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 ... -
Does vaterite otolith deformation affect post-release survival and predation susceptibility of hatchery-reared juvenile Atlantic Salmon?
Delaval, Aurelien Nicolas; Solås, Martine Røysted; Skoglund, Helge; Salvanes, Anne Gro Vea (Journal article; Peer reviewed, 2021)Sagittal otoliths are calcareous structures in the inner ear of fishes involved in hearing and balance. They are usually composed of aragonite; however, aragonite can be replaced by vaterite, a deformity which is more ... -
Feeding ecology of Benthosema glaciale across the North Atlantic
Knutsen, Tor; Strand, Espen; Klevjer, Thor A.; Salvanes, Anne Gro Vea; Broms, Cecilie; Sunde, Synne Myhre; Aksnes, Dag Lorents; García-Seoane, Eva; Melle, Webjørn Raunsgård (Journal article; Peer reviewed, 2023-02-16)The glacier lanternfish Benthosema glaciale is a key myctophid with a wide distribution in the northern Atlantic. It is a species that has a strong vertical migration capacity and have the potential to move between the ... -
Fishes in a changing world: learning from the past to promote sustainability of fish populations
Gordon, Timothy A.C.; Harding, Harry R.; Clever, Friederike K.; Davidson, Isla Keesje; Davison, William; Montgomery, Daniel W.; Weatherhead, Rebekah C.; Windsor, Fredric M.; Armstrong, John D.; Bardonnet, Agnès; Bergman, Eva; Britton, John Robert; Côté, Isabelle M.; D'agostino, Daniele; Greenberg, Larry; Harborne, Alastair R.; Kahilainen, Kimmo Kalevi; Metcalfe, Neil B.; Mills, Suzanne C.; Milner, Nigel J.; Mittermayer, Felix H.; Montorio, Lucie; Nedelec, Sophie L.; Prokkola, Jenni M.; Rutterford, Louise A.; Salvanes, Anne Gro Vea; Simpson, Stephen D.; Vainikka, Anssi; Pinnegar, John Keith; Santos, Eduarda M. (Journal article; Peer reviewed, 2018)Populations of fishes provide valuable services for billions of people, but face diverse and interacting threats that jeopardize their sustainability. Human population growth and intensifying resource use for food, water, ... -
Genetic structure of Sufflogobius bibarbatus in the Benguela upwelling ecosystem using microsatellite markers
Gunawickrama, Kristogu Baduge Suneetha; Delaval, Aurelien Nicolas; Johansen, Torild; van der Plas, Anja; Salvanes, Anne Gro Vea (Journal article; Peer reviewed, 2020)The bearded goby Sufflogobius bibarbatus is an abundant endemic small fish species on the continental shelf of the northern Benguela. The goby habitat is characterised by generally low bottom oxygen concentrations that ... -
Negative impacts of the sea lice prophylactic emamectin benzoate on the survival of hatchery released salmon smolts in rivers
Lennox, Robert J.; Salvanes, Anne Gro Vea; Barlaup, Bjørn Torgeir; Stöger, Elisabeth; Madhun, Abdullah; Helle, Turid Myklebust; Vollset, Knut (Journal article; Peer reviewed, 2020)Emamectin benzoate (EB) is a prophylactic pharmaceutical used to protect Atlantic salmon (Salmo salar) smolts migrating out of rivers and into the ocean against sea lice parasites. Randomized control trials comparing the ... -
Ontogenetic Change in Behavioral Responses to Structural Enrichment From Fry to Parr in Juvenile Atlantic Salmon (Salmo salar L.)
Alnes, Ingeborg Bjerkvik; Jensen, Knut Helge; Skorping, Arne; Salvanes, Anne Gro Vea (Journal article; Peer reviewed, 2021)Enrichment is widely used as a tool for studying how changes in environment affect animal behavior. Here, we report an experimental study investigating if behaviors shaped by stimuli from environmental enrichment depending ... -
Physical enrichment research for captive fish: Time to focus on the DETAILS
Jones, Nick A. R.; Webster, Mike M.; Salvanes, Anne Gro Vea (Journal article; Peer reviewed, 2021)Growing research effort has shown that physical enrichment (PE) can improve fish welfare and research validity. However, the inclusion of PE does not always result in positive effects and conflicting findings have highlighted ... -
Size-selective harvesting affects the immunocompetence of guppies exposed to the parasite Gyrodactylus
Bartuseviciute, Vitalija; Pauli, Beatriz Diaz; Salvanes, Anne Gro Vea; Heino, Mikko Petteri (Journal article; Peer reviewed, 2022)Harvesting is typically size-selective, targeting large individuals. This is expected to lead to reduced average body size and earlier maturation (i.e. faster life histories). Such changes can also affect traits seemingly ... -
Structure and functioning of four North Atlantic ecosystems - A comparative study
Melle, Webjørn Raunsgård; Klevjer, Thor A.; Drinkwater, Kenneth F.; Strand, Espen; Naustvoll, Lars Johan; Wiebe, Peter H.; Aksnes, Dag Lorents; Knutsen, Tor; Sundby, Svein; Slotte, Aril; Dupont, Nicolas; Salvanes, Anne Gro Vea; Korneliussen, Rolf; Huse, Geir (Journal article; Peer reviewed, 2020)The epi- and mesopelagic ecosystems of four sub-polar ocean basins, the Labrador, Irminger, Iceland and Norwegian seas, were surveyed during two legs from Bergen, Norway, to Nuuk, Greenland, and back to Bergen. The survey ... -
Validating timing of salmon smolt runs obtained by telemetry studies
Hulbak, Magnus Andre; Hanssen, Erlend Mjelde; Lennox, Robert; Salvanes, Anne Gro Vea; Barlaup, Bjørn Torgeir; Gharbi, Naouel; Nilsen, Tom Ole; Vollset, Knut (Journal article; Peer reviewed, 2021)Telemetry tags are increasingly used in management to monitor the migration timing of Atlantic salmon smolts (Salmo salar L.). It has been postulated that (1) effects from tagging and handling may alter migration behaviour, ...
