Acoustic telemetry predation sensors reveal the tribulations of Atlantic salmon (Salmo salar) smolts migrating through lakes
Hanssen, Erlend Mjelde; Vollset, Knut Wiik; Salvanes, Anne Gro Vea; Barlaup, Bjørn; Whoriskey, Kim; Isaksen, Trond Einar; Normann, Eirik Straume; Hulbak, Magnus Andre; Lennox, Robert (Journal article; Peer reviewed, 2021)Smolt migration through lakes is hazardous, as the predation pressure can be extreme and the hydrology a great contrast to that of a riverine area. However, the mechanisms yielding these challenges have been scarcely ... -
Behavioural response of brown trout (Salmo trutta) to total dissolved gas supersaturation in a regulated river
Lennox, Robert J.; Thiemer, Kirstine; Vollset, Knut Wiik; Pulg, Ulrich; Stranzl, Sebastian; Nilsen, Cecilie Iden; Haugen, Thrond Oddvar; Velle, Gaute (Journal article; Peer reviewed, 2022)Total dissolved gas supersaturation from dams and power stations is a chronic freshwater pollutant that is toxic to animals with aquatic respiration. Laboratory ecotoxicology experiments have revealed capacity for captive ... -
Differences in growth and survival between cod Gadus morhua and herring Clupea harengus early stages co-reared at variable prey concentrations
Folkvord, Arild; Vollset, Knut Wiik; Catalan, Ignacio (Peer reviewed; Journal article, 2015-09-28)It was hypothesized that the survival and growth strategies of herring Clupea harengus, displaying a flexible reproductive activity, are adapted to coping with longer periods of prey deprivation (i.e. more variable prey ... -
Foraging behaviour of larval cod (Gadus morhua) at low light intensities
Vollset, Knut Wiik; Folkvord, Arild; Browman, H. I. (Peer reviewed; Journal article, 2011-02-13)The ability to forage at lowlight intensities can be of great importance for the survival of fish larvae in a pelagic environment. Three-dimensional silhouette imaging was used to observe larval cod foraging and swimming ... -
Negative association of sea lice from fish farms on recreational fishing catches of Atlantic salmon
Larsen, Mari Lie; Vormedal, Irja H; Vollset, Knut Wiik (Journal article; Peer reviewed, 2024)The question of whether and to what extent sea-louse (Lepeophtheirus salmonis) infestations from salmon farms influence wild Atlantic salmon survival has been subject to sustained scientific debate and political controversy. ...
