Seasonal variations in mercury, cadmium, lead and arsenic species in Norwegian blue mussels (Mytilus edulis L.) – Assessing the influence of biological and environmental factors
(Peer reviewed; Journal article, 2023)Blue mussels (Mytilus edulis L.) can accumulate undesirable substances, including the potentially toxic elements (PTEs) cadmium (Cd), mercury, (Hg), lead (Pb), arsenic (As) and As species. In this study, the levels of PTEs ... -
Seasonality of marine calcifiers in the northern Barents Sea: Spatiotemporal distribution of planktonic foraminifers and shelled pteropods and their contribution to carbon dynamics
(Peer reviewed; Journal article, 2023)The Barents Sea is presently undergoing rapid warming and the sea-ice edge and the productive zones are retreating northward at accelerating rates. Planktonic foraminifers and shelled pteropods are ubiquitous marine ... -
Seasonality of the Physical and Biogeochemical Hydrography in the Inflow to the Arctic Ocean Through Fram Strait

Seatrout (Salmo trutta) is a natural host for Parvicapsula pseudobranchicola (Myxozoa, Myxosporea), an important pathogen of farmed Atlantic salmon (Salmo salar)
(Journal article; Peer reviewed, 2015-04-10)Background: Parvicapsula pseudobranchicola (Myxozoa) causes widespread infections in farmed Atlantic salmon in northern Norway. Heavily infected salmon become runts, probably due to vision impairment or blindness. The salmon ... -
Seawater from Bergen harbor is a reservoir of conjugative multidrug-resistance plasmids carrying genes for virulence
(Peer reviewed; Journal article, 2023)Aquatic environments play important roles in the dissemination of clinically-relevant antibiotic resistance genes (ARGs) and pathogens. Limited knowledge exists about the prevalence of clinically-relevant acquired resistance ... -
Seaweed forests are carbon sinks that may help mitigate CO2 emissions: a comment on Gallagher et al. (2022)
(Peer reviewed; Journal article, 2023)Recently, Gallagher et al. (2022) suggested that seaweed ecosystems are net heterotrophic carbon sources due to CO2 released from the consumption of external subsidies. Here we outline several flaws in their argument, which ... -
Sedimentation of particulate organic matter and silicium during spring and summer in Lindaspollene, Western Norway
(Journal article; Peer reviewed, 1986-04-24)Sedimentation of organic and inorganic matter was determined at 18, 38, 70 and 85 m between 17 March and 8 October 1982, m the land-locked flord Llndespollene Rates of sedimentation were highest dunng spnng with 2 peaks ... -
Selection on fish personality differs between a no-take marine reserve and fished areas
(Peer reviewed; Journal article, 2021)Marine reserves can protect fish populations by increasing abundance and body size, but less is known about the effect of protection on fish behaviour. We looked for individual consistency in movement behaviours of sea ... -
Selective flatfish seine: A knee-high demersal seine barely catches cod
(Peer reviewed; Journal article, 2019)Norwegian coastal cod (Gadus morhua) protection restricts the use of active fishing gears. Demersal seines, acknowledged as being efficient for targeting flatfish, are therefore largely excluded from the fjords. To exploit ... -
Selective isolation of Arctic marine actinobacteria and a down-scaled fermentation and extraction strategy for identifying bioactive compounds
(Peer reviewed; Journal article, 2022)Actinobacteria are among the most prolific producers of bioactive secondary metabolites. In order to collect Arctic marine bacteria for the discovery of new bioactive metabolites, actinobacteria were selectively isolated ... -

Selenium and selenium species in feeds and muscle tissue of Atlantic salmon
(Journal article; Peer reviewed, 2018)Selenium (Se) is an essential element for animals, including fish. Due to changes in feed composition for Atlantic salmon (Salmo salar), it may be necessary to supplement feeds with Se. In the present work, the transfer ... -
Semi-supervised target classification in multi-frequency echosounder data
(Peer reviewed; Journal article, 2021)Acoustic target classification in multi-frequency echosounder data is a major interest for the marine ecosystem and fishery management since it can potentially estimate the abundance or biomass of the species. A key problem ... -
Sensitivity of the Norwegian and Barents Sea Atlantis end-to-end ecosystem model to parameter perturbations of key species
(Journal article; Peer reviewed, 2019)Using end-to-end models for ecosystem-based management requires knowledge of the structure, uncertainty and sensitivity of the model. The Norwegian and Barents Seas (NoBa) Atlantis model was implemented for use in ‘what ... -
Sensitivity towards elevated pCO2 in great scallop (Pecten maximus Lamarck) embryos and fed larvae

Sentinels in Salmon Aquaculture: Heart Rates Across Seasons and During Crowding Events
(Peer reviewed; Journal article, 2021)Advances in tag technology now make it possible to monitor the behavior of small groups of individual fish as bioindicators of population wellbeing in commercial aquaculture settings. For example, tags may detect unusual ... -
Sequence variation in four mitochondrial genes of the salmon louse Lepeophtheirus salmonis
(Journal article; Peer reviewed, 2006-03-02)A total of 210 Lepeophtheirus salmonis collected from 7 locations (Scotland, Russia, Canada, Japan and 3 locations in Norway), were screened for sequence variation in 4 mitochondrial genes; ATPase subunit 6 (A6), Cytochrome ... -
Sequential codend improves quality of trawlcaught cod
(Peer reviewed; Journal article, 2018)Trawl-caught fish are frequently associated with deteriorated catch quality. This study presents a new dual sequential codend concept with the aim of improving the quality of trawl-caught fish by minimizing the frequency ... -
Sero- and genotyping of some marine aquatic birnavirus isolates from Norway
(Journal article; Peer reviewed, 1997-03-27)Twelve isolates of aquatic birnaviruses (9 field isolates from marine fish and shellfish and the Ab/A(3), Sp/A(2) and N1 strains) were serotyped using an immunodot assay. The assay with 17 monoclonal antibodies revealed ... -
