      macaulay, gavin; Skaret, Georg; Knutsen, Tor; Bergstad, Odd Aksel; Krafft, Bjørn Arne (CCAMLR;WG-EMM-18/12, Research report, 2018)
      The previously presented document at the 2018 ASAM WG meeting (ASAM-18-07) described a design and plans for a synoptic krill acoustic survey in CCAMLR area 48 in 2019. The survey involves the collaborative efforts of Norway, ...
    • Adaptive mass formations in fish shoals founded in conflicting motivation 

      Johnsen, Espen; Skaret, Georg (Journal article; Peer reviewed, 2008-04-21)
      The organising principles behind adaptive collective formations in animals are not well understood. Here we document that persistent vertical hourglass formations occur during the critical spawning period in huge shoals ...
    • An Antarctic krill (Euphausia superba) hotspot - population characteristics, abundance and vertical structure explored from a krill fishing vessel 

      Krafft, Bjørn Arne; Skaret, Georg; Knutsen, Tor (Conference object, 2016)
    • An Antarctic krill (Euphausia superba) hotspot: population characteristics, abundance and vertical structure explored from a krill fishing vessel

      We here present a fitted and partly validated Ecopath with Ecosim model for the Norwegian Sea and Barents Sea. Ecopath mass-balance model parameters were obtained from the literature on Norwegian and Barents Sea organisms ...
    • Antarctic krill and apex predators in the South Orkney Islands area 2011, surveyed with the commercial fishing vessel Saga Sea 

      Krafft, Bjørn A.; Skaret, Georg; Calise, Lucio (Rapport fra Havforskningen;Nr. 6-2011, Working paper, 2011-05)
    • Antarctic krill and apex predators in the South Orkney Islands area 2012, surveyed with the commercial fishing vessel Juvel 

      Skaret, Georg; Krafft, Bjørn A.; Trathan, Phil (Rapport fra Havforskningen;Nr. 9-2013, Working paper, 2013-04)
    • Antarctic krill and ecosystem monitoring survey at South Orkney Islands in 2015, and assessing escape mortality of krill in trawls 

      Skaret, Georg; Krafft, Bjørn A.; Krag, Ludvig A.; Pedersen, Ronald (Rapport fra Havforskningen;9-2015, Working paper, 2015-05)
    • Antarctic krill and ecosystem monitoring survey at South Orkney Islands in 2016 

      Krafft, Bjørn Arne; Skaret, Georg; Krag, Ludvig Ahm; Rustand, Torborg; Pedersen, Ronald (Rapport fra havforskningen;20-2016, Research report, 2016)
      Small scaled Russian exploratory fishing for krill in the Southern Ocean began in the late 1960s. During the 1970s the fisheries increased and annual catches of krill have exhibited a number of fluctuations since the ...
    • Antarctic krill and ecosystem monitoring survey off the South Orkney Islands in 2018
