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 SciencesSammanfattning : 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
2. Framtidens vattenvård : en kvantifiering av internbelastningen av fosfor i Vansjön och Nordsjön i Norduppland
Kandidat-uppsats, SLU/Dept. of Aquatic Sciences and AssessmentSammanfattning : 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
3. Life Cycle Assessment of Minced Bream : A case study performed in collaboration with Axfoundation
Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : 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.

4. Phenotypic correlates of spawning migration behaviour for roach (Rutilus rutilus) and ide (Leuciscus idus) in the stream Oknebäcken, Sweden.
Kandidat-uppsats, Linnéuniversitetet/Institutionen för biologi och miljö (BOM)Sammanfattning : Migration occurs among many animal species for the purpose of, among other things, finding food or to reproduce. Spawning migration is a form of migration that occurs among many fish species where they move to another site for reproduction. The movement can be obstructed by migration barriers like road culverts. LÄS MER
5. Changes in the fish community in Lake Tåkern, Sweden - a comparison between 1978-1979 and 2019
Master-uppsats, Linköpings universitet/BiologiSammanfattning : Climate changes alter species composition in both aquatic and terrestrial ecosystems. For establishment of species in a fish community, dispersal barriers, habitat structure and interactions between species act as a filter. LÄS MER
