  2. 2. Fine stream wood effects on drift and brown trout (Salmo trutta) growth and behaviour

    Detta är en avhandling från Karlstad University Press

    Författare :Åsa Enefalk; Karlstads universitet.; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; stream fish; wood; salmonid; trout; aquatic invertebrates; behaviour; sheltering; Biology; Biologi;

    Sammanfattning : Stream ecosystems and their riparian zones have previously been regarded as two different ecosystems, linked through numerous reciprocal subsidies. Today, ecologists agree that the stream and the riparian zone should be regarded as one system, the stream-riparian ecosystem, which is characterised largely by the subsidies between land and water.

  4. 4. Behavioural and Neuroendocrine Effects of Stress in Salmonid Fish

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Øyvind Øverli; Uppsala universitet.; [2001]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Aggression; Behaviour; Brain; Coping; Cortisol; Dominance; Dopamine; Feeding; Hierarchy; Norepinephrine; Responsiveness; Serotonin; Utvecklingsbiologi; NATURAL SCIENCES Biology Organism biology Developmental biology; NATURVETENSKAP Biologi Organismbiologi Utvecklingsbiologi; Developmental Biology; miljömedicinsk utvecklingsbiologi;

    Sammanfattning : 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. LÄS MER

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

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Ken Cheng; Sveriges lantbruksuniversitet.; [2017]
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : 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. LÄS MER
