    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Ola Carlström; [2023]
    Keywords : arctic char; brown trout; climate change; diet; habitat use; temperature;

    Abstract : Climate change is predicted to increase the average global temperature with 1.5 °C between 2030 and 2052. The areas that are most vulnerable for climate change are the arctic regions. Arctic char (Salvelinus alpinus) is a cold-water salmonid species with the most northern distribution of all freshwater fish species. READ MORE

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

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

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

    Abstract : 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.

    Author : Mattias Melin; [2021]
    Keywords : Habitat availability; juvenile brown trout; stream size; population structure;

    Abstract : The productivity or availability of juvenile habitats have theoretically been shown to determine size distributions of adult individuals and population abundance. Brown trout (Salmo trutta) is a species where adults may inhabit lakes and use connected streams for spawning and as nursery habitats for juveniles. READ MORE
