A bio-economic analysis of harvest control rules for the Northeast Arctic cod fishery
(Journal article; Peer reviewed, 2012-12-12)Harvest control rules (HCRs) have been implemented for many fisheries worldwide. However, in most instances, those HCRs are not based on the explicit feedbacks between stock properties and economic considerations. This ... -
A biotest system for optimalization of environmental parameters for production of halibut fry
(ICES CM Documents;1987/F:21, Working paper, 1987)A system for controlled testing of different environmental parameters in seawater was made. Both the biotest system and an experimental setup using larvae of the Atlantic Halibut (Hippoglossus hippoglossus L.) are described. -
A brief history of climate – the northern seas from the Last Glacial Maximum to global warming
(Journal article; Peer reviewed, 2014-08-06)The understanding of climate and climate change is fundamentally concerned with two things: a well-defined and sufficiently complete climate record to be explained, for example of observed temperature, and a relevant ... -
A catch limitation device to avoid excessive catches in the blue whiting (Micromesistius poutassou) Northeast Atlantic pelagic trawl fishery
(Peer reviewed; Journal article, 2022)Blue whiting (Micromesistius poutassou) is harvested in the Northeast Atlantic by a multinational fleet of pelagic trawlers. Occasionally, vessels take catches which exceed their remaining holding capacity and in extreme ... -
A chromosome-level assembly of the Atlantic herring genome-detection of a supergene and other signals of selection
(Journal article; Peer reviewed, 2019)The Atlantic herring is a model species for exploring the genetic basis for ecological adaptation, due to its huge population size and extremely low genetic differentiation at selectively neutral loci. However, such studies ... -
A combination of genetic and phenotypic characterization of spring- and autumn-spawning herring suggests gene flow between populations
(Peer reviewed; Journal article, 2020)Atlantic herring (Clupea harengus) has complex population structure and dynamics including diverse life histories and spawning times with spring and autumn spawning as the most common modes. Originally, spawning herring ... -
A combined fish larval, phytoplankton and oceanographic survey in the Skagerrak and the Kattegat in April 1983
(ICES CM Documents;1983/L:26, Working paper, 1983) -
A common garden design reveals population-specific variability in potential impacts of hybridization between populations of farmed and wild Atlantic salmon, Salmo salar L.
(Journal article; Peer reviewed, 2016-01-27)Released individuals can have negative impacts on native populations through various mechanisms, including competition, disease transfer and introduction of maladapted gene complexes. Previous studies indicate that the ... -
A common-garden experiment to quantify evolutionary processes in copepods: the case of emamectin benzoate resistance in the parasitic sea louse Lepeophtheirus salmonis
(Journal article; Peer reviewed, 2014-05-19)Background The development of pesticide resistance represents a global challenge to food production. Specifically for the Atlantic salmon aquaculture industry, parasitic sea lice and their developing resistance to delousing ... -
A comparative study of quality and safety of Atlantic cod (Gadus morhua) fillets during cold storage, as affected by different thawing methods of pre-rigor frozen headed and gutted fish
(Journal article; Peer reviewed, 2017)The catch of marine whitefish is typically seasonal, whereas the land‐based processing industry has a need for all‐year stable supply of raw materials. This challenge can be met by applying fish frozen at sea. When using ... -
A comparison between three Atlantic salmon river stocks; using classical population genetics, differences in life history traits and performance in sea ranching
(ICES CM Documents;1997/P:13, Working paper, 1997)Characterisation of stocks is essential for fisheries and environmental management in order to conserve genetic diversity. However, classical populationgenetic methods frequently fail to document stock differences. In ... -
A comparison of biological trends from four marine ecosystems: synchronies, differences, and commonalities
(ICES CM documents;2007/D:09, Working paper, 2007) -
A comparison of community and trophic structure in five marine ecosystems based on energy budgets and system metrics
(ICES CM documents;2007/D:11, Working paper, 2007)As part of the international MENU collaboration, energy budget models for five marine ecosystems were compared to identify differences and similarities in trophic and community characteristics across ecosystems. We examined ... -
A comparison of gene transcription profiles of domesticated and wild Atlantic salmon (Salmo salar L.) at early life stages, reared under controlled conditions
(Journal article; Peer reviewed, 2014-10-09)Background Atlantic salmon have been subject to domestication for approximately ten generations, beginning in the early 1970s. This process of artificial selection will have created various genetic differences between ... -
A comparison of growth rate of halibut larvae (Hippoglossus hippoglossus L.) fed wild zooplankton and enriched Artemia
(ICES CM Documents;1990/F:60, Working paper, 1990)Halibut larvae at an age of 267 day degrees post hatching, were reared through first feeding, outdoors in 100 l plastic bags. There were three feeding regimes: wild zooplankton, Artemia enriched on the algae Isochrysis ... -
A comprehensive assessment of fish and other seafood in the Norwegian diet.
(VKM Report, Research report, 2006) -
A conservation plan for Atlantic salmon (Salmo salar) and anadromous brown trout (Salmo trutta) in a region with intensive industrial use of aquatic habitats, the Hardangerfjord, western Norway
(Journal article; Peer reviewed, 2013-10-15)Extensive use of aquatic habitats, mainly for hydropower and aquaculture, has a negative impact on anadromous salmonid populations of the Hardangerfjord region, western Norway. High infection levels of salmon lice, and ... -
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 ... -
A cross-ecosystem comparison of temporal variability in recruitment of functionally analogous fish stocks
(ICES CM documents;2007/D:10, Working paper, 2007)As part of the international MENU collaboration, variability in temporal patterns of recruitment and spawning stock were compared among functionally analogous species from four marine ecosystems including the Gulf of ...
