Diel vertical migration and individual behavior of nekton beyond the ocean's twilight zone
(Peer reviewed; Journal article, 2020)Diel vertical migration (DVM) is normally limited to the upper 1000 m. However, the use of ship-borne and stationary submerged echosounders in the Red Sea unveiled consistent formation of daytime patches extending to ... -
Diel vertical movements determine spatial interactions between cod, pelagic fish and krill on an Arctic shelf bank
(Peer reviewed; Journal article, 2020)Predator-prey spatial interactions are essential to understand ecosystem processes like predation rates and trophic interaction strength. In marine systems, such spatial interactions are highly dynamic and difficult to ... -
Diet affects the redox system in developing Atlantic cod(Gadus morhua) larvae
(Journal article; Peer reviewed, 2015-06-12)The growth and development of marine fish larvae fed copepods is superior to those fed rotifers, but the underlying molecular reasons for this are unclear. In the following study we compared the effects of such diets on ... -
Diet analysis of Atlantic salmon (Salmo salar) post-smolts after the ecological regime shift in the Northeast Atlantic
(Peer reviewed; Journal article, 2023)Transition from freshwater to saltwater presents multiple challenges for anadromous Atlantic salmon, and survival during this critical life-stage is thought to influence adult population abundance. Despite this, the role ... -
Diet and life history reduce interspecific and intraspecific competition among three sympatric Arctic cephalopods
(Peer reviewed; Journal article, 2020)Trophic niche and diet comparisons among closely sympatric marine species are important to understand complex food webs, particularly in regions most affected by climate change. Using stable isotope analyses, all ontogenetic ... -
Diet and trophic structure of fishes in the Barents Sea: the Norwegian-Russian program “Year of stomachs” 2015 - establishing a baseline
(Peer reviewed; Journal article, 2020)There is a long history of investigations of fish diet in the Barents Sea. The focus has been on commercially important fish species and their food consumption, while diet and interactions of other fishes have been studied ... -
Diet composition and biomass consumption of harbour seals in Telemark and Aust-Agder, Norwegian Skagerrak
(Peer reviewed; Journal article, 2020)To explore ecosystem dynamics and functions it is vital to obtain knowledge on predator–prey relations. Harbour seals are piscivorous predators that can come into conflict with fisheries. Recently, as the Skagerrak and ... -
The diet of juvenile Atlantic mackerel (Scomber scombrus) feeding in new northern nursery areas along the Norwegian coast
(Peer reviewed; Journal article, 2022)The North-east Atlantic mackerel stock size increased substantially from 2006–2014 coinciding with high recruitment. This resulted in a pronounced northerly geographic expansion of mackerel, followed by an influx of juvenile ... -
Diet quality in the population of Norway and Poland: differences in the availability and consumption of food considering national nutrition guidelines and food market
(Peer reviewed; Journal article, 2021)Adequate nutrition is a public health challenge due to the increase in the incidence of diet-related diseases. The aim of this study was to examine food and nutrient intakes in the light of the current dietary guidelines ... -
Dietary beauvericin and enniatin B exposure cause different adverse health effects in farmed Atlantic salmon
(Peer reviewed; Journal article, 2023)The extensive use of plant ingredients in novel aquafeeds have introduced mycotoxins to the farming of seafood. The emerging enniatin B (ENNB) and beauvericin (BEA) mycotoxins have been found in the novel aquafeeds and ... -
Dietary chlorpyrifos-methyl exposure impair transcription of immune-, detoxification- and redox signaling genes in leukocytes isolated from cod (Gadus morhua)
(Peer reviewed; Journal article, 2022)Inclusion of new environmental toxicants increase with the amount of plant ingredients substituting marine proteins and oils in feed for farmed Atlantic salmon (Salma salar). Agricultural pesticides like chlorpyrifos-methyl, ... -
Dietary choline is related to increased risk of acute myocardial infarction in patients with stable angina pectoris
(Peer reviewed; Journal article, 2019)High plasma choline has been associated with the metabolic syndrome and risk of chronic diseases, including cardiovascular disease. However, dietary choline is not correlated with choline plasma concentrations, and there ... -
Dietary electrolyte balance of Atlantic salmon (Salmo salar) freshwater feeds: Impact on osmoregulation, mineral metabolism and performance in seawater
(Peer reviewed; Journal article, 2022)Dietary electrolyte balance is the equilibrium of monovalent cations and anions that influence the acid-base balance of the feed (dEB = Na + K − Cl, mEq kg−1). Dietary electrolytes/minerals can influence the physiological ... -
Dietary electrolyte imbalance alters drinking rate and gastrointestinal tract water fluxes of Atlantic salmon (Salmo salar) smolt in seawater
(Peer reviewed; Journal article, 2024)It was hypothesized that dietary electrolyte balance (dEB) would influence the dynamics of water, ions, and nutrient fluxes in the gastrointestinal tract (GIT) of Atlantic salmon (Salmo salar) smolts differently depending ... -
Dietary Intake and Biomarkers of Folate and Cobalamin Status in Norwegian Preschool Children: The FINS-KIDS Study
(Peer reviewed; Journal article, 2020)Background: Folate and cobalamin (vitamin B-12) are essential for growth and development. However, few populationbased studies have investigated B-vitamin status in children. Objectives: This study aimed to assess biomarkers ... -
Dietary Klebsormidium sp. Supplementation Improves Growth Performance, Antioxidant and Anti-Inflammatory Status, Metabolism, and Mid-Intestine Morphology of Litopenaeus Vannamei
(Peer reviewed; Journal article, 2022)Filamentous microalga Klebsormidium sp. has huge potential to become a natural and healthy additive in aquatic feed since it contains various bioactive nutrients, such as linoleic acid (LA), carotenoids, and chlorophylls. ... -
Dietary Lipid Modulation of Intestinal Serotonin in Ballan Wrasse (Labrus bergylta)—In Vitro Analyses
(Peer reviewed; Journal article, 2021)Serotonin (5-HT) is pivotal in the complex regulation of gut motility and consequent digestion of nutrients via multiple receptors. We investigated the serotonergic system in an agastric fish species, the ballan wrasse ... -
Dietary micronutrient composition affects fillet texture and muscle cell size in Atlantic salmon (Salmo salar)
(Peer reviewed; Journal article, 2020)During the past 20 years, plant ingredients have taken over as the main constituents in feed for Atlantic salmon. This has changed the nutrient composition of the feeds, the bioavailability of nutrients and perhaps nutrient ... -
