  • “A cleaner break”: Genetic divergence between geographic groups and sympatric phenotypes revealed in ballan wrasse (Labrus bergylta) 
    Seljestad, Gaute; Sanchez, Maria Quintela; Faust, Ellika; Halvorsen, Kim Aleksander Tallaksen; Besnier, Francois; Jansson, Eeva; Dahle, Geir; Knutsen, Halvor; André, Carl; Folkvord, Arild; Glover, Kevin (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Capture and long-distance translocation of cleaner fish to control lice infestations on marine salmonid farms has the potential to influence wild populations via overexploitation in source regions, and introgression in ...
  • Cleaner fish escape salmon farms and hybridize with local wrasse populations 
    Faust, Ellika; Halvorsen, Kim Aleksander Tallaksen; Andersen, Per; Knutsen, Halvor; André, Carl (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    The genetic impact of farmed fish escaping aquaculture is a highly debated issue. However, non-target species, such as cleaner fish used to remove sea lice from farmed fish, are rarely considered. Here, we report that wild ...
  • Harvesting changes mating behaviour in European lobster 
    Sørdalen, Tonje Knutsen; Halvorsen, Kim Aleksander Tallaksen; Harrison, Hugo B.; Ellis, Charlie D.; Vøllestad, Leif Asbjørn; Knutsen, Halvor; Moland, Even; Olsen, Esben Moland (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    Removing individuals from a wild population can affect the availability of prospective mates and the outcome of competitive interactions, with subsequent effects on mating patterns and sexual selection. Consequently, the ...
  • Impact of harvesting cleaner fish for salmonid aquaculture assessed from replicated coastal marine protected areas 
    Halvorsen, Kim Aleksander Tallaksen; Larsen, Torkel; Sørdalen, Tonje Knutsen; Vøllestad, Leif Asbjørn; Knutsen, Halvor; Olsen, Esben Moland (Journal article / Tidsskriftartikkel / SubmittedVersion, 2017)
    Wrasse (Labridae) fisheries have increased markedly in Norway since 2010. Wrasse are being used as cleaner fish in salmonid aquaculture to control sea-lice infestations. However, fundamental knowledge on the demography and ...
  • Marine protected areas rescue a sexually selected trait in European lobster 
    Sørdalen, Tonje Knutsen; Halvorsen, Kim Aleksander Tallaksen; Vøllestad, Leif Asbjørn; Moland, Even; Olsen, Esben Moland (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Marine protected areas (MPAs) are increasingly implemented worldwide to maintain and restore depleted populations. However, despite our knowledge on the myriad of positive responses to protection, there are few empirical ...
  • Movement patterns of temperate wrasses (Labridae) within a small marine protected area 
    Halvorsen, Kim Aleksander Tallaksen; Larsen, Torkel; Browman, Howard; Durif, Caroline; Aasen, Nicolai; Vøllestad, Leif Asbjørn; Cresci, Alessandro; Sørdalen, Tonje Knutsen; Bjelland, Reidun Marie; Skiftesvik, Anne Berit (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    The movement patterns of three commercially important wrasse (Labridae) species inside a small marine protected area (~ 0.15 km2) on the west coast of Norway were analysed over a period of 21 months. The mean distance ...
  • Potential for managing life history diversity in a commercially exploited intermediate predator, the goldsinny wrasse (Ctenolabrus rupestris) 
    Olsen, Esben Moland; Halvorsen, Kim Aleksander Tallaksen; Larsen, Torkel; Kuparinen, Anna (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)
    Small-bodied wrasse species are important for structuring coastal marine ecosystems but are also increasingly harvested as parasite cleaners on farmed salmon. Identifying management regulations that will support long-term ...
  • Selective harvesting and life history variability of corkwing and goldsinny wrasse in Norway: Implications for management and conservation 
    Halvorsen, Kim Aleksander Tallaksen (Doctoral thesis / Doktoravhandling, 2017)
    Selective harvesting, where some individuals are actively targeted or possess phenotypes rendering them more vulnerable to capture, is inevitably happening in all commercial and recreational fisheries. Selective harvesting ...
  • Unlocking the potential of deep learning for marine ecology: overview, applications, and outlook 
    Goodwin, Morten; Halvorsen, Kim Aleksander Tallaksen; Jiao, Lei; Knausgård, Kristian Muri; Martin, Angela Helen; Moyano, Marta; Oomen, Rebekah Alice; Rasmussen, Jeppe Have; Sørdalen, Tonje Knutsen; Thorbjørnsen, Susanna Huneide (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    Abstract The deep learning (DL) revolution is touching all scientific disciplines and corners of our lives as a means of harnessing the power of big data. Marine ecology is no exception. New methods provide ...
