  1. 11. Metagenomic insights into AMR distributions in freshwaters and soils

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Jay Håkansson; [2023]
    Nyckelord :AMR; metagenomics; freshwater; microbial ecology; soil; antimicrobial resistance;

    Sammanfattning : Antimicrobial resistance (AMR) is rapidly becoming a public health issue, as more and more infectious bacteria become resistant to our known antibiotics. Suggested reasons for the proliferation of these strains are misuse and overuse of antimicrobials, especially on an industrial level, in agriculture, livestock and aquaculture. LÄS MER

  3. 12. Effect of a plant-derived nutraceutical on the tolerance of axenically-cultured Artemia towards abiotic or biotic stressor

    Master-uppsats, SLU/Dept. of Animal Breeding and Genetics

    Författare :Ahumuza Allan Castro; [2023]
    Nyckelord :Artemia; Hsp70; Vibrio campbellii; plant extract; aquaculture; abiotic stressor;

    Sammanfattning : Aquaculture is one of the fastest-growing food-production industries worldwide accounting for almost half of fish used for human consumption. Super-intensive, intensive, and semi-intensive farming practices used to produce large farm fish are increasing the frequency of disease outbreaks which is a major problem affecting sustainable aquaculture growth.

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

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

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

    Sammanfattning : 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.

  5. 14. Stress vid bedövning av öring (Salmo trutta)

    Kandidat-uppsats, SLU/Dept. Of Aquatic Resources

    Författare :Ella Andersson; [2023]
    Nyckelord :fisk; stress; bedövning; kortisol; öring;

    Sammanfattning : Vattenbruk är i Sverige en allt växande marknad med stor potential, både för att bevara sårbara fiskpopulationer och för att producera hållbara animaliska livsmedel. I takt med att fler fiskar odlas för forskning, konsumtion och utsättning ökar behovet av bra och etisk djurhållning. LÄS MER

  7. 15. Sustainability assessment on different crops for aquaponics : an evaluation table for growing crops using wastewater from juvenile Atlantic salmon in RAS

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

    Författare :Elísabet Jónsdóttir; [2023]
    Nyckelord :Aquaponics; RAS; MCDA; Atlantic salmon Smolt; hydroponics; Sustainability; Earth and Environmental Sciences;

    Sammanfattning : Aquaculture is an expanding industry, supplying closer to 50% of the total fish consumption. Commercialized fish production faces sustainability challenges which are important to address. Aquaponics uses wastewater from aquaculture to grow plants using hydroponics. LÄS MER
