  1. 1. Effects of summer peaks on brown trout and Atlantic salmon growth and survival in hydropower-regulated Gullspång River

    Kandidat-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Oscar Hallberg; [2023]
    Nyckelord :hydropeaking; hydropower; fish; salmon; salmo salar; salmo trutta; summer; survival; growth; parr; fry; korttidsreglering; vattenkraft; salmonid; salmo salar; salmo trutta; tillväxt; överlevnad; lax; öring;

    Sammanfattning : Daily demands for electrical power are met through sub-daily release of turbined water in the form of hydropeaking. Hydropeaking’s changes to stream flow are listed as a threat to biodiversity in river ecosystems as it causes rapid habitat alteration such as increased depth and velocity, affecting the species living downstream.

  3. 2. Utvärdering av hydraulisk simulering som metod för habitatskattning för lax och öring

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Oscar Axelsson; [2023]
    Nyckelord :Habitat mapping; ecohydraulics; Atlantic salmon; brown trout; habitatkartering; ekohydraulik; lax; öring;

    Sammanfattning : As all of Sweden's hydropower is to be re-examined within a 20-year period, methods are needed to carry out ecological investigations of dammed waterways. The first aim of this thesis is to evaluate whether methods for salmon and trout habitat mapping take all relevant indicators into account. LÄS MER

  4. 3. Effekter av inkuberingstemperatur hos juvenil atlantlax (Salmo salar L.)

    Kandidat-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Oscar Adolfsson; [2018]
    Nyckelord :Climate change; salmon; body shape; parr; Lax; Klimatförändringar; kroppsform; parr;

    Sammanfattning : Rising temperatures, because of climate change, will have major consequences for the world's fish populations, including the Atlantic salmon Salmo salar L. The greatest temperature changes are expected to occur during winter, which will affect S. salar since the eggs are developing during this time of year. LÄS MER
