      Oil-adjuvanted vaccines reduce long-term growth in farmed Atlantic salmon Salmo salar, possibly via an increase in metabolic rate due to the energetic demands of the immune system. We tested this hypothesis by comparing ...

    • No room for dessert: A mechanistic model of prey selection in gut-limited predatory fish 

      Fall, Johanna Jennifer Elisabeth; Fiksen, Øyvind (Journal article; Peer reviewed, 2019)
      Predatory fish structure communities through prey pursuit and consumption and, in many marine systems, the gadoids are particularly important. These predators have flexible feeding behaviours and often feed on large prey ...

      Top marine predators, such as odontocetes, pinnipeds, and seabirds, are known to forage around fishing boats as fishermen aggregate and/or discard their prey. Recently, incidents of humpback whales interacting with fishing ...

    • Nonlinear crosstalk in broadband multi-channel echosounders

      Distortion of acoustic wave caused by nonlinear propagation transfers acoustic energy into higher harmonics of the transmitted signal. When operating several broadband echosounders with non-overlapping frequency bands to ...

    • Non‐linearity in interspecific interactions in response to climate change: cod and haddock as an example 

      Durant, Joel Marcel; Ono, Kotaro; Stenseth, Nils Christian; Langangen, Øystein (Peer reviewed; Journal article, 2020)
      Climate change has profound ecological effects, yet our understanding of how trophic interactions among species are affected by climate change is still patchy. The sympatric Atlantic haddock and cod are co‐occurring across ...

    • Nordic Blue Carbon Ecosystems: Status and Outlook
