Use of bubble flotation to improve copepod fisheries: laboratory studies on the physical and behavioural interactions of Calanus finmarchicus and air bubbles
Jeuthe, Henrik (Master thesis; Mastergradsoppgave, 2008-11-15)The current study presents a novel approach to zooplankton harvest in the ocean, where copepods are lifted through the water column and concentrate them at the ocean surface. There they are harvested with a surface skimmer or shallow trawl. The method can potentially reduce fuel costs and unwanted by-catch compared to a conventional plankton trawl. The optimal bubble size for attachment to Calanus ...
