Statistical and ecological challengesof monitoring parasitic salmon lice infestationsin wild salmonid fish stocks
Helland, Ingeborg Palm; Uglem, Ingebrigt; Jansen, Peder A; Diserud, Ola Håvard; Bjørn, Pål Arne; Finstad, Bengt (Journal article; Peer reviewed, 2015-12-03)Ecological monitoring programmes should provide precise data to inform management, but the data quality is often limited by methodological challenges and the need for cost-effective sampling. Parasite infestations are ... -

Timing is everything: Survival of Atlantic salmon Salmo salar postsmolts during events of high salmon lice densities
Bøhn, Thomas; Gjelland, Karl Øystein; Serra Llinares, Rosa Maria; Finstad, Bengt; Primicerio, Raul; Nilsen, Rune; Karlsen, Ørjan; Sandvik, Anne Dagrun; Skilbrei, Ove Tommy; Elvik, Kristine Marit Schrøder; Skaala, Øystein; Bjørn, Pål Arne (Peer reviewed; Journal article, 2020)Atlantic salmon in aquaculture act as reservoir hosts and vectors of parasites like salmon lice and this parasite is shown to harm wild salmonid populations. In this study, n = 29,817 tagged Atlantic salmon were studied ... -
Toward a model-based prediction system for salmon lice infestation pressure
Sandvik, Anne Dagrun; Bjørn, Pål Arne; Ådlandsvik, Bjørn; Asplin, Lars; Skardhamar, Jofrid; Johnsen, Ingrid Askeland; Myksvoll, Mari Skuggedal; Skogen, Morten D. (Journal article; Peer reviewed, 2016-09-08)High salmon lice density is a threat to wild and farmed salmonid fish in Norway. To assess and identify areas for high salmon lice infestation pressure, continuous monitoring is necessary. The national Norwegian salmon ... -
Towards direct evidence of the effects of salmon lice (Lepeophtheirus salmonis Kr?yer) on sea trout (Salmo trutta L.) in their natural habitat: proof of concept for a new combination of methods
Serra Llinares, Rosa Maria; Freitas, Carla; Nilsen, Rune; Elvik, Kristine Marit Schrøder; Albretsen, Jon; Bøhn, Thomas; Karlsen, Ørjan; Bjørn, Pål Arne (Journal article; Peer reviewed, 2018)Studies addressing the impact of salmon lice (Lepeophtheirus salmonis Krøyer) on sea trout in their natural habitat are scarce and mostly limited to prophylaxis-based experiments. The main drawbacks with this approach are ... -
Variations in coastal fish species composition captured by traps in Romsdalsfjord, Western Norway
Arechavala-Lopez, Pablo; Berg, Marius; Uglem, Ingebrigt; Bjørn, Pål Arne; Finstad, Bengt (Journal article; Peer reviewed, 2016-03-03)Fish traps are widely used in Norwegian fjords, especially those designed for monitoring salmonid populations in the marine environment, although many other marine fish species are also captured. The composition and ...
