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 ... -
Still Arctic? — The changing Barents Sea
(Peer reviewed; Journal article, 2023)The Barents Sea is one of the Polar regions where current climate and ecosystem change is most pronounced. Here we review the current state of knowledge of the physical, chemical and biological systems in the Barents Sea. ... -
Impacts of glacial and sea-ice meltwater, primary production and ocean CO2 uptake on ocean acidification state of waters by the 79 North Glacier and northeast Greenland shelf
(Peer reviewed; Journal article, 2023)The waters adjacent to the Nioghalvfjerdsbræ (79 North Glacier, 79NG) are influenced by Greenland Ice Sheet (GrIS) melt, sea-ice meltwater, and waters on the adjacent northeast Greenland shelf (NEGS). We investigated ocean ... -
Quick and efficient microplastic isolation from fatty fish tissues by surfactant-enhanced alkaline digestion
(Peer reviewed; Journal article, 2023)For monitoring microplastic contamination in fish tissues, tissue digestion into filterable components prior to microplastic identification and quantification should be quick and efficient, providing satisfying microplastic ... -
The evolving story of catadromy in the European eel (Anguilla anguilla)
(Peer reviewed; Journal article, 2023)Anguillid eels were once considered to be the classic example of catadromy. However, alternative life cycles have been reported, including skipping the freshwater phase and habitat shifting between fresh, brackish, and ... -
Pre-fertilization gamete thermal environment influences reproductive success, unmasking opposing sex-specific responses in Atlantic salmon (Salmo salar)
(Peer reviewed; Journal article, 2023)The environment gametes perform in just before fertilization is increasingly recognized to affect offspring fitness, yet the contributions of male and female gametes and their adaptive significance remain largely unexplored. ... -
Experimental transmission of piscine orthoreovirus-1 (PRV-1) in different life stages of Atlantic salmon (Salmo salar) and brown trout (Salmo trutta)
(Peer reviewed; Journal article, 2023)Piscine orthoreovirus -1 (PRV-1) causes the disease heart and skeletal muscle inflammation (HSMI) in farmed Atlantic salmon, and the virus has been detected in wild anadromous Atlantic salmon and brown trout. However, the ... -
Genomic insights into Enterococcus faecium isolates from marine bivalves highlight One Health concerns and healthcare linkages
(Peer reviewed; Journal article, 2023)Enterococci, especially Enterococcus faecium, are one of today’s leading causes of multidrug-resistant infections in hospital settings. The marine environment may harbour enterococci, but its role as an evolutionary niche ... -
Unveiling the potential of proteomics in addressing food and feed safety challenges
(Peer reviewed; Journal article, 2023)The food and feed sector in Europe is rapidly evolving to address contemporary challenges, striving for fairer, safer, greener and more sustainable food systems. This includes the exploration of new protein sources for ... -
Quantitative processing of broadband data as implemented in a scientific split-beam echosounder
(Peer reviewed; Journal article, 2023)The use of quantitative broadband echosounders for biological studies and surveys can offer considerable advantages over narrowband echosounders. These include improved spectral-based target identification and significantly ... -
