Supportive breeders of Atlantic salmon Salmo salar have reduced fitness in nature
Jonsson, Bror; Jonsson, Nina; Jonsson, Marius (Peer reviewed; Journal article, 2019)Wild Atlantic salmon (Salmo salar) are in decline over the entire distribution area, and populations are enhanced by supportive breeding. Parental fish are sampled in rivers, crossed and the offspring reared in hatcheries ... -
Thermal conditions during embryogenesis influence metabolic rates of juvenile brown trout Salmo trutta
Durtsche, Richard D.; Jonsson, Bror; Greenberg, Larry A. (Peer reviewed; Journal article, 2021)The projected climate change and increase in thermal conditions in northern latitudes over the next 60 yr has the potential to alter the metabolic scope and potential fitness of aquatic ectotherms. Here, we experimentally ... -
Thermal Effects on Ecological Traits of Salmonids
Jonsson, Bror (Peer reviewed; Journal article, 2023)Here, I review thermal influences on metabolic rates and aerobic scope; growth; adult body size; and reproductive and behavioural traits, such as tendency and timing of the migration of salmonid fishes. A thermal window ... -
Time and size at seaward migration influence the sea survival of Salmo salar
Jonsson, Nina; Jonsson, Bror (Peer reviewed; Journal article, 2014)Whether time of seaward migration of young Atlantic salmon Salmo salar influences their subsequent survival and growth was investigated in the River Imsa, south-western Norway. Salmo salar were tagged when moving downstream ... -
