  1. 1. Evaluating the effects of climate change on Arctic char : including impacts of brown trout competition

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

    Författare :Ola Carlström; [2023]
    Nyckelord :arctic char; brown trout; climate change; diet; habitat use; temperature;

    Sammanfattning : Climate change is predicted to increase the average global temperature with 1.5 °C between 2030 and 2052. The areas that are most vulnerable for climate change are the arctic regions. Arctic char (Salvelinus alpinus) is a cold-water salmonid species with the most northern distribution of all freshwater fish species. LÄS MER

  3. 2. 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

  5. 4. Effects of refuge availability on growth and survival of YOY Arctic char (Salvelinus alpinus)

    L3-uppsats, SLU/Dept. Of Aquatic Resources

    Författare :Per Nilsson; [2006]
    Nyckelord :Arctic char; growth; predation; refuge; yoy; cannibalism; survival; shelter;

    Sammanfattning : Risk of predation induces behavioural responses in prey, such as decreased activity and avoidance of risky habitats. Sheltering by prey in low risk habitat not only constrains the physical area but also the accessibility of resources. Hence, variation in refuge availability affects the performance of refuging individuals. LÄS MER
