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

    Master-uppsats, Linköpings universitet/Industriell miljöteknik; 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

  2. 2. Kan musselextrakt (Mytilus edulis) inducera födosök hos omnivoren ruda, Carassius carassius (Linnaeus, 1758)?

    Kandidat-uppsats, Södertörns högskola/Miljövetenskap; Södertörns högskola/Miljövetenskap

    Författare :Ninél Sukovich; Jennifer Backman; [2016]
    Nyckelord :Musselmeal; Olfactory stimulation; Fish feed; Sustainable aquaculture; Sustainable development; Luktstimulerande; Fiskfoder; Musselmjöl; Hållbart vattenbruk; Hållbar utveckling;

    Sammanfattning : Over the last three decades there has been a significant increase in aquaculture production and the demand for farmed fish is predicted to rise further. More fish are being caught to become fishmeal in aquaculture, than for direct human consumption use, while a large number of fish stocks are being depleted. LÄS MER

  3. 3. Musselmjöl : Foderalternativet som renar haven

    Kandidat-uppsats, KTH/Industriell produktion; KTH/Industriell produktion

    Författare :Alexander Nilsson; Johanna Öhrling; [2013]
    Nyckelord :;

    Sammanfattning : Grundtanken med ett ekologiskt lantbruk är att det ska vara självförsörjande och att näringsämnen ska återföras till marken där de skördats. EU har länge strävat efter att 100 % avfodret till ekologiskt fjäderfä ska vara ekologiskt producerat, men målet har flera gånger skjutits upp på grund av bristen på ett proteinfoder som tillgodoser hönans speciella proteinbehov.

  4. 4. Tungmetaller i metabolismen hos värphöns och slaktkycklingar

    Kandidat-uppsats, SLU/Dept. of Animal Nutrition and Management

    Författare :Elin Svedberg; [2010]
    Nyckelord :bly; kadmium; värphöns; slaktkycklingar; metabolism;

    Sammanfattning : Mussel meal is a potential source of protein, with a good composition of amino acids, for laying hens and broiler chickens, and may replace the use of fish meal in organic poultry production. Lead and cadmium are heavy metals which occur in the environment and can be accumulated in mussels. LÄS MER

  5. 5. Domestic feed sources to farmed Arctic Charr (Salvelinus alpinus) : an investigation of nutritional implications and impact on the ecological footprint

    Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

    Författare :Muhamed Muminovic; [2010]
    Nyckelord :zogomycetes; arctic charr; alternative feed ingredients; nutritional implication;

    Sammanfattning : This study presents an overview of recapturing nutrients from Baltic Sea thru mussel farmingand producing mussel meal, detoxification of polluted fish into purified high quality fish mealand oil and introducing microorganisms as waste consumers as well as good protein sourcesfor fish diets. Work on this study is focused on comparing growth performance of test diet,which has been made strictly of domestic (Baltic Sea) protein sources to commercial diet. LÄS MER
