| Summary: | Master's thesis in Energy, Environment and Society Though 70 % of the earth’s surface is covered by water, but just 2 % of all the foods come from the sea. Increase in population necessitates using sustainable solution is necessary in order to increase production and decrease mortality of fishes in farms. The fish industry in Norway is an old and specific attention is paid to fish aquaculture and fish industry. The salmon lice (Lepeophtheirus salmonis) infesting Atlantic salmon (Salmo salar) in the sea water phase is one of the major issues for the Norwegian aquaculture. To obtain health and welfare of the farmed Atlantic salmon, different innovative treatment methods are being used for controlling the sea lice.
