  4. 2. Migration and quality of landlocked Atlantic salmon smolt : Implications for conservation and management

    Author : Johnny R Norrgård; Eva Bergman; Larry A Greenberg; Monika Schmitz; Martyn Lucas; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; acoustic telemetry; hatchery; life history; migration mortality; regulated rivers; Salmo salar; salmon; smolt; trout; Biology; Biologi;

    Abstract : Atlantic salmon Salmo salar has a complex life cycle, including long migrations and habitat shifts for both juveniles and adults. As such, salmon populations are vulnerable to habitat degradation and fragmentation along their migratory routes. READ MORE

  5. 3. Conservation of landlocked Atlantic salmon in a regulated river : Behaviour of migratory spawners and juveniles

    Author : Anna Hagelin; Eva Bergman; Fleming Ian; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Atlantic salmon; conservation; migration; spawning; hydropower; competition; juveniles; brown trout; hatchery reared; fallback; delay; Biology; Biologi;

    Abstract : Hydropower dams represent one of the major threats to river ecosystems today. The dams block migratory routes in many rivers, which is problematic for migratory fish species. Trap-and-transport may be an alternative to fish passage solutions, as a strategy to compensate for lost river connectivity. READ MORE

  6. 4. MHC and genomic diversity in Atlantic salmon (Salmo salar L.)

    Author : Jakob Lohm; Biologiska institutionen; []
    Keywords : 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;

    Abstract : 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.). READ MORE

  7. 5. Atlantic salmon in regulated rivers : Migration, dam passage, and fish behavior

    Author : Daniel Nyqvist; Larry Greenberg; Theodore Castro-Santos; Olle Calles; Scott Hinch; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fish migration; fish passage; downstream migration; kelt; smolt; Biology; Biologi;

    Abstract : Hydropower dams block migration routes and disrupt longitudinal connectivity in rivers, thereby posing a threat to migratory fish species. Various fish passage solutions have been implemented to improve connectivity with varying success. READ MORE
