RNA sequencing and proteomic profiling reveal different alterations by dietary methylmercury in the hippocampal transcriptome and proteome in BALB/c mice
(Peer reviewed; Journal article, 2021)Methylmercury (MeHg) is a highly neurotoxic form of mercury (Hg) present in seafood. Here, we recorded and compared proteomic and transcriptomic changes in hippocampus of male BALB/c mice exposed to two doses of MeHg. Mice ... -
RNAIDNA ratios and growth of herring larvae

The role of chloroplast movement in C4 photosynthesis: A theoretical analysis using a three-dimensional reaction-diffusion model for maize
(Peer reviewed; Journal article, 2023)Chloroplasts movement within mesophyll cells in C4 plants is hypothesized to enhance the CO2 concentrating mechanism, but this is difficult to verify experimentally. A three-dimensional (3D) leaf model can help analyse how ... -
The role of marine mammals in the Barents Sea foodweb
(Peer reviewed; Journal article, 2019)Marine mammals are important players in the Barents Sea ecosystem but their structural role in the foodweb has been little explored. We compare foodweb-related characteristics within and between phylogenetic groups for 19 ... -
Role of the Melanocortin System in Gonadal Steroidogenesis of Zebrafish
(Peer reviewed; Journal article, 2022)In teleost, as in other vertebrates, stress affects reproduction. A key component of the stress response is the pituitary secretion of the adrenocorticotropic hormone (ACTH), which binds to the melanocortin 2 receptor ... -
Roles of three putative salmon louse (Lepeophtheirus salmonis) prostaglandin E2synthases in physiology and host–parasite interactions
(Peer reviewed; Journal article, 2021)The salmon louse (Lepeophtheirus salmonis) is a parasite of salmonid fish. Atlantic salmon (Salmo salar) exhibit only a limited and ineffective immune response when infested with this parasite. Prostaglandins (PGs) have ... -
Round-trip migration and energy budget of a breeding female humpback whale in the Northeast Atlantic
(Others, 2022)In the northern hemisphere, humpback whales (Megaptera novaeangliae) typically migrate between summer/autumn feeding grounds at high latitudes, and specific winter/spring breeding grounds at low latitudes. Northeast Atlantic ... -

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 ... -
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 infection on wild salmonids in marine protected areas: an evaluation of the Norwegian ‘National Salmon Fjords
(Journal article; Peer reviewed, 2014-02-05)In Norway, 29 fjords and 52 rivers have been designated for protection in order to prevent the infection of important populations of wild salmonids with salmon lice of farm origin. We evaluated the effect of this protection ... -
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 ...
