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

   University essay from SLU/Department of Molecular Sciences

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

   Abstract : 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. READ MORE

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

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

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

   Abstract : 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.

   Author : Manfred Skog; [2020]
   Keywords : Fish community; Shallow lakes; Test-fishing; Establishment of species; Crucian carp; Bream; Winter hypoxia;

   Abstract : 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. READ MORE

5. 4. Natural migration barriers for fish by hydropower plants : methods to assess historic passability. Case studies of migration barriers

   University essay from SLU/Dept. Of Aquatic Resources

   Author : Johansson Anders; [2016]
   Keywords : natural migration barriers; historic passablility; reference connectivity; connectivity; fish; brown trout; eel; hydropower;

   Abstract : Is it necessary to build fishways at all artificial migration barriers to restore and sustain bio-diversity? Hydropower plants have often been built at places where a difference in height has been used to gain more power, leading to the hypothesis that many hydropower dams have been built at natural migration barriers. How are Swedish running waters (not large rivers) assessed with respect to historical passability for fish at natural migration barriers and dams? How does one study a specific location with respect to the historical passability for different fish species? The methodologies that are evaluated in this thesis are relevant and specific information from a habitat mapping from Värmland County, where 2 903 km waterways already have been surveyed. READ MORE

6. 5. Sustainable Resource Use of Common Bream and Roach Catch from Reduction Fishing in Östergötland

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Malin Svensson; [2014]
   Keywords : Sustainable development; Eutrophication; Reduction fishing; Biomanipulation; Waste management;

   Abstract : Nutrient inflows from anthropogenic sources into water systems are causing eutrophication, algal blooms and trophic changes in Swedish lakes and seas. The European water framework directive was implemented to regulate member countries' policies to achieve a good status in surface waters. READ MORE
