  1. 1. 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.

  3. 2. Results Measurement of Livelihood Interventions in the Humanitarian Field, using a Sustainable Livelihoods Framework (SLF) to analyze the Economic Rate of Return (ERR) of an income-generating activity (IGA) project in a post-disaster setting, in San Andres Osuna, Guatemala

    Master-uppsats, Uppsala universitet/Teologiska institutionen

    Författare :Olof Hörmander; [2023]
    Nyckelord :aquaponic fish tanks; results measurement; humanitarian work; development; sustainability; livelihoods; sustainable livelihoods framework SLF ; Economic Rate of Return ERR ;

    Sammanfattning : There is limited evidence-based data on income-generating interventions, both within thehumanitarian and the development field. Nevertheless, there is a growing and unavoidable nexus between the two fields, and therefore also, within their methodologies for measuring project intervention results, as well as their success rates.

  4. 3. Evaluation of filter and extraction kits for eDNA-based quantification of Northern pike density

    Master-uppsats, SLU/Dept. Of Aquatic Resources

    Författare :Ofir Svensson; [2021]
    Nyckelord :Blood and Tissue; Chelex 100; cellulose nitrate membrane filter; COI; extraction kit; filter; glass microfiber filter; pike; PowerWater; quantitative eDNA;

    Sammanfattning : Multi-mesh gillnets are the most common gear in Swedish fish monitoring programs. The method works for many fish species but has limitations. LÄS MER

  5. 4. Beteendeeffekter av antidepressivt läkemedel på abborre (Perca fluviatilis) : socialt och aktivt beteende undersökts genom att kombinera behandlingar med oxazepam, temperatur och predationstryck

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

    Författare :Oskar Karlsson; Svante Knutsen; [2020]
    Nyckelord :antidepressiva läkemedel; oxazepam; abborre;

    Sammanfattning : Användandet av antidepressiva och ångestdämpande läkemedel, som ex. oxazepam, ökar i samhället vilket kan leda till höga halter i våra vattendrag. Tidigare studier har visat att abborrar som blir utsatta för miljörelevanta koncentrationer av oxazepam ändrar sitt beteende. LÄS MER

  7. 5. Behavioral Effects of Amyloid Precursor Protein beta Mutation in zebrafish

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Joynab Sultana; [2020]
    Nyckelord :;

    Sammanfattning : Amyloid precursor protein beta (βAPP) plays an important role in the pathogenesis of Alzheimer’s disease. An appb mutant strain of zebrafish has been previously generated and has shown increased boldness. LÄS MER
