-Arctic suitable habitat model for Greenland halibut 

      Vihtakari, Mikko; Hordoir, Robinson; Treble, Margret A; Bryan, Meaghan D.; Elvarsson, Bjarki; Nogueira, Adriana; Hallfredsson, Elvar H.; Christiansen, Jørgen Schou; Albert, Ole Thomas (Peer reviewed; Journal article, 2021)
      Deep-sea marine fishes support important fisheries but estimates of their distributions are often incomplete as the data behind them may reflect fishing practices, access rights, or political boundaries, rather than actual ...
    • Pigghåtoktet 2022 - Et samarbeidstokt mellom Havforskningsinstituttet og Måløy Videregående Skole, med opplæringsfartøyet MS Skulebas Senior 

      Andrade Rodriguez, Hector Antonio; Vollen, Tone; Larsen, Torfinn Erling; Albert, Ole Thomas (Toktrapport;2022 - 14, Research report, 2022)
      Pigghå er en datafattig og rødlistet art som historisk har gitt grunnlag for et stort fiskeri med årlige landinger på mer enn 40 000 tonn i mer enn 40 år. Etter langvarig overfiske og etterfølgende bestandssammenbrudd har ...
