Considering sampling bias in close-kin mark–recapture abundance estimates of Atlantic salmon
Wacker, Sebastian; Skaug, Hans Julius; Forseth, Torbjørn; Solem, Øyvind; Ulvan, Eva Marita; Fiske, Peder; Karlsson, Sten (Peer reviewed; Journal article, 2021)Genetic methods for the estimation of population size can be powerful alternatives to conventional methods. Close-kin mark–recapture (CKMR) is based on the principles of conventional mark–recapture, but instead of being ... -
Does Catch-and-Release Angling Alter the Behavior and Fate of Adult Atlantic Salmon During Upriver Migration?
Lennox, Robert J.; Uglem, Ingebrigt; Cooke, Steven J.; Næsje, Tor; Whoriskey, Frederick G.; Havn, Torgeir Børresen; Ulvan, Eva Marita; Solem, Øyvind; Thorstad, Eva Bonsak (Journal article; Peer reviewed, 2015)To reproduce, Atlantic Salmon Salmo salar return to freshwater rivers and migrate upriver to spawning areas. This migration is the basis for recreational fisheries, which for conservation reasons are increasingly characterized ... -
Effects of episodic exposure to high-pH water on survival of Atlantic salmon eggs and juveniles: Results from laboratory and field Studies
Foldvik, Anders; Holthe, Espen; Bremset, Gunnbjørn; Solem, Øyvind (Peer reviewed; Journal article, 2022)Although effects of acidification on salmonidfish are well studied and documented, effects of episodic high pHhave rarely received attention. In the present study, we investigated effects of high‐pH events on Atlantic ... -
Influence of gear switching on recapture of Atlantic salmon (Salmo salar) in catch-and- release fisheries
Lennox, Robert J.; Diserud, Ola Håvard; Cooke, Steven J.; Thorstad, Eva Bonsak; Whoriskey, Frederick G.; Solem, Øyvind; Havn, Torgeir Børresen; Uglem, Ingebrigt (Journal article; Peer reviewed, 2016)Anglers that release Atlantic salmon (Salmo salar) in recreational fisheries do so with the intention that the fish will survive and contribute to succeeding generations. In some instances, salmon that are released may be ... -
Monitoring presence and abundance of two gyrodactylid ectoparasites and their salmonid hosts using environmental DNA
Fossøy, Frode; Brandsegg, Hege; Sivertsgård, Rolf; Pettersen, Oskar; Sandercock, Brett K.; Solem, Øyvind; Hindar, Kjetil; Mo, Tor Atle (Peer reviewed; Journal article, 2019)Background: Invasive species represent a major challenge for the conservation of biodiversity. The invasive ectoparasitic fluke Gyrodactylus salaris is considered one of the major threats to the Atlantic salmon (Salmo ... -
The effect of catch-and-release angling at high water temperatures on behaviour and survival of Atlantic salmon Salmo salar during spawning migration
Havn, Torgeir Børresen; Uglem, Ingebrigt; Solem, Øyvind; Cooke, Steven J.; Whoriskey, Frederick G.; Thorstad, Eva Bonsak (Journal article; Peer reviewed, 2015)In this study, behaviour and survival following catch-and-release (C&R) angling was investigated in wild Atlantic salmon Salmo salar (n = 75) angled on sport fishing gear in the River Otra in southern Norway at water ... -
The risk of individual fish being captured multiple times in a catch and release fishery
Thorstad, Eva B.; Diserud, Ola Håvard; Solem, Øyvind; Havn, Torgeir Børresen; Bjørum, Lars Rasmus Oftedal; Kristensen, Torstein; Urke, Henning Andre; Johansen, Martin Rognli; Lennox, Robert J.; Fiske, Peder; Uglem, Ingebrigt (Peer reviewed; Journal article, 2019)The proportion of angled Atlantic salmon Salmo salar L. being caught and released has increased. If individuals are repeatedly captured, this may have fish welfare consequences. Of 995 Atlantic salmon tagged during catch ...
