  1. 1. A catch-22 scenario in the Swedish food system : –A scientific examination of cyprinid fishingand its management possibilities in Sweden

    Master-uppsats, SLU/Department of Molecular Sciences

    Författare :Peter Andreas Van Berlekom; [2023]
    Nyckelord :Cyprinids; Swedish food supply chain; fisheries management; Complex Adaptive System CAS ;

    Sammanfattning : Cyprinid fish like roach, bream and ide are natural resources in Sweden that were common and consumed in households up to the late 19th century. Due to societal changes during the industrialization cyprinids lost their domestic importance. Today we see an increasing demand for sustainable food sources. LÄS MER

  3. 2. Framtidens vattenvård : en kvantifiering av internbelastningen av fosfor i Vansjön och Nordsjön i Norduppland

    Kandidat-uppsats, SLU/Dept. of Aquatic Sciences and Assessment

    Författare :Caroline Agrillo; Jens Fölster Jens Fölster; [2021]
    Nyckelord :fosfor; internbelastning; eutrofiering; syrebrist; aluminiumbehandling; biomanipulation;

    Sammanfattning : En kvantifiering av internbelastningen av fosfor gjordes i de eutrofierade sjöarna Vansjön och Nordsjön i Norduppland genom fysiokemisk mätning av vattnet och fraktionsanalys samt inkuberingsanalys av sediment. Mycket låga syrehalter mättes under vintern 2021 medan vattnet var övermättat på syre under våren detsamma året. LÄS MER

  4. 3. Life Cycle Assessment of Minced Bream : A case study performed in collaboration with Axfoundation

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

    Författare :Katja Andersson; [2021]
    Nyckelord :Life cycle assessment; LCA; Bream; Abramis brama; Minced bream; Carp cyprinids; Sustainable protein; Livscykelanalys; LCA; Braxen; Abramis brama; Braxenfärs; Karpfiskar; Hållbart protein;

    Sammanfattning : The need for more sustainable protein sources is growing globally due to the significant climate impact from the food system and the estimated population growth. Although vegetarian protein sources have been proven to be sustainable alternatives, there may exist additional resources that currently are not utilized but potentially could contribute as sustainable protein sources.

  5. 4. Arkelstorpsviken i Oppmannasjön - Källor till fosfor och kväve, status och åtgärdsförslag

    Master-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Susann Söderberg; [2016]
    Nyckelord :Eutrophication; catchment area; Arkelstorpsviken; Oppmannasjön; phosphorus; nitrogen; biomanipulation; Earth and Environmental Sciences;

    Sammanfattning : Arkelstorpsviken has experienced severe eutrophication during several decades along with toxic algal blooms that have made the water unsuitable for exposure. While the rest of lake Oppmannasjön has been classified according to biological, physical-chemical and hydromorphological factors, Arkelstorpsviken remains unclassified. LÄS MER

  7. 5. Mellanskarven (Phalacrocorax carbo sinensis) i Krankesjön - Analys av långtidserier av skarvförekomster och fisksamhällets utveckling i kombination med bytesval

    Master-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Jonathan Loive; [2015]
    Nyckelord :Earth and Environmental Sciences;

    Sammanfattning : This study analyzed highly detailed long-term information about occurrence of cormorants (Phalacrocorax carbo sinensis) and the fish community composition in lake Krankesjön, southern Sweden. Moreover, cormorant predation with regards to species and size preference were estimated using data from recovered PIT (Passive Integrated Transponders) tags. LÄS MER
