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 ... -
Population genetic structure of the glacier lanternfish, Benthosema glaciale (Myctophidae) in Norwegian waters
Suneetha, Kristogu Baduge; Salvanes, Anne Gro Vea (Peer reviewed; Journal article, 2001)It is hypothesised that the fjords with restricted water circulation may partially isolate fish populations living there. The pelagic life history stages of the mesopelagic lanternfish may potentially subject to dispersal ... -
Review of ecosystem models of fjords; new insights of relevance to fisheries management
Salvanes, Anne Gro Vea (Peer reviewed; Journal article, 2001)Fjords on the west coast of Norway contain small ecosystems that have similar physical and biological processes as large oceanic ecosystems. Hence, they are ideal experimental facilities. However, ecosystems are complex ... -
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 ... -
Spatial dynamics of the bearded goby and its key fish predators off Namibia vary with climate and oxygen availability
Salvanes, Anne Gro Vea; Bartholomae, Chris H.; Yemane, Dawit; Gibbons, Mark J.; Kainge, Paul; Krakstad, Jens-Otto; Roault, Mathieu; Staby, Arved; Sundby, Svein (Peer reviewed; Journal article, 2015-03)Hypoxia [O2 < 2.0 mL L−1 (87 μmol kg−1)] and severely hypoxic water masses [O2 < 0.5 mL L−1 (21.8 μmol kg−1)] are increasing in coastal marine ecosystems due to eutrophication and warming. Here, we investigate the response ... -
Structure and dynamics of the cod population and trophic interactions in Masfjorden: A contribution to a large-scale cod enhancement experiment
Salvanes, Anne Gro Vea (Doctoral thesis, 1991) -
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 ... -
Sub-populations of coastal cod with different behaviour and life-history strategies
Salvanes, Anne Gro Vea; Skjæraasen, Jon Egil; Nilsen, Trygve (Peer reviewed; Journal article, 2004-02-19)This study provides evidence of countergradient variations in life-history traits among coastal cod Gadus morhua off the Norwegian coast, suggesting the existence of sub-populations. One-yr-old wild-caught individuals from ... -
Temperature-dependent digestion handling time in juvenile cod and possible consequences for prey choice
Knutsen, Ian; Salvanes, Anne Gro Vea (Peer reviewed; Journal article, 1999-05-18)The paper combines experimental work with modelling. The aim was to estimate the temperature-dependent digestion handling time, which is defined as the time taken to digest the whole prey or the whole stomach contents, and ... -
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, ... -
Vertical distribution and trophic interactions of zooplankton and fish in Masfjorden, Norway
Giske, Jarl; Aksnes, Dag Lorents; Balino, Beatriz M.; Kaartvedt, Stein; Lie, Ulf; Nordeide, Jarle Tryti; Salvanes, Anne Gro Vea; Wakili, Sami M.; Aadnesen, Agnes (Peer reviewed; Journal article, 1990)The distribution, biomass, and predator-prey relationships of the pelagic assemblage in Masfjorden, western Norway, was studied in January 1989. The pelagic biomass was dominated by particulate organic matter. Biomasses ... -
Winning ways with hydrogen sulphide on the Namibian shelf
Currie, Bronwen; Utne-Palm, Anne Christine; Salvanes, Anne Gro Vea (Peer reviewed; Journal article, 2018-10-11)The shelf sediments off Namibia are some of the most unusual and extreme marine habitats because of their extremely high hydrogen sulphide concentrations. High surface productivity of the northern Benguela upwelling system ...
