Quality issues related to the presence of the fish parasitic nematode Hysterothylacium aduncum in export shipments of fresh Northeast Arctic cod (Gadus morhua)
(Peer reviewed; Journal article, 2021) -
Quantification of bell-shaped size selectivity in shrimp trawl fisheries using square mesh panels and a sorting cone after a Nordmøre grid
(Peer reviewed; Journal article, 2019)Shrimp trawlers in the Barents Sea use a Nordmøre sorting grid ahead of a small-mesh codend to avoid bycatch while catching shrimps efficiently. However, small fish can still pass through the grid to enter the codend, which ... -
Quantification of defensive proteins in skin mucus of atlantic salmon using minimally invasive sampling and high-sensitivity elisa
(Peer reviewed; Journal article, 2020)Protocols used to collect fish skin mucus may inadvertently compromise the sampled fish or the resulting sample. Here, we used three methods (wiping, scraping, and absorption) to collect skin mucus from Atlantic salmon and ... -
Quantification of eDNA to map the distribution of cold-water coral reefs
(Peer reviewed; Journal article, 2020)An effective management of vulnerable marine ecosystems is dependent on thorough knowledge of their location. Multibeam bathymetric mapping and targeted remotely operated vehicle (ROV) surveys are currently used to map ... -
Quantification of gear inflicted damages on trawl-caught haddock in the Northeast Atlantic fishery
(Peer reviewed; Journal article, 2020)External damages are indicators of the overall quality of fish and fish welfare. Haddock is an important commercial species widespread in the North Atlantic, but few studies related to quality have been carried out on this ... -
Quantifying the escape mortality of trawl caught Antarctic krill (Euphausia superba)

Quantifying the Escape Mortality of Trawl Caught Antarctic Krill (Euphausia superba)
(Journal article; Peer reviewed, 2016-09-13)Antarctic krill (Euphausia superba) is an abundant fishery resource, the harvest levels of which are expected to increase. However, many of the length classes of krill can escape through commonly used commercial trawl mesh ... -
Quantifying the Ocean, Freshwater and Human Effects on Year-to-Year Variability of One-Sea-Winter Atlantic Salmon Angled in Multiple Norwegian Rivers
(Journal article; Peer reviewed, 2011)Many Atlantic salmon, Salmo salar, populations are decreasing throughout the species' distributional range probably due to several factors acting in concert. A number of studies have documented the influence of freshwater ... -
Rainbow trout Oncorhynchus mykiss skin responses to salmon louse Lepeophtheirus salmonis: From copepodid to adult stage
(Peer reviewed; Journal article, 2020)The marine crustacean Lepeophtheirus salmonis (salmon louse) is a common ectoparasite of wild and farmed salmonids. The parasite has a complex ontogeny comprising eight instars. The planktonic copepodid stage settles on ... -
A ranking method of chemical substances in foods for prioritisation of monitoring, based on health risk and knowledge gaps
(Peer reviewed; Journal article, 2020)Chemical contaminants are present in all foods. Data on the occurrence of contaminants in foods that are often consumed or contain high contaminant concentrations are critical for the estimation of exposure and evaluation ... -
Ranking of substances for monitoring in foods, drinks and dietary supplements - based on risk and knowledge gaps
(VKM Report, Research report, 2019) -
Rapid climate-driven circulation changes threaten conservation of endangered north atlantic right whales
(Journal article; Peer reviewed, 2019)As climate trends accelerate, ecosystems will be pushed rapidly into new states, reducing the potential efficacy of conservation strategies based on historical patterns. In the Gulf of Maine, climate-driven changes have ... -
Rapid life-history evolution in a wild Daphnia pulex population in response to novel size-dependent predation
(Peer reviewed; Journal article, 2020)The effect of size-selective predation on prey communities and their traits is well documented, but the relative roles of genetic adaptation and phenotypic plasticity continue to be debated. We looked for evidence of genetic ... -
Rapport - Forsøksfiske etter mesopelagiske arter : M/S Ligrunn, september 2019
(Rapport fra havforskningen;2019 - 56, Research report, 2019)De siste 50 år har det vært spredte forsøk på høsting av mesopelagisk fisk. Etter globalt rekordestimat av denne ressursen, ble det rundt 2015 ny interesse for å utvikle et fiskeri etter mesopelagiske arter. Havforskning ... -

Reaction norm analysis reveals rapid shifts toward delayed maturation in harvested Lake Erie yellow perch (Perca flavescens)
(Journal article; Peer reviewed, 2019)Harvested marine fish stocks often show a rapid and substantial decline in the age and size at maturation. Such changes can arise from multiple processes including fisheries‐induced evolution, phenotypic plasticity, and ... -
“Real-time” genetic monitoring of a commercial fishery on the doorstep of an MPA reveals unique insights into the interaction between coastal and migratory forms of the Atlantic cod
(Journal article; Peer reviewed, 2017)With the decline of many of the world’s fisheries, increased regulation, including marine protected areas (MPA), forms an increasingly important role in promoting sustainable resource use. Here, we present a novel “real-time” ... -

Recent trend reversal for declining European seagrass meadows
(Journal article; Peer reviewed, 2019)Seagrass meadows, key ecosystems supporting fisheries, carbon sequestration and coastal protection, are globally threatened. In Europe, loss and recovery of seagrasses are reported, but the changes in extent and density ...
