A new Norwegian bioeconomy based on cultivation and processing of seaweeds: Opportunities and R&D needs
Skjermo, Jorunn; Aasen, Inga Marie; Arff, Johanne; Broch, Ole Jacob; Carvajal, Ana Karina; Christie, Hartvig C; Forbord, Silje; Olsen, Yngvar; Reitan, Kjell Inge; Rustad, Turid; Sandquist, Judit; Solbakken, Roar; Steinhovden, Kristine; Wittgens, Bernd; Wolff, Robert; Handå, Aleksander (Research report, 2014) -
Initial short-term nitrate uptake in juvenile, cultivated Saccharina latissima (Phaeophyceae) of variable nutritional state
Forbord, Silje; Etter, Siv Anina; Broch, Ole Jacob; Dahlen, Vegard Rønning; Olsen, Yngvar (Journal article; Peer reviewed, 2021)To reach the goal of large-scale seaweed cultivation in Norway, new knowledge concerning commercially important species like the kelp Saccharina latissima is essential. This includes fundamental understanding of physiological ... -
Latitudinal, seasonal and depth-dependent variation in growth, chemical composition and biofouling of cultivated Saccharina latissima (Phaeophyceae) along the Norwegian coast
Forbord, Silje; Matsson, Sanna; Brodahl, Guri Ellila; Bluhm, Bodil; Broch, Ole Jacob; Handå, Aleksander; Metaxas, Anna; Skjermo, Jorunn; Steinhovden, Kristine; Olsen, Yngvar (Journal article; Peer reviewed, 2020)The Norwegian coastline covers more than 10° in latitude and provides a range in abiotic and biotic conditions for seaweed farming. In this study, we compared the effects of cultivation depth and season on the increase in ... -
MacroBiomass En kompetansebase for industriell taredyrking
Forbord, Silje; Handå, Aleksander; Broch, Ole Jacob; Arff, Johanne; Dahle, Stine Veronica Wiborg; Fredriksen, Stein; Reitan, Kjell Inge; Steinhovden, Kristine; Størseth, Trond Røvik; Tangen, Karl; Lüning, Klaus (Research report, 2013)MacroBiomass Prosjektet MacroBiomass har hatt som mål å bygge en kompetansebase med fokus på biologiske utfordringer i storskala dyrking av makroalger (tare) til bioenergi. Prosjektet har jobbet med hele produksjonssyklusen ... -
Modelling the cultivation and bioremediation potential of the kelp Saccharina latissima in close proximity to an exposed salmon farm in Norway
Broch, Ole Jacob; Ellingsen, Ingrid H.; Forbord, Silje; Wang, Xinxin; Volent, Zsolt; Alver, Morten; Handå, Aleksander; Andresen, Kjersti; Slagstad, Dag; Reitan, Kjell Inge; Olsen, Yngvar; Skjermo, Jorunn (Journal article; Peer reviewed, 2013)A 3-dimensional hydrodynamic−ecological model system (SINMOD) was used to estimate the full-scale cultivation potential of the brown alga Saccharina latissima in integrated multi-trophic aquaculture (IMTA) with Atlantic ... -
Morfologiske relasjonar til dyrka Saccharina latissima ved tre stasjonar langs Norskekysten
Foldal, Solveig (Master thesis, 2018)Makroalgar har i tusenvis av år blitt brukt til mat og andre føremål over heile verda, og land som Kina, Korea og Japan har ein lang tradisjon for kultivering av tare. I Europa derimot er taren hovudsakleg hausta frå ville ... -
Multiscale modelling of cage effects on the transport of effluents from open aquaculture systems
Broch, Ole Jacob; Pascal, Klebert; Michelsen, Finn Are; Alver, Morten (Peer reviewed; Journal article, 2020)Most Atlantic salmon mariculture operations use open sea cages for the grow out phase. The ultimate fate and effects of the effluents and the possibilities of disease transfer between fish farms are major concerns for ... -
Nutrient fluxes in the Arctic in the present climate regime
Ellingsen, Ingrid H.; Broch, Ole Jacob; Slagstad, Dag (Research report, 2014)The Arctic Ocean (AO) will likely become ice-free in summer within the next two decades. This will change light conditions for primary production. Parts of the AO where primary production is presently light limited will ... -
OC2017 A-200 - Potensialet for dyrking av makroalger i Trøndelag
Broch, Ole Jacob; Tiller, Rachel (Research report, 2017)Rapporten er en utredning om potensialet for storskala dyrking av makroalger i Trøndelag. Dyrking av makroalger både innenfor og utenfor grunnlinjen blir vurdert. De nye forskningsresultatene er basert på simuleringer med ... -
The Potential for Upscaling Kelp(Saccharina latissima) Cultivation in Salmon-Driven Integrated Multi-Trophic Aquaculture (IMTA)
Fossberg, Julia; Forbord, Silje; Broch, Ole Jacob; Malzahn, Arne; Jansen, Henrice M; Handå, Aleksander; Førde, Henny; Bergvik, Maria; Fleddum, Anne Lise; Skjermo, Jorunn; Olsen, Yngvar (Journal article; Peer reviewed, 2018)Integrated multi-trophic aquaculture (IMTA) has the potential of reducing open-cage fish farming impacts on the environment while also introducing new value chains. The aim of this study was to investigate the growth and ...
