Migration of Atlantic salmon post-smolts in a fjord with high infestation pressure of salmon lice
Halttunen, Elina; Gjelland, Karl Øystein; Glover, Kevin; Johnsen, Ingrid Askeland; Serra-Llinares, Rosa-Maria; Skaala, Øystein; Nilsen, Rune; Bjørn, Pål Arne; Karlsen, Ørjan; Finstad, Bengt; Skilbrei, Ove Tommy (Peer reviewed; Journal article, 2018)Understanding Atlantic salmon Salmo salar post-smolt coastal migration behaviour is crucial for predicting their exposure to ecological challenges such as the parasite salmon louse Lepeophtheirus salmonis. We compared the ... -
The Phe362Tyr mutation conveying resistance to organophosphates occurs in high frequencies in salmon lice collected from wild salmon and trout
Fjørtoft, Helene Børretzen; Besnier, Francois; Stene, Anne; Nilsen, Frank; Bjørn, Pål Arne; Tveten, Ann-Kristin; Finstad, Bengt; Aspehaug, Vidar; Glover, Kevin (Peer reviewed; Journal article, 2017-10-27)The parasitic salmon louse, and its resistance to chemical delousing agents, represents one of the largest challenges to the salmon aquaculture industry. We genotyped lice sampled from wild salmon and sea trout throughout ... -
Salmon lice sampled from wild Atlantic salmon and sea trout throughout Norway display high frequencies of the genotype Associated with pyrethroid resistance
Fjørtoft, Helene Børretzen; Nilsen, Frank; Besnier, Francois; Stene, Anne; Bjørn, Pål Arne; Tveten, Ann-Kristin; Aspehaug, Vidar Teis; Finstad, Bengt; Glover, Kevin (Peer reviewed; Journal article, 2019)Atlantic salmon Salmo salar aquaculture is based on the use of open-pen sea cages, with the consequence that farmed fish are both recipients and sources of pathogens from surrounding waters. Currently, the parasitic salmon ... -
Vurdering av lakselusindusert villfiskdødelighet per produksjonsområde i 2016 og 2017
Nilsen, Frank; Ellingsen, Ingrid; Finstad, Bengt; Jansen, Peder A.; Karlsen, Ørjan; Kristoffersen, Anja B.; Sandvik, Anne D.; Sægrov, Harald; Ugedal, Ola; Vollset, Knut W.; Myksvoll, Mari Skuggedal (Research report, 2017)Ekspertgruppen ble i mars 2017 oppnevnt for ett år for å foreta en vurdering av lakselusindusert dødelighet på villfisk i 13 produksjonsområder i Norge. En foreløpig rapport basert på data fra 2016 ble levert i april 2017 ...
