  1. 1. Effect of a plant-derived nutraceutical on the tolerance of axenically-cultured Artemia towards abiotic or biotic stressor

    Master-uppsats, SLU/Dept. of Animal Breeding and Genetics

    Författare :Ahumuza Allan Castro; [2023]
    Nyckelord :Artemia; Hsp70; Vibrio campbellii; plant extract; aquaculture; abiotic stressor;

    Sammanfattning : Aquaculture is one of the fastest-growing food-production industries worldwide accounting for almost half of fish used for human consumption. Super-intensive, intensive, and semi-intensive farming practices used to produce large farm fish are increasing the frequency of disease outbreaks which is a major problem affecting sustainable aquaculture growth.

  3. 2. Using microalgae for removing nutrients from RAS aquaculture effluents - a viable strategy? A case study.

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Samuel Karlsson; [2022-07-06]
    Nyckelord :;

    Sammanfattning : The increased global demand for fish has caused a tremendous increase in aquaculture production during the last decade, emphasising the importance of systems with a low climate footprint. One such system is a recirculating aquaculture system (RAS) which is land-based as opposed to traditional open systems. LÄS MER

  4. 3. The contribution of testbeds in sustainable innovation : a case study of aquaponics in Sweden

    Master-uppsats, SLU/Dept. of Economics

    Författare :Maximilian Demmer; [2022]
    Nyckelord :innovation; sustainable innovation; Testbed; experimental innovation; technological innovation systems; diffusion; strategic niche management; circular food production; aquaponics; sweden;

    Sammanfattning : Aquaponics has gained increasing popularity as it offers a more sustainable solution to farm fish and leafy greens sustainably and closer to urban centres. While generally seen as a real potential to improve sustainable food production, the commercialisation of aquaponics globally is though still at its beginnings. LÄS MER

  5. 4. Aquaculture and its effect on the wild fish resource in a Swedish lake : An evaluation of changes in fat content, protein content and trophic niche

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

    Författare :Emmy Nyberg; [2022]
    Nyckelord :Aquaculture; wild fish; fat content; protein content; stable isotopes;

    Sammanfattning : Fish is nutritious and important as a food source for many people. It contains high levels of protein, important omega-3 fatty acids as well as micronutrients. For a sustainable fish consumption, aquaculture is needed but it can affect nearby ecosystems in many ways. LÄS MER

  7. 5. Fatty acid composition in Arctic char (Salvelinus alpinus) fed with red yeast biomass : a comparison between large and small specimens

    Master-uppsats, SLU/Department of Molecular Sciences

    Författare :Sofia Jacobsson; [2022]
    Nyckelord :Fatty acid composition; lipid content; oleaginous yeast; Arctic char Salvelinus alpinus ; aquaculture;

    Sammanfattning : Oleaginous yeast has shown to be a promising alternative to replace vegetable oils in fish feed. A problem in aquaculture is that different growth rates can be observed among farm-raised fish, supressing the productions full potential. When different growth rates are observed, it can be questioned if the fish assimilate the feed to the same extent. LÄS MER
