      Atlantic cod (Gadus morhua L.) has formed the basis of many economically significant fisheries in the North Atlantic, and is one of the best studied marine fishes, but a legacy of overexploitation has depleted populations ...
    • Cod, haddock, saithe, herring, and capelin in the Barents Sea and adjacent waters: a review of the biological value of the area 

      Olsen, Erik; Aanes, Sondre; Mehl, Sigbjørn; Holst, Jens Christian; Aglen, Asgeir; Gjøsæter, Harald (Journal article; Peer reviewed, 2009-10-09)
      Cod, haddock, saithe, herring, and capelin are the most important fish species in the Barents Sea and adjacent waters. Ecosystem-based management requires species-specific knowledge of the biological value and vulnerability ...
    • Coincident mass occurrence of gelatinous zooplankton in Northern Norway 

      Knutsen, Tor; Hosia, Aino; Falkenhaug, Tone; Skern-Mauritzen, Rasmus; Wiebe, Peter H.; Larsen, Roger B.; Aglen, Asgeir; Berg, Erik (Peer reviewed; Journal article, 2018)
      In autumn 2015, several sources reported observations of large amounts of gelatinous material in a large north Norwegian fjord system, either caught when trawling for other organisms or fouling fishing gear. The responsible ...
    • Genetic management of mixed-stock fisheries "real-time": The case of the largest remaining cod fishery operating in the Atlantic in 2007-2017 

      Dahle, Geir; Johansen, Torild; Westgaard, Jon-Ivar; Aglen, Asgeir; Glover, Kevin (Journal article; Peer reviewed, 2018)
      Fish stocks represent fundamental units in fisheries management, and their identification, especially in mixed-fisheries, represents one of the primary challenges to sustainable harvest. Here, we describe the first “real-time” ...
    • Improving management decisions by predicting fish bycatch in the Barents Sea shrimp fishery 

      Aldrin, Magne; Mortensen, Bjørnar; Storvik, Geir; Nedreaas, Kjell Harald; Aglen, Asgeir; Aanes, Sondre (Journal article; Peer reviewed, 2011-11-20)
      When the bycatch of juvenile fish within the Barents Sea shrimp fishery is too large, the area is closed to fishing for a certain period. Bycatch is estimated from sampled trawl hauls, for which the shrimp yield is recorded, ...

      The Nature Index (NI) is established to get an overview of the state and development of biodiversity within the major ecosystems of Norway. It includes marine, limnic and terrestrial ecosystems. The aim of the index is to ...
    • Measurement of fish target strength with a split-beam echo sounder 

      Foote, Kenneth G.; Aglen, Asgeir; Nakken, Odd (Journal article; Peer reviewed, 1986)
      Data derived with a 38-kHz split-beam echo sounder have been analyzed to yield target strengths suitable for use with echo integrators. This has required compensation for both thresholding and saturation, since these ...
    • Presisjon ved akustisk mengdeberegning av fisk 

      Aglen, Asgeir (Master thesis, 1979)
    • “Real-time” genetic monitoring of a commercial fishery on the doorstep of an MPA reveals unique insights into the interaction between coastal and migratory forms of the Atlantic cod 

      Johansen, Torild; Westgaard, Jon-Ivar; Seliussen, Bjørghild Breistein; Nedreaas, Kjell Harald; Dahle, Geir; Glover, Kevin; Kvalsund, Roger; Aglen, Asgeir (Journal article; Peer reviewed, 2017)
      With the decline of many of the world’s fisheries, increased regulation, including marine protected areas (MPA), forms an increasingly important role in promoting sustainable resource use. Here, we present a novel “real-time” ...
