      Arctic charr (<i>Salvelinus alpinus</i> (Linnaeus)) is a stenothermic cold‐water fish, which has been cultured in Northern Europe and North America since the 1980s. The industry has remained relatively small with an annual production between 6000 and 10 000 tonnes, and is still challenged by an unreliable offspring production. This review focuses on offspring production in Arctic charr aquaculture ...
    • Field demonstration of a novel towed, area bubble-plume zooplankton (Calanus sp.) harvesting approach 

      Grimaldo, Eduardo; Leifer, Ira; Gjøsund, Svein Helge; Larsen, Roger B.; Jeuthe, Henrik (Research report; Forskningsrapport, 2010)
      This paper presents field experiment results of using a new technology to harvest copepods (Calanus sp.) in the ocean by bubble upwelling. Two largo-scale bubble rafts, a 21 m2 and a flexible 75 m2 bubble raft with tow parallel and perpendicular sparger elements, respectively, were field tested in areas with high, upper 25-m water column Calanus densities. Measured bubble-driven upwelling velocities ...
