    Author : Sofia Bjarheim; [2024]
    Keywords : Radionuclide; Marine Environment; Blue Mussels; 14C; Nuclear Power Plant; Physics and Astronomy;

    Abstract : Carbon-14 (14C) is one of the most important contributors to the collective effective dose of the public due to radioactive releases from nuclear power plants. However, the discharge of 14C from nuclear power plants (NPPs) into water has not been measured previously. READ MORE

  3. 2. Compilation of life cycle assessments of cultivated blue mussels : recalculation of the inventory assessments

    University essay from SLU/Department of Molecular Sciences

    Author : Elisabet Runesson; [2020]
    Keywords : LCA; Blue mussels; sustainability; production;

    Abstract : With a growing world population there is an increased demand of sustainable and nutritious food. There is not much more land to farm on whether for food or for feed for livestock. Aquaculture increases more than any other production method, however there is still often a need for feed. READ MORE

  4. 3. Baltic blue mussel (Mytilus edulis L.) and black soldier fly (Hermetia. illucens) combined with pea protein concentrate as protein sources in feed for rainbow trout (Oncorhynchus mykiss)

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Xiaoqing Cui; [2019]
    Keywords : aquaculture; rainbow trout; Baltic blue mussel; black solider fly larvae; digestibility; protein; fishmeal replacement;

    Abstract : A feeding trial was conducted for 9 weeks to test the growth performance, nutrient retention and digestibility in rainbow trout (Oncorhynchus mykiss) in order to assess the potential of Baltic blue mussel meal (Mytilus edulis L) and black solider fly larvae (Hermetia illucens) meal as protein sources. The dietary treatments consisted of one control diet based on high quality fishmeal, one control diet based on pea protein concentrate for testing dietary palatability and two fishmeal-free experimental diets where approximately 20% of the crude protein from the fishmeal was replaced with the protein from either de-shelled blue mussel meal or larvae meal on a dry matter basis.

    Abstract : Flounder, Platichthys flesus, is considered to be an important predator on blue mussels, Mytilus edulis, in the Baltic Sea. The purpose of this study was to investigate if flounder diet, i.e. blue mussels, could have an impact on the relationship between weight and length of flounders, i. READ MORE

  6. 5. Sustainable use of Baltic Sea natural resources based on ecological engineering and biogas production : System analysis and case study Trelleborg

    University essay from KTH/Industriell ekologi

    Author : Sara Karlsson; [2009]
