  1. 1. The Potential to Target Smaller Sized Baltic Herring to Decrease the Dietary Exposure - an Assessment Based on Dioxin Samples from the Southern Baltic

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Sofie Gustafsson; [2024]
    Nyckelord :Dioxin; PCDD Fs; dl-PCBs; Herring; Baltic; Fishery; Technology and Engineering;

    Sammanfattning : PCDD/Fs and dl-PCBs, or more commonly referred to as dioxin and dioxin like substances are compounds present in our surrounding environment. As some congeners of these have been shown to be toxic, they are regulated under the Stockholm Convention. LÄS MER

  3. 2. The climate impact of fishways : A life cycle assessment of Blyberg’s and Spjutmo’s up- and downstream fishways

    Master-uppsats, Linköpings universitet/Industriell miljöteknik

    Författare :Ellen Lundin; Lovisa Liljenberg; [2023]
    Nyckelord :LCA; life cycle analysis; life cycle assessment; fishways; fish; fish migration; climate impact; technical fishways; co2 equivalents; co2 eq; hydro power; HPP; Sweden; construction; concrete; reinforcement steel;

    Sammanfattning : The Swedish national plan for reapproval of hydropower describes that hydropower plants (HPPs) are required to be reassessed to ensure that modern environmental conditions are set for the permits. Since dams and HPPs create barriers for migrating fish and consequently disfavor biological diversity, one consequence of the national plan is that fishways are being constructed. LÄS MER

  4. 3. More Fish, more Mahasoa? A Quantitative Analysis of Food Security & Poverty Reduction in Rural Small-scale Aquaculture in Madagascar

    Master-uppsats, Lunds universitet/Ekonomisk-historiska institutionen

    Författare :Gianna Laura Angermayr; [2023]
    Nyckelord :Madagascar; Small-scale Aquaculture; Pond Aquaculture; Integrated Rice-Fish Farming; Community Well- being; Poverty Reduction; Food Security.; Business and Economics;

    Sammanfattning : The role of food-producing sectors such as agriculture and aquaculture in the development process is debated and while some consider industrial production to be the answer, others suggest that small-scale production can also make contributions to poverty reduction and food security. This thesis aims to shed light on these relationships by performing quantitative analyses of the small-scale freshwater aquaculture sector in six regions of Madagascar. LÄS MER

  5. 4. Fish Friendly Turbines forDownstream Migration : Literature review and case studies

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Signe Rosenblad; [2023]
    Nyckelord :Downstream passage solutions; downstream migration of fish; small-scale hydropower; eel; trout; Nedströms passagelösningar; nedströms vandring av fisk; småskalig vattenkraft; ål; öring;

    Sammanfattning : As the energy consumption is constantly increasing, the demand of renewable energy is increasing too. Thirtythree percent of the renewable energy production in Europe constitutes of hydropower. Hydropower is animportant energy source as it has stabilizing and storing functions, but it heavily affects biodiversity. LÄS MER

  7. 5. Fiskkonsumtion under och efter graviditet : En kvantitativ enkätstudie

    Kandidat-uppsats, Umeå universitet/Institutionen för kost- och måltidsvetenskap

    Författare :Elsa Christenson; Frida Berg; [2023]
    Nyckelord :Fiskkonsumtion; graviditet; kostråd;

    Sammanfattning : SAMMANFATTNING Bakgrund Graviditeten är en period då många kvinnor lägger till, undviker eller begränsar vissa livsmedel. Fiskkonsumtion under graviditet har många hälsofördelar både för fostret och för mamman. Trots detta tenderar kvinnor att minska sin fiskkonsumtion under graviditeten. LÄS MER
