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) -
Quality of fish sludge as fertiliser to spring cereals: Nitrogen effects and environmental pollutants
(Peer reviewed; Journal article, 2023)The aim of this study was to contribute to development of organic fertiliser products based on fish sludge (i.e. feed residues and faeces) from farmed smolt. Four dried fish sludge products, one liquid digestate after ... -
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 ... -
Quantification of trophic interactions in the Norwegian Sea pelagic food-web over multiple decades
(Peer reviewed; Journal article, 2022)While ecosystem-based fisheries management calls for explicit accounting for interactions between exploited populations and their environment, moving from single species to ecosystem-level assessment is a significant ... -
Quantification of wide-area norwegian spring-spawning herring population density with ocean acoustic waveguide remote sensing (OAWRS)
(Peer reviewed; Journal article, 2021)Norwegian spring-spawning herring are a critical economic resource for multiple nations in the North Atlantic and a keystone species of the Nordic Seas ecosystem. Given the wide areas that the herring occupy, it is difficult ... -
Quantifying diets for small pelagic fish: effects of weight versus occurrence methods and sampling effort
(Peer reviewed; Journal article, 2023)In the Norwegian Sea, assessment of diet composition relies on annual cruise activity combined with visual identification and weight determination of prey from fish stomachs. This weight-based method is labour intensive, ... -
Quantifying the Detection Sensitivity and Precision of qPCR and ddPCR Mechanisms for eDNA Samples
(Peer reviewed; Journal article, 2024)Environmental DNA (eDNA) detection employing quantitative PCR (qPCR) and droplet digital PCR (ddPCR) offers a non-invasive and efficient approach for monitoring aquatic organisms. Accurate and sensitive quantification of ... -
Quantifying the effects of sample size and species distribution on the precision and accuracy of abundance estimates from bottom-trawl surveys in the Gulf of Alaska
(Peer reviewed; Journal article, 2024)We assessed the effect of survey effort reduction on the accuracy and precision of estimates of abundance for 4 commercially or ecologically important species with differing distributions observed in a bottom-trawl survey ... -
Quantifying the escape mortality of trawl caught Antarctic krill (Euphausia superba)
(CCAMLR;WG-EMM-16/04, Conference object, 2016) -
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 ... -
Quantifying zoobenthic blue carbon storage across habitats within the Arctic’s Barents Sea
(Peer reviewed; Journal article, 2023)The Arctic sea ice extent in September (when it is at its lowest) has declined 13% Q10 per decade, and the Arctic Ocean is becoming a more Atlantic-influenced system. Rapid climate-forced changes are taking place in many ... -
Quantitative molecular detection of larval Atlantic herring (Clupea harengus) in stomach contents of Atlantic mackerel (Scomber scombrus) marks regions of predation pressure
(Peer reviewed; Journal article, 2021)Mortality rates in the early life-history stages of fishes are generally high yet identifying the causes remain unclear. Faltering recruitment rates of Atlantic herring (Clupea harengus) in the Norwegian Sea indicate a ... -
Quantitative processing of broadband data as implemented in a scientific split-beam echosounder
(Peer reviewed; Journal article, 2023)The use of quantitative broadband echosounders for biological studies and surveys can offer considerable advantages over narrowband echosounders. These include improved spectral-based target identification and significantly ... -
Quantitative proteome profiling reveals molecular hallmarks of egg quality in Atlantic halibut: impairments of transcription and protein folding impede protein and energy homeostasis during early development
(Peer reviewed; Journal article, 2022)Tandem mass tag spectrometry (TMT labeling-LC-MS/MS) was utilized to examine the global proteomes of Atlantic halibut eggs at the 1-cell-stage post fertilization. Comparisons were made between eggs judged to be of good ... -
The quest for seafloor macrolitter: A critical review of background knowledge, current methods and future prospects
(Peer reviewed; Journal article, 2021)The seafloor covers some 70% of the Earth's surface and has been recognised as a major sink for marine litter. Still, litter on the seafloor is the least investigated fraction of marine litter, which is not surprising as ... -
