DNA damage and health effects in juvenile haddock (Melanogrammus aeglefinus) exposed to PAHs associated with oil-polluted sediment or produced water
(Peer reviewed; Journal article, 2020)The research objective was to study the presence of DNA damages in haddock exposed to petrogenic or pyrogenic polyaromatic hydrocarbons (PAHs) from different sources: 1) extracts of oil produced water (PW), dominated by ... -
DNA-analysis to monitor fisheries and aquaculture: Too costly?
(Journal article; Peer reviewed, 2018)Evidence from DNA‐analysis is commonplace in human criminal investigations, and while it is increasingly being used in wildlife crime, to date, its application to control and enforcement activities in fisheries and aquaculture ... -
Dnd knockout ablates germ cells and demonstrates germ cell independent sex differentiation in Atlantic salmon
(Journal article; Peer reviewed, 2016-02-18)Introgression of farmed salmon escapees into wild stocks is a major threat to the genetic integrity of wild populations. Using germ cell-free fish in aquaculture may mitigate this problem. Our study investigated whether ... -
Do background levels of the pesticide pirimiphosmethyl in plant-based aquafeeds affect food safety of farmed Atlantic salmon?
(Peer reviewed; Journal article, 2020)The substitution of fish oil and fishmeal with plant-based ingredients in commercial aquafeeds for Atlantic salmon, may introduce novel contaminants that have not previously been associated with farmed fish. The organophosphate ... -
Do eggs collected in egg surveys accurately reflect adult fecundities?
(Conference object, 2014) -
Does density influence relative growth performance of farm, wild and F1 hybrid Atlantic salmon in semi-natural and hatchery common garden conditions?
(Journal article; Peer reviewed, 2016-07-06)The conditions encountered by Atlantic salmon, Salmo salar L., in aquaculture are markedly different from the natural environment. Typically, farmed salmon experience much higher densities than wild individuals, and may ... -
Does grab size influence sampled macrofauna composition? A test conducted on deep-sea communities in the northeast Atlantic
(Journal article; Peer reviewed, 2019)In deep-sea surveys, heavy gears are often preferred to effectively collect macro benthos while smaller samplers are sufficient in coastal and shallow areas. However, there are few comparative studies of the samples retained ... -
Does seismic have an effect on zooplankton? - Field study at Ekofisk with RV Kristine Bonnevie
(Toktrapport;2022 - 9, Research report, 2022)Toktnr: 2022611 -
Does the thermal component of warm water treatment inflict acute lesions on Atlantic salmon (Salmo salar)?
(Peer reviewed; Journal article, 2020)Warm water treatment, i.e. exposure to sea water at a temperature of 28–34 °C for 20–30 s, has in recent years been widely used for delousing of Atlantic salmon (Salmo salar) and rainbow trout (Oncorhynchus mykiss) in ... -
Domestication leads to increased predation susceptibilit
(Journal article; Peer reviewed, 2020)Domestication involves adapting animals to the human-controlled environment. Genetic changes occurring during the domestication process may manifest themselves in phenotypes that render domesticated animals maladaptive for ... -
Domestication-induced reduction in eye size revealed in multiple common garden experiments: The case of Atlantic salmon (Salmo salar L.)
(Peer reviewed; Journal article, 2021)Domestication leads to changes in traits that are under directional selection in breeding programmes, though unintentional changes in nonproduction traits can also arise. In offspring of escaping fish and any hybrid progeny, ... -
Don't mind if I do: Arctic humpback whales respond to winter foraging opportunities before migration
(Peer reviewed; Journal article, 2023)Migration patterns are fundamentally linked to the spatio-temporal distributions of prey. How migrating animals can respond to changes in their prey's distribution and abundance remains largely unclear. During the last ... -
‘Double trouble’: the expansion of the Suez Canal and marine bioinvasions in the Mediterranean Sea
(Journal article; Peer reviewed, 2014-09-28) -
Drift diving: A quick and accurate method for assessment of anadromous salmonid spawning populations
(Peer reviewed; Journal article, 2021)The accuracy of drift diving surveys of Atlantic salmon, Salmo salar L. and sea trout, Salmo trutta L., was evaluated by comparing the abundance and size distribution with catches in a fish trap over 6 years in the River ... -
Drift indices confirm that rapid larval displacement is essential for recruitment success in high-latitude oceans
(Peer reviewed; Journal article, 2021)Larval drift is a key process for successful fish recruitment. We used Norwegian spring-spawning herring (Clupea harengus) as model species to investigate the relationship between larval drift and recruitment. Larval drift ... -
Drivers of change in Arctic fjord socio-ecological systems: Examples from the European Arctic
(Peer reviewed; Journal article, 2023)Fjord systems are transition zones between land and sea, resulting in complex and dynamic environments. They are of particular interest in the Arctic as they harbour ecosystems inhabited by a rich range of species and ... -
Drivers of Interannual Sea Ice Concentration Variability in the Atlantic Water Inflow Region North of Svalbard
(Peer reviewed; Journal article, 2021)Sea ice concentration along the continental margin of the Arctic Ocean is influenced by a multitude of factors, including local freezing and melting due to atmospheric forcing, lateral advection of sea ice by winds and ... -
Drivers of the summer-distribution of Northeast Atlantic mackerel (Scomber scombrus) in the Nordic Seas from 2011 to 2017; a Bayesian hierarchical modelling approach.
(Journal article; Peer reviewed, 2019)Identifying factors that are statistically correlated with the geographical distribution dynamics of a species can facilitate our understanding of causal physiological and ecological relationships. Northeast Atlantic (NEA) ... -
Dual-Organ Transcriptomic Analysis of Rainbow Trout Infected With Ichthyophthirius multifiliis Through Co-Expression and Machine Learning
(Peer reviewed; Journal article, 2021)Ichthyophthirius multifiliis is a major pathogen that causes a high mortality rate in trout farms. However, systemic responses to the pathogen and its interactions with multiple organs during the course of infection have ... -
A Dynamic Occupancy Model for Interacting Species with Two Spatial Scales
(Peer reviewed; Journal article, 2023)Occupancy models have been extended to account for either multiple spatial scales or species interactions in a dynamic setting. However, as interacting species (e.g., predators and prey) often operate at different spatial ...
