  1. 1. Reproductive performance of farmed Arctic charr

    Författare :Henrik Jeuthe; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The production of farmed Arctic charr (Salvelinus alpinus) has increased rapidly over the last decade, and the industry is predicted to continue to grow in the coming years. One major bottleneck for this future expansion concerns the supply of viable eggs and juveniles. LÄS MER

  3. 2. Sustainable farming of Arctic charr (Salvelinus alpinus)

    Författare :Hanna Carlberg; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Arctic charr (Salvelinus alpinus L.) is a salmonid that is well adapted to cold waters and is commonly farmed in open net cages. A breeding program has enabled a relatively large production in Sweden, providing a continuous supply of fresh fish to the market. LÄS MER

  5. 4. The decline of great Arctic charr in Lake Vättern : empirical and theoretical analyses of suggested causes

    Författare :Malin Setzer; Tomas Jonsson; Bo Ebenman; Mark C. Emmerson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Naturvetenskap;

    Sammanfattning : Human activity is affecting species and ecosystems all over the world. In aquatic systems negative trends can be seen for many fish stocks and potential consequences of this, for ecosystem structure and functions, are of particular concern. LÄS MER

  7. 5. MHC and genomic diversity in Atlantic salmon (Salmo salar L.)

    Författare :Jakob Lohm; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Djurekologi; cytogenetik; Genetik; cytogenetics; Genetics; nucleotide diversity; isolation-by-distance; DGGE; AFLP; furunculosis; disease resistance; Arctic charr; brown trout; Atlantic salmon; population genetics; genetic variation; Mhc class IIB; Animal ecology;

    Sammanfattning : In this thesis I present studies concerning genomic diversity and genetic heterogeneity as well as the evolution and maintenance of genetic variation at a specific immune defence gene in Atlantic salmon (Salmo salar, L.). LÄS MER
