Behavior-dependent selectivity of yellowtail flounder (Limanda ferruginea) in the mouth of a commercial bottom trawl
Underwood, Melanie; Winger, Paul D.; Fernø, Anders; Engås, Arill (Peer reviewed; Journal article, 2015-09-02)To improve the efficiency of a commercial bottom trawl for catching yellowtail flounder (Limanda ferruginea), we studied the behavior of individuals in the middle of the trawl mouth. Observations were conducted with a ... -
The dynamics of a metapopulation: Changes in life-history traits in resident herring that co-occur with oceanic herring during spawning
Johannessen, Arne; Skaret, Georg; Langård, Lise; Slotte, Aril; Husebø, Åse; Fernø, Anders (Peer reviewed; Journal article, 2014-07-22)Different populations of Atlantic herring are regarded as forming a metapopulation, but we know little about the dynamics of the connectivity and degree of interbreeding between the populations. Based on data from three ... -
Efficiency and catch dynamics of collapsible square and conical crab pots used in the red king crab (Paralithodes camtschaticus) fishery
Stiansen, Stian; Fernø, Anders; Furevik, Dag; Jørgensen, Terje; Løkkeborg, Svein (Peer reviewed; Journal article, 2008)We compared the capture efficiency and catch dynamics of collapsible square and conical pots used in resource assessment and harvesting of red king crabs (Paralithodes camtschaticus [Tilesius, 1815]) in the Barents Sea. ... -
An enriched environment promotes shelter-seeking behaviour and survival of hatchery-produced juvenile European lobster (Homarus gammarus)
Aspaas, Stian; Grefsrud, Ellen Sofie; Fernø, Anders; Jensen, Knut Helge; Trengereid, Henrik; Agnalt, Ann-Lisbeth (Peer reviewed; Journal article, 2016-08-25)The high loss of newly released hatchery-reared European lobster (Homarus gammarus) juveniles for stock enhancement is believed to be the result of maladaptive anti-predator behaviour connected to deprived stimuli in the ... -
Fast water currents reduce production performance of post-smolt Atlantic salmon Salmo salar
Solstorm, Frida; Solstorm, David; Oppedal, Frode; Fernø, Anders; Fraser, Thomas; Olsen, Rolf Erik (Peer reviewed; Journal article, 2015-09-17)In the future, an increasing number of salmon farms may be located in areas with fast water current velocity due to limited availability of more sheltered locations. However, there is little information as to how fast ... -
The interaction between water currents and salmon swimming behaviour in sea cages
Johansson, David; Laursen, Frida Maria; Fernø, Anders; Fosseidengen, Jan Erik; Pascal, Klebert; Stien, Lars Helge; Vågseth, Tone; Oppedal, Frode (Peer reviewed; Journal article, 2014-05-15)Positioning of sea cages at sites with high water current velocities expose the fish to a largely unknown environmental challenge. In this study we observed the swimming behaviour of Atlantic salmon (Salmo salar L.) at a ... -
State-dependent spatial and intra-school dynamics in pre-spawning herring (Clupea harengus L.) in a semi-enclosed ecosystem
Langård, Lise; Fatnes, Ole Andreas; Johannessen, Arne; Skaret, Georg; Axelsen, Bjørn Erik; Nøttestad, Leif; Slotte, Aril; Jensen, Knut Helge; Fernø, Anders (Peer reviewed; Journal article, 2013)Distribution and aggregation patterns of pelagic fish in marine ecosystems are hard to predict and understand, particularly since focused studies are typically limited to single field efforts. Our study targets coastal ...
