    • Extent and ecological importance of escape through spawning in sea-cages for Atlantic cod 

      Uglem, Ingebrigt; Knutsen, Øyvind; Kjesbu, Olav Sigurd; Hansen, Øyvind J; Mork, Jarle; Bjørn, Pål Arne; Varne, Rebekka; Nilsen, Rune; Ellingsen, Ingrid H.; Dempster, Timothy David (Journal article; Peer reviewed, 2012-11-14)
      The culture of certain fish species to sizes at which they can reproduce has led to the escape of fertilised eggs or ‘escape through spawning’. To investigate the extent and ecological importance of spawning in sea-cages ...

    • High host densities dilute sea lice Lepeophtheirus salmonis loads on individual Atlantic salmon, but do not reduce lice infection success 

      Samsing, Francisca; Oppedal, Frode; Johansson, David; Bui, Samantha; Dempster, Timothy David (Journal article; Peer reviewed, 2014)
      Host density likely plays a key role in host−parasite interactions, but empirical evidence in marine ecosystems remains limited. Classical models predict a positive relationship between host density and parasite infection ...

    • Precision fish farming: A new framework to improve production in aquaculture 

      Føre, Martin; Frank, Kevin; Norton, Tomas; Svendsen, Eirik; Alfredsen, Jo Arve; Dempster, Timothy David; Eguiraun, Harkaitz; Watson, Win; Stahl, Annette; Sunde, Leif Magne; Schellewald, Christian; Skøien, Kristoffer Rist; Alver, Morten; Berckmans, Daniel (Journal article; Peer reviewed, 2017-11-14)
      Aquaculture production of finfish has seen rapid growth in production volume and economic yield over the last decades, and is today a key provider of seafood. As the scale of production increases, so does the likelihood ...

    • Proxy Measures of Fitness Suggest Coastal Fish Farms Can Act as Population Sources and Not Ecological Traps for Wild Gadoid Fish 

      Dempster, Timothy David; Sánchez-Jerez, Pablo; Fernandez-Jover, Damian; Bayle-Sempere, Just; Nilsen, Rune; Bjørn, Pål Arne; Uglem, Ingebrigt (Journal article; Peer reviewed, 2011-01-17)
      Background: Ecological traps form when artificial structures are added to natural habitats and induce mismatches between habitat preferences and fitness consequences. Their existence in terrestrial systems has been documented, ...
