   Author : Siri Samuelsson; [2022]
   Keywords : Recirculating aquaculture system; renewable electricity; Feed Conversion Ratio; environmental impact; freshwater eutrophication; climate change; land use; cumulative energy use; acidification; Earth and Environmental Sciences;

   Abstract : Today the future supply of seafood is threatened due to human activities which, among other things, has led to overfishing. However, more environmental friendly initiatives of producing seafood have emerged, such as Recirculating Aquaculture Systems (RASs). READ MORE

3. 12. Fatty acid composition in Arctic char (Salvelinus alpinus) fed with red yeast biomass : a comparison between large and small specimens

   University essay from SLU/Department of Molecular Sciences

   Author : Sofia Jacobsson; [2022]
   Keywords : Fatty acid composition; lipid content; oleaginous yeast; Arctic char Salvelinus alpinus ; aquaculture;

   Abstract : Oleaginous yeast has shown to be a promising alternative to replace vegetable oils in fish feed. A problem in aquaculture is that different growth rates can be observed among farm-raised fish, supressing the productions full potential. When different growth rates are observed, it can be questioned if the fish assimilate the feed to the same extent. READ MORE

   Abstract : Victoria Persson Abstract Mussel cultivation is a sustainable type of food production that may help mitigate the nutritional needs of a future world population of 10-12 billion in 2100. The demand for mussels on the French market is increasing but the production is saturated due to a lack of space for expanding the cultivation close to shore. READ MORE
