  1. 1. 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)

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

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

    Sammanfattning : 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.

  2. 2. 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

  3. 3. 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

  4. 4. Musselmjöl : Foderalternativet som renar haven

    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.

  5. 5. 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
