    • 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 (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-08)
      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 geographic distributions. We use a simple suitable habitat model based on bottom depth, temperature, and salinity to estimate the potential distribution of Greenland halibut ...

    • Predation on early life stages is decisive for year-class strength in the Barents Sea capelin (Mallotus villosus) stock 

      Gjøsæter, Harald; Hallfredsson, Elvar H.; Mikkelsen, Nina; Bogstad, Bjarte; Pedersen, Torstein (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-10-11)
      Year-class strength of Barents Sea capelin has been monitored closely since the early 1970s and during this ∼45 years period three short periods of almost total recruitment failure leading to three stock collapses have been observed. These events triggered much attention since there was a large commercial fishery for capelin, but also because of observed ecosystem effects attributed to the first of ...
