Optimization of high-throughput lipid screening of the microalga Nannochloropsis oceanica using BODIPY 505/515
(Journal article; Peer reviewed, 2021-03)Background Microalgae are considered a promising platform for sustainable lipid production. Despite this, productivities need to be improved to facilitate an economically viable production process. This can be achieved ... -
Transcriptomic comparison of communally reared wild, domesticated and hybrid Atlantic salmon fry under stress and control conditions
(Journal article; Peer reviewed, 2020)Background Domestication is the process by which organisms become adapted to the human-controlled environment. Since the selection pressures that act upon cultured and natural populations differ, adaptations that favour ... -
Atlantic salmon Salmo salar and ballan wrasse Labrus bergylta display different susceptibility to clonal strains of Paramoeba perurans
(Journal article; Peer reviewed, 2020)Amoebic gill disease (AGD), caused by the marine amoeba Paramoeba perurans, is an important disease of farmed Atlantic salmon Salmo salar L. in Norway. The use of wrasse as cleaner fish in salmon net pens raises questions ... -
No environmental effect on vaccine-induced reduced growth in Atlantic salmon Salmo salar smolts
(Journal article; Peer reviewed, 2020)Oil-adjuvanted vaccines reduce long-term growth in farmed Atlantic salmon Salmo salar, possibly via an increase in metabolic rate due to the energetic demands of the immune system. We tested this hypothesis by comparing ... -
The Melting Snowball Effect: A Heuristic for Sustainable Arctic Governance Under Climate Change
(Journal article; Peer reviewed, 2020)Climate change in the Arctic is occurring at a rapid rate. In Longyearbyen, Svalbard, the world’s northernmost city, deadly avalanches and permafrost thaw-induced architectural destruction has disrupted local governance ... -
Catch me if you can: How to recapture lumpfish using light as an attractant
(Journal article; Peer reviewed, 2020)The use of lumpfish in salmon farming allows the removal of sea lice all year round, without the use of chemicals or mechanical treatments. In Norway alone, around 31 million lumpfish are currently put into sea pens whereas ... -
Rainbow trout Oncorhynchus mykiss skin responses to salmon louse Lepeophtheirus salmonis: From copepodid to adult stage
(Journal article; Peer reviewed, 2020)The marine crustacean Lepeophtheirus salmonis (salmon louse) is a common ectoparasite of wild and farmed salmonids. The parasite has a complex ontogeny comprising eight instars. The planktonic copepodid stage settles on ... -
Distribution and suitable habitat of the cold-water corals Lophelia pertusa, Paragorgia arborea, and Primnoa resedaeformis on the Norwegian continental shelf
(Journal article; Peer reviewed, 2020)Cold-water corals are habitat-forming species that are also classified as indicators of vulnerable marine ecosystems (VMEs) due to the threat of various anthropogenic impacts, e.g., fisheries and oil/mineral exploration. ... -
Atlantic salmon and sea trout display synchronised smolt migration relative to linked environmental cues
(Journal article; Peer reviewed, 2020)Anadromous salmon and sea trout smolts face challenging migrations from freshwater to the marine environment characterised by high mortality. Therefore, the timing of smolt migration is likely to be critical for survival. ... -
Making the best of lousy circumstances: The impact of salmon louse Lepeophtheirus salmonis on depth preference of sea trout Salmo trutta
(Journal article; Peer reviewed, 2020)ABSTRACT: Sea trout are known for seeking out sources of freshwater to rid themselves of salmon lice. However, the effect of natural haloclines in fjords on parasite dynamics is not well understood. We tagged 48 naturally ... -
A Neural Network-Based Analysis of the Seasonal Variability of Surface Total Alkalinity on the East China Sea Shelf
(Journal article; Peer reviewed, 2020)Total alkalinity (AT) is an important variable in the regulation of the seawater carbonate chemistry system, determining the capacity to buffer changes in pH. In the coastal oceans, carbonate system dynamics are controlled ... -
Parasite development affect dispersal dynamics; infectivity, activity and energetic status in cohorts of salmon louse copepodids
(Journal article; Peer reviewed, 2020)The salmon louse, Lepeophtheirus salmonis, is a parasitic copepod infecting wild and farmed salmonid fishes in the northern hemisphere. It has a direct lifecycle with a planktonic dispersal phase and an infective copepodid ... -
Genetic structure of Sufflogobius bibarbatus in the Benguela upwelling ecosystem using microsatellite markers
(Journal article; Peer reviewed, 2020)The bearded goby Sufflogobius bibarbatus is an abundant endemic small fish species on the continental shelf of the northern Benguela. The goby habitat is characterised by generally low bottom oxygen concentrations that ... -
Cleaner fish growth, welfare and survival in Atlantic salmon sea cages during an autumn-winter production
(Journal article; Peer reviewed, 2020)Cleaner fish used as a biological control agent against salmon lice is rapidly increasing in Atlantic salmon aquaculture. However, concerns have been raised about the welfare and mortality of cleaner fish in salmon cage ... -
Using Red List species in designating protection status to forest areas: a case study on the problem of spatio-temporal dynamics
(Journal article; Peer reviewed, 2020)Red-listed species are often used as target species in selection of sites for conservation. However, limitations to their use have been pointed out, and here we address the problem of expected high spatio-temporal dynamics ... -
Fe(II) stability in coastal seawater during experiments in Patagonia, Svalbard, and Gran Canaria
(Journal article; Peer reviewed, 2020-03)The speciation of dissolved iron (DFe) in the ocean is widely assumed to consist almost exclusively of Fe(III)-ligand complexes. Yet in most aqueous environments a poorly defined fraction of DFe also exists as Fe(II), the ... -
Deep-sea sponge grounds as nutrient sinks: Denitrification is common in boreo-Arctic sponges
(Journal article; Peer reviewed, 2020-03)Sponges are commonly known as general nutrient providers for the marine ecosystem, recycling organic matter into various forms of bioavailable nutrients such as ammonium and nitrate. In this study we challenge this view. ... -
A case study of biofilter activation and microbial nitrification in a marine recirculation aquaculture system for rearing Atlantic salmon (Salmo salar L.)
(Peer reviewed; Journal article, 2020-09)Marine recirculation aquaculture system (RAS) is a prominent technology within fish farming. However, the nitrifying bacteria in the biofilter have low growth rates, which can make the biofilter activation a long and ... -
Taxonomy of the order Mononegavirales: update 2019
(Journal article; Peer reviewed, 2019)In February 2019, following the annual taxon ratification vote, the order Mononegavirales was amended by the addition of four new subfamilies and 12 new genera and the creation of 28 novel species. This article presents ... -
Modelling sea lice control by lumpfish on Atlantic salmon farms: Interactions with mate limitation, temperature and treatment rules
(Journal article; Peer reviewed, 2019)Atlantic salmon farming is one of the largest aquaculture sectors in the world. A major impact on farm economics, fish welfare and, potentially, nearby wild salmonid populations, is the sea louse ectoparasite Lepeophtheirus ...
