Updating the Antarctic krill biomass estimates for CCAMLR Subareas 48.1 to 48.4 using available data
(;WG-EMM-15/28, Research report, 2015)We present a novel index of Antarctic krill biomass in CCAMLR subareas 48.1 to 48.4, based on data from scientific nets and covering the years between 2000 and 2011. The annual biomass variation was significant (CV=73%) ... -
Upeneus floros, a new goatfish from South Africa and Mozambique, with updated taxonomic accounts for U. guttatus and U. pori and a key to Western Indian Ocean Upeneus species (Mullidae)
(Peer reviewed; Journal article, 2020)The highly diverse goatfish genus Upeneus (Mullidae) requires enhanced attention regarding the possible occurrence of undescribed species in insufficiently explored regions. This study focuses on the South-Western Indian ... -
Uptake of sympagic organic carbon by the Barents Sea benthos linked to sea ice seasonality
(Peer reviewed; Journal article, 2022)On Arctic shelves, where primary production occurs in both the pelagic and sympagic (ice-associated) habitats, sympagic organic material (OM) can constitute a disproportionate fraction of benthic diets due to higher sinking ... -
Uptake of Ultrashort Chain, Emerging, and Legacy Per- and Polyfluoroalkyl Substances (PFAS) in Edible Mushrooms (Agaricus spp.) Grown in a Polluted Substrate
(Peer reviewed; Journal article, 2023)Uptake of 19 per- and polyfluoroalkyl substances (PFAS), including C3–C14 perfluoroalkyl carboxylic acids (PFCAs), C4, C6, and C8 perfluoroalkyl sulfonates (PFSAs), and four emerging PFAS, was investigated in two mushroom ... -
Use of (Q)SAR genotoxicity predictions and fuzzy multicriteria decision-making for priority ranking of ethoxyquin transformation products
(Peer reviewed; Journal article, 2022)Ethoxyquin (EQ; 6-ethoxy-2,2,4-trimethyl-1,2-dihydroquinoline) has been used as an antioxidant in feed for pets and food-producing animals, including farmed fish such as Atlantic salmon. In Europe, the authorization for ... -
Use of fatty acid profiles to monitor the escapehistory of farmed Atlantic salmon
(Journal article; Peer reviewed, 2015-05-18)Farmed Atlantic salmon can escape from fish farms at various stages of their life, from juveniles to large mature fish. Escapees that enter rivers to spawn pose a threat to the genetic integrity of wild populations. Knowledge ... -
Used vs. new: Does it have consequences for the performance of fishing gear?
(Peer reviewed; Journal article, 2023)Sea trials to test size selectivity equipment in trawls are often limited in time because they are costly, and the results can be influenced by multiple factors that are often overlooked. In the Barents Sea gadoid trawl ... -
Using an omnidirectional video logger to observe the underwater life of marine animals: Humpback whale resting behaviour
(Peer reviewed; Journal article, 2021)Animal-borne video loggers are powerful tools for investigating animal behaviour because they directly record immediate and extended peripheral animal activities; however, typical video loggers capture only a limited area ... -
Using correlative and mechanistic niche models to assess the sensitivity of the Antarctic echinoid Sterechinus neumayeri to climate change
(Peer reviewed; Journal article, 2021)The Southern Ocean is undergoing rapid environmental changes that are likely to have a profound impact on marine life, as organisms are adapted to sub-zero temperatures and display specific adaptations to polar conditions. ... -
Using feedforward neural networks to represent ecosystem dynamics for bioeconomic analysis
(Peer reviewed; Journal article, 2023)We applied feedforward neural networks to represent ecosystem dynamics that are vital to bioeconomic analysis, ecosystem-based management, or what-if analysis regarding the underlying natural resources. Neural networks are ... -
Using multivariate autoregressive state-space models to examine stock structure of Greenland halibut in the North Atlantic
(Peer reviewed; Journal article, 2023)Accurate information on population structure is essential for effective fisheries management. Greenland halibut (Reinhardtius hippoglossoides) in the North Atlantic is managed as four separate offshore stocks. We use ... -
Using natural analogues to investigate the effects of climate change and ocean acidification on Northern ecosystems
(Peer reviewed; Journal article, 2018)Northern oceans are in a state of rapid transition. Still, our knowledge of the likely effects of climate change and ocean acidification on key species in the food web, functionally important habitats and the structure of ... -
Using propagules to restore coastal marine ecosystems

Using Spatial Validity and Uncertainty Metrics to Determine the Relative Suitability of Alternative Suites of Oceanographic Data for Seabed Biotope Prediction. A Case Study from the Barents Sea, Norway
(Peer reviewed; Journal article, 2021)The use of habitat distribution models (HDMs) has become common in benthic habitat mapping for combining limited seabed observations with full-coverage environmental data to produce classified maps showing predicted habitat ... -
Using the best of two worlds: A bio-economic stock assessment (BESA) method using catch and price data
(Others, 2023)Reliable stock assessments are essential for successful and sustainable fisheries management. Advanced stock assessment methods are expensive, as they require age- or length-structured catch and detailed fishery-independent ... -
Using vessel acoustics to detect diving patterns of krill foraging predators automatically: development of a novel method for quantifying impact of krill fishing on seals and penguins
(;WG-EMM-15/25, Research report, 2015-06-20)The aim of this work was to assess the possibilities of automatically generating a dataset of dive behaviour of air-breathing predators, based on acoustic data from a monitoring survey and from commercial krill fishing ... -
Utfordringer som hindrer økt utnyttelse av marine restråstoff og marine arter
(Nofima rapportserie, Research report, 2021)Regjeringen har i flere meldinger uttalt at det skal legges til rette for økt verdiskaping i sjømatnæringen. Et bidrag inn mot dette er utvikling innen sirkulær bioøkonomi og innføring av en mer bærekraftig produksjon og ... -
Utilising IPCC assessments to support the ecosystem approach to fisheries management within a warming Southern Ocean
(Peer reviewed; Journal article, 2021)Southern Ocean marine ecosystems are highly vulnerable to climate-driven change, the impacts of which must be factored into conservation and management. The Commission for the Conservation of Antarctic Marine Living Resources ... -
Utnyttelse av P fra sildeavskjær som alternativ P kilde i fôr til laksesmolt (Salmo salar L.)
(Nofima rapportserie, Research report, 2014)Målet med dette prosjektet var å øke verdiskapningen av marint restråstoff ved å utvikle bioteknologiske løsninger som kan frigjøre P fra fiskebein og gjøre P mer tilgjengelig for laks, samt å utvikle nye marine P ingredienser ... -
