Caught in broad daylight: Topographic constraints of zooplankton depth distributions
(Journal article; Peer reviewed, 2018)For visual predators, sufficient light is critical for prey detection and capture. Because light decays exponentially with depth in aquatic systems, vertical movement has become a widespread strategy among zooplankton for ... -
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 ... -
Causal Drivers of Barents Sea Capelin(Mallotus villosus) Population Dynamics on Different Time Scales
(Journal article; Peer reviewed, 2017)The dynamics of marine populations are usually forced by biotic and abiotic factors occurring at different intensity levels and time scales. Deriving the time frame within which each factor has a causal influence is important ... -
Caveats with estimating natural mortality rates in stock assessment models using age aggregated catch data and abundance indices
(Peer reviewed; Journal article, 2021)We consider the challenge in estimating the natural mortality, M, in a standard statistical fish stock assessment model based on time series of catch- and abundance-at-age data. Though anecdotal evidence and empirical ... -
A century of fish growth in relation to climate change, population dynamics and exploitation
(Peer reviewed; Journal article, 2020)Marine ecosystems, particularly in high‐latitude regions such as the Arctic, have been significantly affected by human activities and contributions to climate change. Evaluating how fish populations responded to past changes ... -
Century-long cod otolith biochronology reveals individual growth plasticity in response to temperature
(Peer reviewed; Journal article, 2020)Otolith biochronologies combine growth records from individual fish to produce long-term growth sequences, which can help to disentangle individual from population-level responses to environmental variability. This study ... -
Challenges Ahead for a Rational Analysis of Vitamin D in Athletes
(Peer reviewed; Journal article, 2021)Vitamin D is an essential vitamin for the normal formation of bones and calcium absorption. It is synthesized into our body through sunlight exposure and obtained by consuming foods rich in vitamin D (e.g., fatty fish, ... -
Changes in benthic sediment conditions under an atlantic salmon farm at a deep, well-flushed coastal site
(Journal article; Peer reviewed, 2014-02-27)Along the Norwegian coastline, it is predicted that salmonid aquaculture will rapidly expand in the coming years, exceeding current production levels of 1.3 million t in 2012. This will result in increased interactions ... -
Changes in daylength and temperature from April until August for Atlantic salmon (Salmo salar) reared in sea cages, increase growth, and may cause consumption of antioxidants, onset of cataracts and increased oxidation of fillet astaxanthin
(Peer reviewed; Journal article, 2022)The hypothesis of the present study was that increased growth in spring, stimulated by increasing temperature and daylength, leads to oxidative stress in Atlantic salmon with accumulation of oxidation products in the tissues ... -
Changes in humpback whale song structure and complexity reveal a rapid evolution on a feeding ground in Northern Norway
(Peer reviewed; Journal article, 2022)Singing behaviour by male humpback whales (Megaptera novaeangliae) has traditionally been associated with low-latitude breeding grounds. However, in recent years, this vocal behaviour has been increasingly reported outside ... -
Changes in Sea-Ice Protist Diversity With Declining Sea Ice in the Arctic Ocean From the 1980s to 2010s
(Peer reviewed; Journal article, 2020)The large declines in Arctic sea-ice age and extent over the last decades could have altered the diversity of sea-ice associated unicellular eukaryotes (referred to as sea-ice protists). A time series from the Russian ... -
Changes in water temperature and oxygen: the effect of triploidy on performance and metabolism in large farmed Atlantic salmon
(Peer reviewed; Journal article, 2018) -
Changing fish distributions challenge the effective management of European fisheries.
(Journal article; Peer reviewed, 2020)Changes in fish distribution are being observed across the globe. In Europe's Common Fisheries Policy, the share of the catch of each fish stock is split among management areas using a fixed allocation key known as ‘Relative ... -
Changing nutritional seascapes of kelp forests
(Peer reviewed; Journal article, 2023)Ocean warming and short-term extreme events (e.g. marine heatwaves) are becoming more intense and frequent and have had major impacts on ecosystems. Seaweeds are foundational components of temperate reefs, providing nutrition ... -
Characterisation and expression analysis of the Atlantic halibut (Hippoglossus hippoglosssus L.) cytokines: IL-1β, IL-6, IL-11, IL-12β and IFNγ
(Journal article; Peer reviewed, 2012)Genes encoding the five Atlantic halibut (Hippoglossus hippoglossus L.) cytokines; interleukin (IL)-1β, IL-6, IL-11b, IL-12βc, and interferon (IFN) γ, were cloned and characterised at a molecular level. The genomic ... -
Characteristics of the Norwegian Coastal Current during years with high recruitment of Norwegian spring spawning herring (Clupea harengus L.)
(Journal article; Peer reviewed, 2015-12-04)Norwegian Spring Spawning herring (NSSH) Clupea harengus L. spawn on coastal banks along the west coast of Norway. The larvae are generally transported northward in the Norwegian Coastal Current (NCC) with many individuals ... -
Characterization of a novel RXR receptor in the salmon louse (Lepeophtheirus salmonis, Copepoda) regulating growth and female reproduction
(Journal article; Peer reviewed, 2015-02-14)Nuclear receptors have crucial roles in all metazoan animals as regulators of gene transcription. A wide range of studies have elucidated molecular and biological significance of nuclear receptors but there are still a ... -
Characterization of Pseudoterranova ceticola (Nematoda: Anisakidae) larvae from meso/bathypelagic fishes off Macaronesia (NW Africa waters)
(Peer reviewed; Journal article, 2022)The genus Pseudoterranova includes parasite species of cetaceans and pinnipeds. The third stage larva (L3) of seal-infecting species occur in second intermediate or paratenic fish hosts mainly in neritic waters. This study ... -
