    • Biological effects of marine diesel oil exposure in red king crab (Paralithodes camtschaticus) assessed through a water and foodborne exposure experiment 

      Sagerup, Kjetil; Nahrgang, Jasmine; Frantzen, marianne; Larsen, Lars-Henrik; Geraudie, Perrine (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-05-30)
      Shipping activities are expected to increase in the Arctic Seas. Today, the majority of vessels are using marine diesel oil (MDO) as propulsion fuel. However, there is a general lack of knowledge of how cold-water marine species respond to acute exposures to MDO. Arctic red king crabs (Paralithodes camtschaticus) were exposed to mechanically dispersed MDO in a flow-through exposure system for one ...

    • Caligus elongatus and other sea lice of the genus Caligus as parasites of farmed salmonids: A review 

      Hemmingsen, Willy; MacKenzie, Ken; Sagerup, Kjetil; Remen, Mette; Bloch-Hansen, Karin; Imsland, Albert (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-02-24)
      This review was prompted by reports of unusually large numbers of sea lice tentatively identified as <i>Caligus elongatus</i> infesting farmed salmon in northern Norway. Following a brief introduction to the sea lice problem in salmonid aquaculture, the review is divided into a further eight sections. The first is a review of existing information on the life cycle and behaviour of <i>Caligus</i> ...

    • Environmental impacts of aquaculture and coexcisting industries 

      Evenset, Anita; Refseth, Gro Harlaug; Dale, Trine; Arnberg, Maj; Harendza, Astrid; Mikkelsen, Eirik Inge; Iversen, Audun; Sagerup, Kjetil; Striberny, Anja; Izquierdo-Gomez, David; Borgersen, Gunhild; Bjorbækmo, Marit Frederikke Markussen; Pedersen, Kristine Bondo; Eriksen, Katrine; Emaus, Per-Arne; Sparboe, Lars Olav; Robertsen, Roy; Steinsbø, Silje (Research report; Forskningsrapport, 2023)
      This is the final report for the project "Environmental impact of aquaculture and coexisting industries - scope for comprehensive regulation" - "MILJØREG". The project is funded by the Norwegian Fisheries and Aquaculture Industry's research funding. The main goal of the project has been to prepare a broad overview of the knowledge base related to the environmental impact of aquaculture, as well ...

    • POP-cocktails : hangover threats for seabirds? The response of three seabird species to exposure to persistent organic pollutants in the Barents Sea 

      Sagerup, Kjetil (Doctoral thesis; Doktorgradsavhandling, 2009-06-11)
      The overall aim of the thesis was to study immunological effects of pollutants in Barents Sea. The Glaucous gull (Larus hyperboreus), black-legged kittiwake (Rissa tridactyla) and Atlantic puffin (Fratercula arctica) were studied. The apex predatory glaucous gull have high levels of persistent organic pollutants (POPs), while the fish eating black-legged kittiwake and Atlantic puffin are located ...

    • Seasonal ecology in ice-covered Arctic seas - Considerations for spill response decision making 

      Aune, Magnus; Aniceto, Ana Sofia; Biuw, Martin; Daase, Malin; Falk-Petersen, Stig; Leu, Eva; Ottesen, Camilla; Sagerup, Kjetil; Camus, Lionel (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-09-05)
      Due to retreating sea ice and predictions of undiscovered oil and gas resources, increased activity in Arctic shelf sea areas associated with shipping and oil and gas exploration is expected. Such activities may accidentally lead to oil spills in partly ice-covered ocean areas, which raises issues related to oil spill response. Net Environmental Benefit Analysis (NEBA) is the process that the response ...
