Safe limits of selenomethionine and selenite supplementation to plant-based Atlantic salmon feeds
(Journal article; Peer reviewed, 2018)The use of plant-based feeds warrants the supplementation with selenium (Se) to cover the requirement for Atlantic salmon. Depending on its chemical form, Se is a trace element with a narrow range between requirement and ... -
Salinity and temperature alter the efficacy of salmon louse prevention
(Peer reviewed; Journal article, 2023)Several promising preventive tools and strategies have been developed to combat infestation of salmon in marine cages by parasitic salmon lice. While most of the prevention strategies tested have significantly reduced louse ... -
Salinity induced changes in the progression of water, ion and nutrient fluxes along the gastrointestinal tract of Atlantic salmon smolt (Salmo salar)
(Peer reviewed; Journal article, 2024)Water ingestion in fish increases with both water salinity and feeding. However, it is unclear whether, during feeding, water ingestion is intended to aid chyme liquefaction in the stomach or to maintain the osmotic ... -
Salmon farming alters the structure and functioning of Norwegian maerl bed communities
(Peer reviewed; Journal article, 2024)Effluents resulting from fish farming activities can alter the structure and functioning of benthic ecosystems. In Norway, recent technological advances within the salmon industry have facilitated the expansion of aquaculture ... -
Salmon in combination with high glycemic index carbohydrates increases diet-induced thermogenesis compared with salmon with low glycemic index carbohydrates?an acute randomized cross-over meal test study
(Journal article; Peer reviewed, 2019)The study investigated the acute effects of meals containing either salmon or veal in combination with carbohydrates with high or low glycemic index (GI) on diet-induced thermogenesis (DIT) (primary endpoint), appetite ... -
Salmon lice (Lepeophtheirus salmonis) development times, body size and reproductive outputs follow universal models of temperature dependence
(Journal article; Peer reviewed, 2016-05-25)Temperatures regulate metabolism of marine ectotherms and thereby influence development, reproduction, and, as a consequence, dispersal. Despite the importance of water temperatures in the epidemiology of marine diseases, ... -
Salmon lice dispersal and population model for management strategy evaluation
(Peer reviewed; Journal article, 2023)Modern marine salmon aquaculture includes management of salmon lice (Lepeophtheirus salmonis) infestations. Moving from a reactive delousing treatment effort to a proactive preventive strategy requires a simulation tool ... -
Salmon lice dispersion in a northern Norwegian fjord system and the impact of vertical movements
(Journal article; Peer reviewed, 2016-02-02)The abundance and distribution of salmon lice Lepeophtheirus salmons originating from fish farms in a northern Norwegian fjord during the summer of 2010 was investigated by means of a numerical model, underpinned by field ... -
Salmon lice evasion, susceptibility, retention, and development differ amongst host salmonid species.
(Peer reviewed; Journal article, 2017)With different ecological characteristics amongst salmonid species, their response to parasitic infestation is likely to vary according to their spatial and temporal overlap with the parasite. This study investigated the ... -
Salmon lice in the Pacific Ocean show evidence of evolved resistance to parasiticide treatment
(Peer reviewed; Journal article, 2022)Parasitic salmon lice (Lepeophtheirus salmonis) threaten the economic and ecological sustainability of salmon farming, and their evolved resistance to treatment with emamectin benzoate (EMB) has been a major problem for ... -
Salmon lice nauplii and copepodids display different vertical migration patterns in response to light
(Peer reviewed; Journal article, 2021)Light is a fundamental environmental cue which influences the migration of many marine organisms. For the salmon louse Lepeophtheirus salmonis, light is believed to drive the diel vertical migration behaviour of their ... -
Salmon lice sampled from wild Atlantic salmon and sea trout throughout Norway display high frequencies of the genotype Associated with pyrethroid resistance
(Journal article; Peer reviewed, 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 ... -
Salmon lice survive the straight shooter: A commercial scale sea cage trial of laser delousing
(Peer reviewed; Journal article, 2020)Ectoparasitic salmon louse (Lepeophtheirus salmonis) infestations are costly for Atlantic salmon (Salmo salar) farmers in Norway. As a result, there is a strong desire for solutions to prevent and control infestations, and ... -
Salmon lice threaten growth, osmoregulation and survival in anadromous Arctic char post-smolts
(Peer reviewed; Journal article, 2019)High salmon lice (Lepeophtheirus salmonis) infestation levels resulting from intensive salmonid sea-cage aquaculture can threaten populations of wild salmonid hosts. This includes anadromous Arctic char (Salvelinus alpinus), ... -
Salmon lice treatments and salmon mortality in Norwegian aquaculture: a review
(Journal article; Peer reviewed, 2018)With the expansion of Atlantic salmon aquaculture, the economic and ecological impacts of salmon lice (Lepeophtheirus salmonis) has increased. Norway battles this problematic parasite with various control and preventative ... -
Salmon lice-induced mortality of Atlantic salmon during post-smolt migration in Norway

The salmon louse genome may be much larger than sequencing suggests.
(Peer reviewed; Journal article, 2022)The genome size of organisms impacts their evolution and biology and is often assumed to be characteristic of a species. Here we present the first published estimates of genome size of the ecologically and economically ... -
The salmon louse genome: Copepod features and parasitic adaptations
(Peer reviewed; Journal article, 2021)Copepods encompass numerous ecological roles including parasites, detrivores and phytoplankton grazers. Nonetheless, copepod genome assemblies remain scarce. Lepeophtheirus salmonis is an economically and ecologically ... -
Salmon louse infestation levels on sea trout can be predicted from a hydrodynamic lice dispersal model
(Peer reviewed; Journal article, 2021)The abundance of the parasitic salmon louse has increased with the growth in aquaculture of salmonids in open net pens. This represents a threat to wild salmonid populations as well as a key limiting factor for salmon ... -
Salmonid alphavirus infection causes skin dysbiosis in Atlantic salmon (Salmo salar L.) post-smolts
