  1. 1. Can blue mussel shells be used for retrospective 14C-analysis in the marine environment of nuclear power plants?

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

    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

  2. 2. Replacement of fish protein in fish feed : effects on the yeast flora in the gut of Arctic charr (Salvelinus alpinus)

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

    Author : Hanna Rydmark; [2023]
    Keywords : Microbiota; Saccharomyces cerevisiae; fishmeal; mussel meal; Mytilus edulis; aquaculture;

    Abstract : The aim with this study was to investigate how feeds with different protein sources influence the levels and composition of the yeast flora in the gut of Arctic charr (Salvelinus alpinus). Arctic charr were fed for two weeks on a control diet (C) with fishmeal (FM) or experimental diets with 40% FM replaced by yeast (Saccharomyces cerevisiae) (Y), meal from blue mussel (Mytilus edulis) (M) or a feed with Baltic Sea originated protein; 33% FM, 33% mussel meal (MM) and 33% S.

  3. 3. Algal toxins in the Baltic blue mussel (Baltic Mytilus trossulus edulis) : spatiotemporal variations in the Baltic Sea

    University essay from SLU/Dept. Of Aquatic Resources

    Author : Maya Ahlgren; [2021]
    Keywords : algal toxins; Mytilus trossilus edulis;

    Abstract : Algal toxins have been found to bioaccumulate and have a seasonal variation over the summer months in marine biota. This can impact the food web through trophic transfer and the potential of using blue mussels for aquaculture. READ MORE

  4. 4. Copper bioaccumulation in blue mussels and periwinkles from marinas

    University essay from Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

    Author : Tomas Sjökvist; [2019]
    Keywords : Littorina littorea; Mytilus edulis; antifouling paint; invertebrates; biomonitoring;

    Abstract : Copper (Cu) is a heavy metal that is essential for life but toxic at high concentrations. This toxic effect is used on boats to prevent biofouling on boat hulls by painting the hulls with antifouling paint that contain high levels of Cu. The Cu is slowly diffused out in the water and accumulated by animals higher up in the food chain. READ MORE

  5. 5. 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.
