  1. 1. Mussel farming along the south-Swedish coasts - a possible solution to eutrophication?

    Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :David Trulsson; [2023]
    Nyckelord :Mussel farming; Aquaculture; Spatial suitability analysis; Eutrophication; Baltic Sea; Biology and Life Sciences; Earth and Environmental Sciences;

    Sammanfattning : The concept of mussel farming as a mitigator to nutrient pollution is steadily spreading. The southernmost part of Sweden borders the Baltic Sea where the water quality differs between the costs, however, all are affected by eutrophication. LÄS MER

  3. 2. STARTING FROM THE BOTTOM: USING LOW TROPHIC SPECIES IN SALMON FEEDS. Assessing the environmental performance of novel salmon feeds with LCA .

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Moritz Hempel; [2022-08-30]
    Nyckelord :LCA; Salmon aquaculture; novel feeds; seaweed; blue mussel;

    Sammanfattning : Over the past 30 years, the formulation of salmon feeds has shifted from being based on marine ingredients like fishmeal and fish oil towards more plant-based ingredients. This shift was caused by limited supply of wild fish and general sustainability concerns related to using forage fish for feed, so they were mainly replaced with vegetable-protein. LÄS MER

  4. 3. Is blue mussel farming a potential mitigation tool to combat eutrophication in the Baltic Sea? A synthesis based on stakeholder interviews

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Emilija Zilinskaite; [2019]
    Nyckelord :Sustainable Development; Baltic Sea; Baltic Sea Region; eutrophication; blue mussel farming; circular economy;

    Sammanfattning : The Baltic Sea is the most polluted sea in the world. Its hydrological conditions and ongoing eutrophication are a high threat for marine biodiversity and ecosystems. Additionally, eutrophication has negative effects on the wellbeing of countries and their societies in the Baltic Sea Region (BSR). LÄS MER

  5. 4. Using Blue Mussels as a Tool for Mitigating Eutrophication in the Baltic Sea

    Master-uppsats, Linköpings universitet/Industriell miljöteknik

    Författare :Johanna Ståhle; Linnea Henriksson; [2018]
    Nyckelord :Life cycle analysis LCA ; recycling of nutrients; blue mussels; mussel farm; mussel meal; biogas; compost;

    Sammanfattning : Eutrophication is a consequence of excess nutrients in the water which leads to increased algaegrowth, reduced water transparency and hypoxic bottoms. This is the biggest environmental problemfor the Baltic Sea which recently has resulted in stricter legislations and other initiatives to help theBaltic Sea to recover. LÄS MER

  7. 5. Värdet av musselodlingar som reningsåtgärd i en kostnadseffektiv rening av kväve och fosfor från Östersjön

    L3-uppsats, SLU/Dept. of Economics

    Författare :Martin Lindqvist; [2008]
    Nyckelord :musslor; kväve; fosfor; kostnadseffektivitet; Östersjön;

    Sammanfattning : Övergödning på grund av mänskliga utsläpp av närsalter, främst kväve och fosfor är ett av de allvarligaste miljöproblemen i Östersjön. Blåmusslor lever av att filtrera växtplankton från vattnet och binder därigenom kväve och fosfor. På så sätt bidrar de till att minska övergödningen när de skördas. LÄS MER
