  2. 6. Behavioural and Neuroendocrine Effects of Stress in Salmonid Fish

    Author : Øyvind Øverli; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Aggression; Behaviour; Brain; Coping; Cortisol; Dominance; Dopamine; Feeding; Hierarchy; Norepinephrine; Responsiveness; Serotonin; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; Developmental Biology; miljömedicinsk utvecklingsbiologi;

    Abstract : Stress can affect several behavioural patterns, such as food intake and the general activity level of an animal. The central monoamine neurotransmitters serotonin, dopamine, and norepinephrine are important in the mediation of both behavioural and neuroendocrine stress effects. READ MORE

  4. 7. Metabolites in fish and humans as a response to different food ingredients : a metabolomics approach

    Author : Mathilde Brunel; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The main objective of this thesis was to evaluate metabolomics changes in humans and fish as a response to food/feed consumption. To alleviate the environmental impact of animal production and maximize the use of resources, the valorization of meat by-products might be an attractive alternative.

  5. 8. Metabolomics as a tool to evaluate salmonid response to alternative feed ingredients

    Author : Ken Cheng; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Aquaculture has largely expanded in the last decades to satisfy the growing market demands for fish products. Fishmeal and fish oil, which are traditionally used in salmonid feeds, are becoming unsustainable. Development of aquafeeds based on alternative ingredients are needed to overcome the ecological challenges. READ MORE

  6. 9. Improved Assessment in Environmental Monitoring of POPs : Using monitoring data from the aquatic ecosystem and human milk

    Author : Elisabeth Nyberg; Anders Bignert; Jochen Mueller; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Environmental monitoring; temporal trends; power analysis; sampling strategy; PCBs; DDTs; HCHs; HCB; PCDD Fs; fish; bird eggs; blue mussels; human milk; miljökemi; Environmental Chemistry;

    Abstract : The thesis deals with several aspects of monitoring of persistent organic contaminants (POPs) in biological matrices, for example choice of sample, sampling design, and statistical treatment of data both for temporal and spatial trends and for compliance towards a set target value. The efficiency has been evaluated through statistical power analyses. READ MORE
