Change in Fish Community Structure in the Barents Sea
(Journal article; Peer reviewed, 2013-04-29)Change in oceanographic conditions causes structural alterations in marine fish communities, but this effect may go undetected as most monitoring programs until recently mainly have focused on oceanography and commercial ... -
Changes in baseline growth and maturation parameters of Northwest Atlantic porbeagle, Lamna nasus, following heavy exploitation
(Journal article; Peer reviewed, 2007)We tested for density-dependent changes in growth and maturation of Northwest Atlantic porbeagle (Lamna nasus) after the population declined by 75%-80% from fishing. Vertebrae and reproductive data collected from the virgin ... -
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 blood testosterone and progesterone concentrations of the North Atlantic minke whale (Balaenoptera acutorostrata) during the feeding season
(Journal article; Peer reviewed, 2004)An opportunity to study seasonal changes of sex hormones in the North Atlantic minke whale (common minke whale, Balaenoptera acutorostrata) arose when we obtained access to fresh postmortem blood samples from 104 females ... -
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 growth of Northeast Arctic cod in relation to food consumption in 1984-1988
(ICES Marine Science Symposia, Journal article; Peer reviewed, 1991)From 1984 to 1988 the average weight of cod (Gadus morhun) by age group in the Northeast Arctic stock was reduced by about 60% in most age groups. During the same period, the estimated individual food consumption by age ... -
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 plasma and liver glutathione levels in Atlantic salmon Salmo salar suffering from infectious salmon anemia (ISA)
(Journal article; Peer reviewed, 1992-10-08)The levels of reduced glutathione (GSH) in plasma and liver in healthy Atlantic salmon Salmo salar and salmon suffering from infectious salmon anaemia (ISA) were measured using high-performance liquid chromatography (HPLC). ... -
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 the relationship between sea temperature and recruitment of cod, haddock and herring in the Barents Sea
(Journal article; Peer reviewed, 2013-06-14)Cod, haddock and herring in the Barents Sea have strongly variable recruitment. For these three stocks, earlier studies have suggested a high correlation between their recruitment and a positive relationship between high ... -
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 ... -

Characterisation of the capsid protein gene from a nodavirus strain affecting the Atlantic halibut Hippoglossus hippoglossus and design of an optimal reverse-transcriptase polymerase chain reaction (RT-PCR) detection assay
(Journal article; Peer reviewed, 2000-01-14)1349 nucleotide fragment of the RNA2 from a nodavirus affecting Atlantic halibut Hippoglossus hippoglossus was characterised and the nuclotide sequence (accession no, AJ245641) was employed to develop an optimal ... -
Characterisation of two vitellogenins in the salmon louse Lepeophtheirus salmonis: molecular, functional and evolutional analysis
(Journal article; Peer reviewed, 2011-05-09)The salmon louse Lepeophtheirus salmonis Krøyer affects a variety of wild salmonoid hosts, but is also an important pest in aquaculture, which is a globally important and rapidly growing industry. Salmon lice have large ... -
