2. “Sailbuoy for krill” – a concept for autonomous commercial and scientific monitoring of the krill fishing in Antarctica

   Abstract:  Science based management of krill suffers from limitation of time-space information in ... distribution dynamics. Similarly, the industry burns unnecessary amounts of oil in long range searching of ... fishable biomass due to lack of density distribution information. In this paper, we demonstrate that new ... – science partnership in collecting environment and krill distribution data independent of vessel ...

5. Modelling egg and larval transport of Antarctic toothfish (Dissostichus mawsoni) in the East Antarctic region: preliminary result using satellite data

   larval transport of the Antarctic Toothfish in the East Antarctic region. This paper presents the ... observed in the experiment A-1, the majority of particles were advected eastward in the experiment A-2. A ... significant difference is that some particles reached southern shelf-slope zone (nursery ground) in the ... experiment A-2 because of effects of temporal eddy activities.
