Acoustic Delicing of Atlantic Salmon (Salmo salar): Fish Welfare and Salmon Lice (Lepeophtheirus salmonis) Dynamics
(Journal article; Peer reviewed, 2022)Acoustic lice treatment (AcuLice) is a newly developed system, which uses a composite acoustic sound image with low-frequency sound to remove salmon lice (Lepeophtheirus salmonis) from Atlantic salmon (Salmo salar). This ... -
Acoustic telemetry predation sensors reveal the tribulations of Atlantic salmon (Salmo salar) smolts migrating through lakes
(Journal article; Peer reviewed, 2021)Smolt migration through lakes is hazardous, as the predation pressure can be extreme and the hydrology a great contrast to that of a riverine area. However, the mechanisms yielding these challenges have been scarcely ... -
Actin N-terminal acetylation impacts cell adhesion and invasion
(Master thesis, 2019-12-14) -
Actions on sustainable food production and consumption for the post-2020 global biodiversity framework
(Journal article; Peer reviewed, 2021)Current food production and consumption trends are inconsistent with the Convention on Biological Diversity’s 2050 vision of living in harmony with nature. Here, we examine how, and under what conditions, the post-2020 ... -
Activation mechanism and activity of globupain, a thermostable C11 protease from the Arctic Mid-Ocean Ridge hydrothermal system
(Journal article; Peer reviewed, 2023)Deep-sea hydrothermal vents offer unique habitats for heat tolerant enzymes with potential new enzymatic properties. Here, we present the novel C11 protease globupain, which was prospected from a metagenome-assembled genome ... -
Acute effects of gas supersaturation on Atlantic salmon smolt in two Norwegian rivers
(Journal article; Peer reviewed, 2020)Total dissolved gas (TDG) supersaturation downstream of hydropower plants may cause gas bubble disease (GBD) and harmful effects in fish. Little is known about tolerance levels of TDG supersaturation on Atlantic salmon ... -
Adaptation of anemonefish to their host anemones: From Genetics to Physiology
(Doctoral thesis, 2020-02-21)The mutualism between anemonefish and anemones can be studied in terms of permanent or temporary adaptation of fish toward their host anemones. This thesis explores this theme, and aims to test (1) Whether a mutual ... -
Adaptation of unbiased stereological methods to study theeffects of feed composition on the morphometrics of the different layers of the digestive tract of juvenile Atlantic cod (Gadus morhua L.)
(Master thesis, 2004)Juveniles of Atlantic cod (Gadus morhua L.) were fed food, containing different compositions of macro-nutrients (proteins, fat and carbohydrates). The aims of this study were to evaluate the use of unbiased stereology to ... -
Adaptive and plastic variation in growth and maturation of the cutlassfish Trichiurus japonicus in the subtropical Pacific Ocean
(Peer reviewed; Journal article, 2018) -
Adaptive evolution of viruses infecting marine microalgae (haptophytes), from acute infections to stable coexistence
(Journal article; Peer reviewed, 2022)Collectively known as phytoplankton, photosynthetic microbes form the base of the marine food web, and account for up to half of the primary production on Earth. Haptophytes are key components of this phytoplankton community, ... -
Adaptive host responses to infection can resemble parasitic manipulation
(Journal article; Peer reviewed, 2023)Using a dynamic optimisation model for juvenile fish in stochastic food environments, we investigate optimal hormonal regulation, energy allocation and foraging behaviour of a growing host infected by a parasite that only ... -
Adaptive Humoral Immune Response in Lumpfish, Cyclopterus lumpus L.
(Master thesis, 2015-10-05)The lumpfish, Cyclopterus lumpus L. is an emerging and most promising aquaculture fish currently used for a biological control against sea lice in salmonids. However, the lumpfish is prone to a number of bacterial diseases ... -
Adaptive immune responses in Atlantic salmon after vaccination with bacterins of Pasteurella atlantica
(Master thesis, 2022-06-01)Utbrot av pasteurellose hjå atlanterhavslaks (Salmo salar L.) har sidan 2018 vore eit stort problem i oppdrettsnæringa, og framleis har inga kommersielt tilgjengeleg vaksine blitt utvikla. Vi veit lite om bakteriens ... -
Adding pieces to the puzzle: insights into diversity and distribution patterns of Cumacea (Crustacea: Peracarida) from the deep North Atlantic to the Arctic Ocean
(Journal article; Peer reviewed, 2021)The Nordic Seas have one of the highest water-mass diversities in the world, yet large knowledge gaps exist in biodiversity structure and biogeographical distribution patterns of the deep macrobenthic fauna. This study ... -
Adipose tissue fatty acids suggest spatial and temporal dietary differences in great cormorants of the Baltic Sea area
(Journal article; Peer reviewed, 2021)Increased numbers of great cormorants (Phalacrocorax carbo) in the Baltic Sea may have local impacts on fisheries and salmonid hatcheries. We studied spatial and temporal variability in cormorant diet, and potential ... -
Adult body growth and reproductive investment vary markedly within and across Atlantic and Pacific herring: a meta-analysis and review of 26 stocks
(Journal article; Peer reviewed, 2021)Life-history traits of Pacific (Clupea pallasii) and Atlantic (Clupea harengus) herring, comprising both local and oceanic stocks subdivided into summer-autumn and spring spawners, were extensively reviewed. The main ... -
Advances in herring biology: from simple to complex, coping with plasticity and adaptability
(Peer reviewed; Journal article, 2009)At least two centuries of investigations on herring have been absorbed by scientific journals, and applied and fundamental research has produced groundbreaking concepts in fisheries, population biology, and marine ecology. ... -
Age and growth determination and stock identification using statolith microstructure of Indian squid, Loligo duvauceli
(Master thesis, 2010-05-29)Age and growth and stock identification of Indian squid, Loligo duvauceli were examined by statolith microstructure and morphological measurements. The Indian squid were sampled from the Gulf of Thailand and the Andaman ... -
Age determination of Atlantic halibut (Hippoglossus hippoglossus L.) - Size at age and regional growth differences along the coast of Norway
(Master thesis, 2011-05-25)The traditional method for estimating age of Atlantic halibut (Hippoglossus hippoglossus) is through surface readings. Previous studies have not been compared to find the best practice for surface reading techniques. Based ... -
Aggregations of foraging black guillemots (Cepphus grylle) at a sea-ice edge in front of a tidewater glacier
(Journal article; Peer reviewed, 2022)Seabirds in cold biomes sometimes aggregate near glacier fronts and at sea-ice edges to forage. In this note, we report on large aggregations of black guillemots (Cepphus grylle) at the edge of sea ice in front of the ...
