Abstract
With the current rise in the global blue food demand, it is crucial to investigate the current and future production activities and their potential impact on the environment. We are looking at 6 different technologies for salmon aquaculture in Norway with various levels of maturity and market presence: closed, semi-closed, land-based, offshore, submerged, and traditional. The assessment of the sustainability of the novel Norwegian aquaculture production technologies, which are still in the early stages of commercialization and are not yet extensively used, is crucial because Norway is one of the major global exporters of salmon. We are using life cycle assessment (LCA) as the method for estimating for each of the technologies the potential impacts on the climate, environment, and nature related to energy use, direct emissions (feed residues, faeces, pharmaceuticals etc.).
