Behavioural and physiological adaptations of the bearded goby, a key fish species of the extreme environment of the northern Benguela upwelling
Salvanes, Anne Gro Vea; Utne-Palm, Anne Christine; Currie, Bronwen; Braithwaite, Victoria A. (Peer reviewed; Journal article, 2011-03-14)Nutrient-rich, upwelling marine areas with high productivity often produce sediments dominated by organic-rich mud. Here, intense decay processes create hypoxic conditions with high concentrations of hydrogen sulphide and ... -
Enrichment promotes learning in fish
Strand, David A.; Utne-Palm, Anne Christine; Jakobsen, Per Johan; Braithwaite, Victoria A.; Jensen, Knut Helge; Salvanes, Anne Gro Vea (Peer reviewed; Journal article, 2010-08-18)Captive birds and mammals reared in enriched rearing environments have been shown to behave more flexibly compared to animals reared in impoverished or plain environments. Recent evidence has shown that this is also true ... -
Improving size selection in the Norwegian red king crab (Paralithodes camtschaticus) fishery through modification to pot design and soak time
Anders, Neil; Arnesen, Kenneth; Hustad, Anette; Jørgensen, Terje; Løkkeborg, Svein; Siikavuopio, Sten Ivar; Thesslund, Tina; Utne-Palm, Anne Christine (Journal article; Peer reviewed, 2023)Red king crab (Paralithodes camtschaticus) represent a valuable inshore fisheries resource for communities in northern Norway. The fishery is regulated east of the 26th meridian by vessel quotas and a minimum landing size ... -
Opposite selection on behavioural types by active and passive fishing gears in a simulated guppy Poecilia reticulata fishery
Diaz Pauli, Beatriz; Wiech, Martin; Heino, Mikko Petteri; Utne-Palm, Anne Christine (Peer reviewed; Journal article, 2015-03)This study assessed whether fishing gear was selective on behavioural traits, such as boldness and activity, and how this was related with a productivity trait, growth. Female guppies Poecilia reticulata were screened for ... -
Size Dependent Male Reproductive Tactic in the Two-Spotted Goby (Gobiusculus flavescens)
Utne-Palm, Anne Christine; Eduard, Kjartan; Jensen, Knut Helge; Mayer, Ian; Jakobsen, Per Johan (Peer reviewed; Journal article, 2015-12-07)Male investment in testes and sperm duct gland in the polygamous nest breeding two-spotted goby Gobiusculus flavescens (Fabricius) was investigated in relation to time in reproductive season and individual physical parameters. ... -
Towards more efficient longline fisheries: fish feeding behaviour, bait characteristics and development of alternative baits
Løkkeborg, Svein; Siikavuopio, Sten Ivar; Humborstad, Odd Børre; Utne-Palm, Anne Christine; Ferter, Keno (Peer reviewed; Journal article, 2014-12)Better knowledge of food search behavior in fish is essential for studies that aim to improve longline fishing, particularly through bait development. This review provides an overview of our understanding of how fish detect ... -
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 ...
