  1. 1. Replacement of fish protein in fish feed : effects on the yeast flora in the gut of Arctic charr (Salvelinus alpinus)

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Hanna Rydmark; [2023]
    Keywords : Microbiota; Saccharomyces cerevisiae; fishmeal; mussel meal; Mytilus edulis; aquaculture;

    Abstract : The aim with this study was to investigate how feeds with different protein sources influence the levels and composition of the yeast flora in the gut of Arctic charr (Salvelinus alpinus). Arctic charr were fed for two weeks on a control diet (C) with fishmeal (FM) or experimental diets with 40% FM replaced by yeast (Saccharomyces cerevisiae) (Y), meal from blue mussel (Mytilus edulis) (M) or a feed with Baltic Sea originated protein; 33% FM, 33% mussel meal (MM) and 33% S.

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

    University essay from SLU/Department of Molecular Sciences

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

    Abstract : 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. READ MORE
