Ontogeny-Specific Skeletal Deformities in Atlantic Haddock Caused by Larval Oil Exposure
(Peer reviewed; Journal article, 2021)Bone deformities are one of the main effects of crude oil exposure in marine fish larvae. Craniofacial and jaw deformities, if severe enough, may restrict feeding and ultimately kill the developing larvae. This study aimed ... -
Ocean acidification state variability of the Atlantic Arctic Ocean around northern Svalbard
(Peer reviewed; Journal article, 2021)The Svalbard shelf and Atlantic Arctic Ocean are a transition zone between northward flowing Atlantic Water and ice-covered waters of the Arctic. Effects of regional ocean warming, sea ice loss and greater influence of ... -
Antibacterial treatment of lumpfish (Cyclopterus lumpus) experimentally challenged with Vibrio anguillarum, atypical Aeromonas salmonicida and Pasteurella atlantica
(Peer reviewed; Journal article, 2021)Lumpfish is a novel farmed species used as cleaner fish for the removal of lice from farmed salmon. As often with new, farmed species, there are challenges with bacterial infections. The frequency of prescription of ... -
Where and How the East Madagascar Current Retroflection Originates?
(Peer reviewed; Journal article, 2021)The East Madagascar Current (EMC) is one of the western boundary currents of the South Indian Ocean. As such, it plays an important role in the climate system by transporting water and heat toward the pole and recirculating ... -
The effect of fasting period on swimming performance, blood parameters and stress recovery in Atlantic salmon post molts
(Peer reviewed; Journal article, 2021)Individually tagged Atlantic salmon postsmolts (≈1200 g, 46 cm) reared in triplicate indoor holding tanks were fasted for 8 weeks at 12 °C and subsequently refed for 5 weeks, whereafter they were transferred to triplicate ... -
Full production cycle, commercial scale culture of salmon in submerged sea-cages with air domes reduces lice infestation, but creates production and welfare challenges
(Peer reviewed; Journal article, 2021)Structural modification of sea cages is continually changing to counter major production issues associated with commercial salmon farming. For example, snorkels and skirts are added to cages to reduce salmon lice infestations, ... -
Genomic characterization of multidrug-resistant Bacillus toyonensis strain 4HC1 isolated from marine plastic in Norway
(Peer reviewed; Journal article, 2021)Bacillus toyonensis is widespread in nature. Multidrug-resistant B. toyonensis strain 4HC1 was isolated from polyethylene submerged in the water column near a beach in Øygarden, Norway. We analysed the whole genome sequence ... -
Submerged cage aquaculture of marine fish: a review of the biological challenges and opportunities
(Peer reviewed; Journal article, 2021)Surface-based cages are the dominant production technology for the marine finfish aquaculture industry. However, issues such as extreme weather events, poor environmental conditions, interactions with parasites, and conflicts ... -
Population structure of European sprat (Sprattus sprattus) in the Greater North Sea ecoregion revealed by otolith shape analysis
(Peer reviewed; Journal article, 2021)A successful discrimination of fish populations is essential for sustainable management and assessment. Otolith shape analysis has been used on several species to reveal their population structure. Our aim was to use the ... -
Autonomous Surface and Underwater Vehicles as Effective Ecosystem Monitoring and Research Platforms in the Arctic—The Glider Project
(Peer reviewed; Journal article, 2021)Effective ocean management requires integrated and sustainable ocean observing systems enabling us to map and understand ecosystem properties and the effects of human activities. Autonomous subsurface and surface vehicles, ... -
Ice-Associated Amphipods in a Pan-Arctic Scenario of Declining Sea Ice
(Peer reviewed; Journal article, 2021)Sea-ice macrofauna includes ice amphipods and benthic amphipods, as well as mysids. Amphipods are important components of the sympagic food web, which is fuelled by the production of ice algae. Data on the diversity of ... -

Skilful prediction of cod stocks in the North and Barents Sea a decade in advance
(Peer reviewed; Journal article, 2021)Reliable information about the future state of the ocean and fish stocks is necessary for informed decision-making by fisheries scientists, managers and the industry. However, decadal regional ocean climate and fish stock ... -
The impact of surface currents on the wave climate in narrow fjords
(Peer reviewed; Journal article, 2021)This study investigates the effect of surface currents on wind-generated waves in a complex coastal system with narrow fjords. The simulations are based on a phase-averaged wave model forced with surface currents from a ... -
Seasonal Variability in the Zooplankton Community Structure in a Sub-Arctic Fjord as Revealed by Morphological and Molecular Approaches
(Peer reviewed; Journal article, 2021)Phyto- and zooplankton in Arctic and sub-Arctic seas show very strong seasonal changes in diversity and biomass. Here we document the seasonal variability in the mesozooplankton community structure in a sub-Arctic fjord ... -
High Species Richness and Extremely Low Abundance of Cumacean Communities Along the Shelf and Slope of the Gulf of Guinea (West Africa)
(Peer reviewed; Journal article, 2021)The Gulf of Guinea belongs to the most scarcely sampled marine basins in the oceans of the world. We have analyzed diversity and distribution patterns of cumacean communities on the shelf and slope, along the coast of ... -
Impact of dietary level and ratio of n-6 and n-3 fatty acids on disease progression and mRNA expression of immune and inflammatory markers in Atlantic salmon (Salmo salar) challenged with Paramoeba perurans
(Peer reviewed; Journal article, 2021)The aim of the study was to investigate the influence of dietary level and ratio of n-6/n-3 fatty acids (FA) on growth, disease progression and expression of immune and inflammatory markers in Atlantic salmon (Salmo salar) ... -
Diets of the Barents Sea cod (Gadus morhua) from the 1930s to 2018
(Peer reviewed; Journal article, 2021)A new dataset on the diet of Atlantic cod in the Barents Sea from the 1930s to the present day has been compiled to produce one of the largest fish diet datasets available globally. Atlantic cod is one of the most ecologically ... -
Leucine did not stimulate growth and accretion in either stressed or unstressed Atlantic salmon
(Peer reviewed; Journal article, 2021)The aim of the current trial was to test whether leucine affected growth and accretion including test any effects on leucine upon stress. Quadruplicate tanks each containing 50 Atlantic salmon (Salmo salar) (mean start ... -
The information continuum model of evolution
(Peer reviewed; Journal article, 2021)Most biologists agree that evolution is contingent on inherited information shaped by natural selection. This apparent consensus could be taken to indicate agreement on the forces shaping evolution, but vivid discussions ...
