The Kelp Cultivation Potential in Coastal and Offshore Regions of Norway
We have evaluated the cultivation potential of sugar kelp (Saccharina latissima) as a function of latitude and position (near- and offshore) along the Norwegian coast using a coupled 3D hydrodynamic-biogeochemical-kelp model system (SINMOD) run for four growth seasons (2012-2016). The results are sp...
Technology development for up-scaling of seaweed biomass production
Taredyrking kan være med på å redde klimaet
Performance measures and models for open-water integrated multi-trophic aquaculture
Qualifying and quantifying nutrient flows within open‐water Integrated Multi‐Trophic Aquaculture (IMTA) systems is necessary to determine transfer efficiencies and to assess overall system performance. There are numerous empirical performance metrics, such as spatially defined growth and nutrient se...
Microalgae in aquaculture regions: Friend and foe
The potential for upscaling kelp (Saccharina latissima) cultivation in salmon-driven integrated multi-trophic aquaculture (IMTA)
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 composition of the kelp Saccharina latissima in salmon-driven IMTA, and to asse...
Kelp industrial production: Potential impacts on coastal ecosystems
Spatio-temporal dynamics in the dissolved nutrient waste plume from Norwegian salmon cage aquaculture
The aim of this study was to define the waste plume dynamics around a salmon farm in Norway. Systematic water sampling and numerical modeling were implemented to define nutrient concentrations in the upper water column at long-term (seasonal) and short-term (between and within days) time scales.
