Bioglider: an integrated glider solution for enhancing environmental knowledge
(Peer reviewed; Journal article, 2023)This paper presents a technological solution for the observation and monitoring of the marine ecosystem. Three complementary devices, one optic imaging and one scientific acoustic instrument as well as one acoustic ... -
Quantifying zoobenthic blue carbon storage across habitats within the Arctic’s Barents Sea
(Peer reviewed; Journal article, 2023)The Arctic sea ice extent in September (when it is at its lowest) has declined 13% Q10 per decade, and the Arctic Ocean is becoming a more Atlantic-influenced system. Rapid climate-forced changes are taking place in many ... -
Effects of capture-related stress and pre-freezing holding in refrigerated sea water (RSW) on the muscle quality and storage stability of Atlantic mackerel (Scomber scombrus) during subsequent frozen storage
(Peer reviewed; Journal article, 2024)Crowded (stressed) and unstressed Atlantic mackerel with or without pre-freezing holding in refrigerated sea water (RSW) were stored at −19 °C for ∼12 months and analysed for nucleotide degradation (K value), muscle pH, ... -
Discovery of polycyclic aromatic acid metabolites in fish exposed to the petroleum compounds 1-methylphenanthrene and 1,4-dimethylphenanthrene
(Peer reviewed; Journal article, 2024)Most of the polycyclic aromatic hydrocarbons (PAHs) in petroleum are alkylated (alkyl PAHs), still the metabolism of these alkyl PAHs to the expected acid products (polycyclic aromatic acids; PAAs) has yet to be demonstrated ... -
Complete sequence of a new conjugative multidrug-resistance encoding IncFII/IncFIA/IncFIB plasmid carrying NDM-6 metallo-β-lactamase from pathogenic Escherichia coli sequence type 167 isolated from sewage in Norway
(Peer reviewed; Journal article, 2023)The aim of the current study was to determine the genomic map of resistance genes and to understand the potential for mobility of a new NDM-6-carrying plasmid from a pathogenic Escherichia coli strain. A complete and closed ... -
Tissue accumulation of polystyrene microplastics causes oxidative stress, hepatopancreatic injury and metabolome alterations in Litopenaeus vannamei
(Peer reviewed; Journal article, 2023)Microplastics (MPs) pose one of the major environmental threats to marine organisms and ecosystems on a global scale. Although many marine crustaceans are highly susceptible to MPs pollution, the toxicological effects and ... -
The effects of spatial and temporal variations in spawning on offspring survival in Northeast Arctic cod
(Peer reviewed; Journal article, 2023)Climate change and harvesting result in temporal and spatial changes and variability in spawning, and thus in offspring ambient drift conditions. As a result, variable survival of offspring and thereby in recruitment are ... -
A first ecological coherent assessment of eutrophication across the North-East Atlantic waters (2015-2020)
(Peer reviewed; Journal article, 2023) -
Applications and analytical approaches using imaging sonar for quantifying behavioural interactions among aquatic organisms and their environment
(Peer reviewed; Journal article, 2023)For many aquatic animals, distributional patterns, trophodynamic relationships, and reproductive activity are driven by complex biotic and abiotic ecosystem interactions that influence behaviour. Linking behavioural ... -
Evaluation of black soldier fly larvae meal as a functional feed ingredient in Atlantic salmon (Salmo salar) under farm-like conditions
(Peer reviewed; Journal article, 2023)Atlantic salmon (Salmo salar) were fed diets containing black soldier fly larvae (BSFL) meal at two inclusion levels for 13 months in open sea-cages. BSFL meal replaced plant-based ingredients and dietary insect meal ... -
Exploring fishing impacts on the structure and functioning of the Yellow Sea ecosystem using an individual-based modeling approach
(Peer reviewed; Journal article, 2023)The Yellow Sea is a marginal sea in the Northwestern Pacific where the fishery resources have been overfished and the community structure has greatly changed over the past six decades. Ecosystem modeling approaches are ... -
Spawning manipulation, broodfish diet feeding and egg production in farmed Atlantic salmon
(Peer reviewed; Journal article, 2024)Atlantic salmon aquaculture relies on continuous supply of high quality eggs. Broodfish nutrition and manipulation of ovulation time (photoperiod and temperature) are key factors. The optimum feeding period with broodfish ... -
Poleward spawning of Atlantic mackerel (Scomber scombrus) is facilitated by ocean warming but triggered by energetic constraints
(Peer reviewed; Journal article, 2023)The Northeast Atlantic mackerel is an income breeder with indeterminate fecundity, spawning in multiple batches at optimal temperatures around 11°C in the upper water column during February–July along the continental shelf ... -
Recruitment regime shifts and nonstationarity are widespread phenomena in harvestable stocks experiencing pronounced climate fluctuations
(Peer reviewed; Journal article, 2023)Methods to reliably identify jump discontinuities in biological time series and to assess the specific contribution of various covariates are rapidly progressing. Here, we took advantage of these statistical improvements ... -
Large annual variation in the amount of skipped spawning for female Northeast Arctic haddock Melanogrammus aeglefinus
(Peer reviewed; Journal article, 2020)Although the phenomenon of skipped spawning has been described in numerous fishes, time-series are scarce. We used the presence of post-ovulatory follicles in histological gonad slides from females not developing oocytes ... -
Defining sustainable and precautionary harvest rates for data-limited short-lived stocks: a case study of sprat (Sprattus sprattus) in the English Channel
(Peer reviewed; Journal article, 2023)Empirical harvest control rules set catch advice based on observed indicators and are increasingly being used worldwide to manage fish stocks that lack formal assessments of stock and exploitation status. Within the ... -
Size-selective harvesting alters biological traits of marine medaka (Oryzias melastigma)
(Peer reviewed; Journal article, 2023)Under long-term fishing pressure, the biological traits of many wild fish populations have changed. Such phenotypic changes include smaller in size and earlier age-at-maturation, strongly suggesting that fishing could ... -
Occurrence of salmonid alphavirus and piscine orthoreovirus-1 infections in migrating salmon (Salmo salar L.) post-smolt in western Norway
(Peer reviewed; Journal article, 2023)Viral diseases are a serious problem in Atlantic salmon (Salmo salar L.) farming in Norway, often leading to reduced fish welfare and increased mortality. Disease outbreaks in salmon farms may lead to spread of viruses to ... -
Fluoride – a scoping review for Nordic Nutrition Recommendations 2023
(Peer reviewed; Journal article, 2023)Fluoride has a well-documented role in the prevention and treatment of dental caries, but the mechanism is attributed to local effects on the tooth enamel surface rather than systemic effects. Fluoride is not considered ... -
