Diversity and seasonal development of large zooplankton along physical gradients in the Arctic Barents Sea
(Peer reviewed; Journal article, 2023)Due to ongoing climate change, a new Arctic Ocean ecosystem is emerging. Within the framework of the Nansen Legacy project, we investigated the community composition of the large zooplankton and its seasonal development ... -
Diversity, distribution patterns and indicatory potential of echinoderm communities of the tropical East Atlantic (Gulf of Guinea): Influence of multiple natural and anthropogenic factors along a 25–1000 m depth gradient
(Peer reviewed; Journal article, 2023)All earlier studies of the West African echinoderm fauna have focused on taxonomy, and general knowledge about benthic community responses to various human related threats are poorly diagnosed and not monitored along the ... -
Diversity, habitat endemicity and trophic ecology of the fauna of Loki’s Castle vent field on the Arctic Mid-Ocean Ridge
(Peer reviewed; Journal article, 2024)Loki’s Castle Vent Field (LCVF, 2300 m) was discovered in 2008 and represents the first black-smoker vent field discovered on the Arctic Mid-Ocean Ridge (AMOR). However, a comprehensive faunal inventory of the LCVF has not ... -
DNA and scale reading to identify repeat spawning in Atlantic salmon: Unique insights into patterns of iteroparity
(Peer reviewed; Journal article, 2023)Iteroparity represents an important but often overlooked component of life history in anadromous Atlantic salmon. Here, we combined individual DNA profiling and scale reading to identify repeat spawners among ~8000 adult ... -
DNA barcoding confirms the first record of a Desmodema polystictum (Ogilby, 1898) egg and all-time high adult catches in the Indian Ocean.
(Peer reviewed; Journal article, 2019)The eggs of Polka-dot ribbonfish Desmodema polystictum have been recorded for the first time in the Indian Ocean. Although the only previous information on eggs from this species consists of line drawings from 1973 (Pacific ... -
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 processing of black soldier fly larvae meal affect the amino acid solubility in Atlantic salmon (Salmo salar)?
(Peer reviewed; Journal article, 2024)The present work aimed to evaluate protein and amino acid (AA) digestibility/solubility of different black soldier fly larvae (BSFL) based meals for Atlantic salmon in vivo and in vitro. Three types of insect meals that ... -
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 ... -
