Sequence of formation and inheritance of meristic variation in the post-cranial axial skeleton of Atlantic salmon (Salmo salar)
(Journal article; Peer reviewed, 2025)Atlantic salmon is an important aquaculture species that has fascinated naturalists for centuries, resulting in its biology being widely characterized. Certain details about the early development and the inheritance of ... -
Vertical distribution of mesopelagic organisms under changing oxygen conditions: Insights from western Norwegian fjords
(Doctoral thesis, 2025-04-25)Hver dag migrerer utallige små fisker og virvelløse dyr flere hundre meter mellom overflaten og mesopelagiske dyp (200-1000 m) i takt med døgnsyklusen. Disse mesopelagiske dyrene kan danne tette lag, også kjent som ekkolag, ... -
Sanctuary for vulnerable Arctic species at the Borealis Mud Volcano
(Journal article; Peer reviewed, 2025)Borealis is a recently discovered submerged mud volcano in the Polar North Atlantic, differing from the numerous methane seepages previously identified in the region. Here we show in situ observations from a remotely ... -
Balancing the restoration of a native fish and the risks of hitchhiking invasive species
(Journal article; Peer reviewed, 2025)Reintroducing a species to an area where it is locally extinct may contribute to reestablishing the ecosystem. However, we show that such reintroductions can pose a risk to biodiversity by introducing hitchhiking invasive ... -
Using split beam, broadband acoustics to measure behaviour of salmon in normal and sea lice preventative submerged cages with either air dome or bubbles for swim bladder refilling
(Master thesis, 2023-01-27)Emerging submerged sea cage technologies reduce salmon lice infestations, creating a vertical mismatch between the salmon host and surface-dwelling parasitic larvae. The method challenges swim bladder refilling at the ... -
A pioneering longterm experiment on mesophotic macrofouling communities in the North Atlantic
(Journal article; Peer reviewed, 2024)The mesophotic zone represents one of our planet’s largest and least explored biomes. An increasing number of studies evidence the importance of macrofouling species in marine ecosystems, but information on these communities ... -
Characterization of dead-end knockout Atlantic salmon offspring: mutation frequency, gonad phenotype and exploring the possibilities for using these as surrogates in germ cell transplantations
(Master thesis, 2022-08-29)Reproductively sterile fish in aquaculture has received considerable attention in recent years and is interesting for several reasons. Using sterile Atlantic salmon (Salmo salar) in fish farming could contribute to solving ... -
First Report of ‘Soft Flesh’ Induced by the Parasite Kudoa thyrsites (Myxosporea) in Commercial Codfish From Norway
(Journal article; Peer reviewed, 2024)Kudoa thyrsites is a myxosporean parasite that infects the skeletal muscle of various teleost fish species globally. Severe infections lead to ‘soft flesh’ in fish fillets, resulting in food spoilage and subsequent discard. ... -
Accelerated Sarcopenia Phenotype in the DJ-1/Park7-Knockout Zebrafish
(Journal article; Peer reviewed, 2024)Age-dependent loss of muscle mass and function is associated with oxidative stress. DJ-1/Park7 acts as an antioxidant through multiple signalling pathways. DJ-1-knockout zebrafish show a decline in swimming performance and ... -
Differential regulation of magnesium transporters Slc41, Cnnm and Trpm6-7 in the kidney of salmonids may represent evolutionary adaptations to high salinity environments
(Journal article; Peer reviewed, 2024-11-29)Magnesium is important for enzymatic reactions and physiological functions, and its intracellular concentration is tightly regulated. Atlantic salmon has the ability to handle large changes in environmental Mg2+ concentration ... -
Development and evaluation of generalized fuel models for predicting fire behaviour in northern European heathlands
(Journal article; Peer reviewed, 2024)Northern European heathlands and moorlands dominated by Calluna vulgaris are internationally recognized for their conservation importance while also supporting traditional, low-intensity agriculture and game hunting. Managed ... -
Microclimate, an important part of ecology and biogeography
(Journal article; Peer reviewed, 2024)Brief introduction: What are microclimates and why are they important? Microclimate science has developed into a global discipline. Microclimate science is increasingly used to understand and mitigate climate and biodiversity ... -
Comparing continuous and perfusion cultivation of microalgae on recirculating aquaculture system effluent water
(Journal article; Peer reviewed, 2025)Effluent water from recirculating aquaculture systems (RAS) contains nutrients from fish excrements and leftover feed. This study investigated the nutrient remediation potential from RAS effluent water through microalgae ... -
The dawn of the tropical Atlantic invasion into the Mediterranean Sea
(Journal article; Peer reviewed, 2024)The Mediterranean Sea is a marine biodiversity hotspot already affected by climate- driven biodiversity collapses. Its highly endemic fauna is at further risk if global warming triggers an invasion of tropical Atlantic ... -
Evaluation of stress in farmed Atlantic salmon (Salmo salar) using different biological matrices
(Journal article; Peer reviewed, 2024)Atlantic salmon were subjected to an acute crowding scenario, and their subsequent stress responses were observed under three distinct swimming speed/water flow (WF) conditions: 0.5, 1, and 1.5 body lengths per second ... -
Genetic adaptations for the oceanic success of fish eggs
(Journal article; Peer reviewed, 2024)Genetic adaptations of organisms living in extreme environments are fundamental to our understanding of where life can evolve. Water is the single limiting parameter in this regard, yet when released in the oceans, the ... -
Mesopelagic Fish Traits: Functions and Trade-Offs
(Journal article; Peer reviewed, 2024)Fishes inhabiting the mesopelagic zone of the world's oceans are estimated to account for the majority of the world's fish biomass. They have recently attracted new attention because they are part of the biological carbon ... -
Assessing between-individual variability in bioenergetics modelling: Opportunities, challenges, and potential applications
(Journal article; Peer reviewed, 2024)Population dynamics is influenced by between-individual variability. Dynamic Energy Budget (DEB) theory is an appealing framework for assessing such a variability, yet DEB parameters have rarely been estimated at the ... -
Biomolecular profiles of Arctic sea-ice diatoms highlight the role of under-ice light in cellular energy allocation
(Journal article; Peer reviewed, 2024)Arctic sea-ice diatoms fuel polar marine food webs as they emerge from winter darkness into spring. Through their photosynthetic activity they manufacture the nutrients and energy that underpin secondary production. Sea-ice ... -
Polycladomyces zharkentensis sp. nov., a novel thermophilic cellulose-and starch-degrading member of the Bacillota from a geothermal aquifer in Kazakhstan
(Journal article; Peer reviewed, 2024)A thermophilic, aerobic and heterotrophic filamentous bacterium, designated strain ZKZ2T, was isolated from a pipeline producing hydrothermal water originating from a >2.3 km deep subsurface geothermal source in Zharkent, ...
