Model-informed classification of broadband acoustic backscatter from zooplankton in an in situ mesocosm
(Peer reviewed; Journal article, 2023)Classification of zooplankton to species with broadband echosounder data could increase the taxonomic resolution of acoustic surveys and reduce the dependence on net and trawl samples for ‘ground truthing’. Supervised ... -
Methionine: An Indispensable Amino Acid in Cellular Metabolism and Health of Atlantic Salmon
(Peer reviewed; Journal article, 2023)Methionine is an indispensable amino acid with an important role as the main methyl donor in cellular metabolism for both fish and mammals. Metabolization of methionine to the methyl donor S-adenosylmethionine (SAM) has ... -
A review of the genus Muusoctopus (Cephalopoda: Octopoda) from Arctic waters
(Peer reviewed; Journal article, 2023)We report two Arctic species of incirrate octopods new to science. One is formally described here as Muusoctopus aegir Golikov, Gudmundsson & Sabirov sp. nov. while the other, Muusoctopus sp. 1, is not formally described ... -
Evolutionary predictions for a parasite metapopulation: Modelling salmon louse resistance to pest controls in aquaculture
(Peer reviewed; Journal article, 2023)Pests often evolve resistance to pest controls used in agriculture and aquaculture. The rate of pest adaptation is influenced by the type of control, the selective pressure it imposes, and the gene flow between farms. By ... -
Environmental controls on macrozooplankton and fish distributions over diurnal to seasonal time scales in the northern Barents Sea
(Peer reviewed; Journal article, 2023)We present acoustic observations obtained by bottom mounted echosounders at two locations in the northern Barents Sea and a third on the northern continental slope of the Barents Sea. Data collected over a period of ... -
Multi-tissue proteogenomic analysis for mechanistic toxicology studies in non-model species
(Peer reviewed; Journal article, 2023)New approach methodologies (NAM), including omics and in vitro approaches, are contributing to the implementation of 3R (reduction, refinement and replacement) strategies in regulatory science and risk assessment. In this ... -
Toxicometabolomics as a tool for next generation environmental risk assessment
(Peer reviewed; Journal article, 2023)Traditionally applied methodology in environmental risk assessment (ERA) has fallen out of step with technological advancements and regulatory requirements, challenging effectiveness and accuracy of the assessments. Extensive ... -
Thin and transient meltwater layers and false bottoms in the Arctic sea ice pack-Recent insights on these historically overlooked features
(Peer reviewed; Journal article, 2023)The rapid melt of snow and sea ice during the Arctic summer provides a significant source of low-salinity meltwater to the surface ocean on the local scale. The accumulation of this meltwater on, under, and around sea ice ... -
Hydrography, inorganic nutrients and chlorophyll a linked to sea ice cover in the Atlantic Water inflow region north of Svalbard
(Peer reviewed; Journal article, 2023) -
Crude oil exposure of early life stages of Atlantic haddock suggests threshold levels for developmental toxicity as low as 0.1 μg total polyaromatic hydrocarbon (TPAH)/L
(Peer reviewed; Journal article, 2023)Atlantic haddock (Melanogrammus aeglefinus) embryos bind dispersed crude oil droplets to the eggshell and are consequently highly susceptible to toxicity from spilled oil. We established thresholds for developmental toxicity ... -
Validating Finescale Parameterizations for the Eastern Arctic Ocean Internal Wave Field
(Peer reviewed; Journal article, 2023)In the Arctic Ocean, vertical transport of heat by turbulent mixing is ultimately coupled to the sea-ice cover, with immediate and far-reaching impacts on the climate and ecosystem. Unfortunately, direct observations of ... -
Repeated exposure affects susceptibility and responses of Atlantic salmon (Salmo salar) towards the ectoparasitic salmon lice (Lepeophtheirus salmonis)
(Peer reviewed; Journal article, 2023)Atlantic salmon (Salmo salar) is repeatedly exposed to and infected with ectoparasitic salmon lice (Lepeophtheirus salmonis) both in farms and in nature. However, this is not reflected in laboratory experiments where fish ... -
Diffusive and advective cross-frontal fluxes of inorganic nutrients and dissolved inorganic carbon in the Barents Sea in autumn
(Peer reviewed; Journal article, 2023)The Atlantic Water, entering the Arctic through the Barents Sea and Fram Strait, is the main source of nutrients in the Arctic Ocean. The Barents Sea is divided by the Polar Front into an Atlantic-dominated domain in the ... -
Oceanographic connectivity explains the intra-specific diversity of mangrove forests at global scales
(Peer reviewed; Journal article, 2023)The distribution of mangrove intra-specific biodiversity can be structured by historical demographic processes that enhance or limit effective population sizes. Oceanographic connectivity (OC) may further structure ... -
A contrastive learning approach for individual re-identification in a wild fish population
(Peer reviewed; Journal article, 2023)In both terrestrial and marine ecology, physical tagging is a frequently used method to study population dynamics and behavior. However, such tagging techniques are increasingly being replaced by individual re-identification ... -
Comparative assessment of food safety regulations and standards for arsenic, cadmium, lead, mercury and iodine in macroalgae used as food and feed in China and Europe
(Peer reviewed; Journal article, 2023)Seaweed, or macroalgae has traditionally been part of Asian cuisine for decades and is also becoming increasingly popular as a food source in Europe and other Western countries. However, seaweed can accumulate elements ... -
Genomic disturbance of vitellogenin 2 (vtg2) leads to vitellin membrane deficiencies and significant mortalities at early stages of embryonic development in zebrafish (Danio rerio)
(Peer reviewed; Journal article, 2023)The specific functions and essentiality of type II vitellogenin (Vtg2) in early zebrafish development were investigated in this study. A vtg2-mutant zebrafish line was produced and effects of genomic disturbance were ... -
Epidemiological cut-off values for Vibrio anguillarum MIC and disc diffusion data generated by standardised methods
(Peer reviewed; Journal article, 2023)This work aims to generate the data needed to set epidemiological cut-off values for minimum inhibitory concentration (MIC) and disc-diffusion zone measurements of Vibrio anguillarum. A total of 261 unique isolates were ... -
Caught in the trap: over half of the farmed Atlantic salmon removed from a wild spawning population in the period 2014−2018 were mature
(Peer reviewed; Journal article, 2023)Whilst aquaculture continues its global expansion, containment of fish in sea cages remains a persistent environmental challenge. Within Atlantic salmon Salmo salar farming, widespread escapes over several decades have ... -
Comparative resistome analysis of Aeromonas species in aquaculture reveals antibiotic resistance patterns and phylogeographic distribution
(Peer reviewed; Journal article, 2023)The overuse of antibiotics in aquaculture drives the emergence of multi-drug-resistant bacteria, and antibiotic-resistant genes (ARGs) can be disseminated to other bacteria through vertical- and horizontal gene transfer ...
