Differences in growth and survival between cod Gadus morhua and herring Clupea harengus early stages co-reared at variable prey concentrations
(Journal article; Peer reviewed, 2015-09-28)It was hypothesized that the survival and growth strategies of herring Clupea harengus, displaying a flexible reproductive activity, are adapted to coping with longer periods of prey deprivation (i.e. more variable prey ... -
Differences in metabolic rate between two Atlantic cod (Gadus morhua) populations estimated with carbon isotopic composition in otoliths
(Peer reviewed; Journal article, 2021)The isotopic composition of inorganic carbon in otoliths (δ13Coto) can be a useful tracer of metabolic rates and a method to study ecophysiology in wild fish. We evaluated environmental and physiological sources of δ13Coto ... -
Differences in nutrient and undesirable substance concentrations in Maurolicus muelleri across the Bay of Biscay, Norwegian fjords, and the North Sea
(Peer reviewed; Journal article, 2023)We are having pressing issues of global food insecurity and malnutrition. Mesopelagic communities in the North Atlantic have been estimated to have high biomasses of organisms. Some of these low-trophic organisms are known ... -
Different Dietary Levels of Protein to Lipid Ratio Affected Digestive Efficiency, Skeletal Growth, and Muscle Protein in Rainbow Trout Families
(Journal article; Peer reviewed, 2009)Normal Protein (NP) and High Protein (HP) diets were provided to rainbow trout families from juvenile to maturity. Muscle protein concentration increased during growth and the protein to lipid (P/L) ratio was doubled at ... -
Differential action of androgen implants on the spermatogenesis of pre-pubertal sea bass exposed to a continuous light regime
(Peer reviewed; Journal article, 2021)This study investigated the influence of long-term T and 11-KT administration (by means of an implant) on the synthesis and release of gonadotropins (Fsh, Lh) and spermatogenesis progression in juvenile male sea bass exposed ... -
Differential changes in growth patterns of anadromous brown trout and Atlantic salmon from the River Etneelva over a 25-year period
(Journal article; Peer reviewed, 2013-10-15)Freshwater and marine growth of anadromous brown trout (Salmo trutta) and Atlantic salmon (Salmo salar) from the River Etneelva was analysed in relation to river, fjord and ocean temperatures during the periods 1976-1982 ... -
Differential developmental toxicity of crude oil in early life stages of Atlantic halibut (Hippoglossus hippoglossus)
(Peer reviewed; Journal article, 2021)To further understand the complexity of developmental toxicity of dispersed oil and importance of exposure timing on fish early life stages, Atlantic halibut (Hippoglossus hippoglossus) were exposed to environmentally ... -
Differential effects of internal tagging depending on depth treatment in Atlantic salmon: a cautionary tale for aquatic animal tag use.
(Journal article; Peer reviewed, 2019)Electronic tags are widespread tools for studying aquatic animal behavior; however, tags risk behavioral manipulation and negative welfare outcomes. During an experiment to test behavioral differences of Atlantic salmon ... -
Differential processing of yolk proteins during oocyte hydration in marine fishes (Labridae) that spawn benthic and pelagic eggs
(Journal article; Peer reviewed, 2002-07-18)The yolk proteins and free amino acids (FAA) were investigated during oocyte maturation in 4 species of Labridae with either benthic or pelagic eggs. Benthic eggs and oocytes of both types had a small FAA pool dominated ... -
Differential production of prostaglandins and prostacyclins by liver and head kidney cells from Atlantic salmon challenged with arachidonic and eicosapentaenoic acids
(Peer reviewed; Journal article, 2021)Polyunsaturated fatty acids such as arachidonic and eicosapentaenoic acids are the precursors of eicosanoid metabolites (e.g prostaglandins and prostacyclins) which regulate inflammatory and immune response processes in ... -
Differential reproductive plasticity under thermal variability in a freshwater fish (Danio rerio)
(Peer reviewed; Journal article, 2022)Human-driven increases in global mean temperatures are associated with concomitant increases in thermal variability. Yet, few studies have explored the impacts of thermal variability on fitness-related traits, limiting our ... -
Differential responses of three sympatric seabirds to spatio-temporal variability in shared resources
(Journal article; Peer reviewed, 2012-11-14)Environmental change linked to climate and human activities may affect top predators via the food chain in marine systems. Understanding the functional link between resources and predator responses (e.g. foraging effort, ... -
Diffusive and advective cross-frontal fluxes of inorganic nutrients and dissolved inorganic carbon in the Barents Sea in autumn
(Peer reviewed; Journal article, 2023)The Atlantic Water, entering the Arctic through the Barents Sea and Fram Strait, is the main source of nutrients in the Arctic Ocean. The Barents Sea is divided by the Polar Front into an Atlantic-dominated domain in the ... -
Digital Data Help Explain Drivers of Angler Satisfaction: An Example from Southern Norway
(Peer reviewed; Journal article, 2022)We analyzed trip-level self-reports collected by a cell phone app to understand angler satisfaction of fishing for sea trout Salmo trutta (anadromous Brown Trout) in southern Norway. We found no clear support for a positive ... -

Digital fisheries data in the Internet age: Emerging tools for research and monitoring using online data in recreational fisheries
(Peer reviewed; Journal article, 2022)Recreational fisheries are diverse in scale, scope, and participation worldwide, constituting an important ecosystem service of marine and freshwater ecosystems. Management of these socio-ecological systems is challenged ... -
Direct and indirect climate forcing in a multi-species marine system
(Journal article; Peer reviewed, 2010-10)Interactions within and between species complicate quantification of climate effects, by causing indirect, often delayed, effects of climate fluctuations and compensation of mortality. Here we identify direct and indirect ... -
Direct and indirect effects of sea ice cover on major zooplankton groups and planktivorous fishes in the Barents Sea
(Peer reviewed; Journal article, 2019)Reductions in Arctic sea ice affect marine food webs through a multitude of direct and indirect effects. We here analysed direct, indirect, and delayed associations between winter sea ice cover and year-to-year changes in ... -
Direct evidence of increased natural mortality of a wild fish caused by parasite spillback from domestic conspecifics
