Environmental and Genetic (vgll3) Effects on the Prevalence of Male Maturation Phenotypes in Domesticated Atlantic Salmon
(Peer reviewed; Journal article, 2023)Pre-harvest male maturation is problematic for Atlantic salmon (Salmo salar) farmers and is regulated by the environment and genetics (e.g., vgll3). Five families of all-male salmon parr (produced using YY males crossed ... -
Environmental benefits of leaving offshore infrastructure in the ocean
(Peer reviewed; Journal article, 2018)The removal of thousands of structures associated with oil and gas development from the world’s oceans is well underway, yet the environmental impacts of this decommissioning practice remain unknown. Similar impacts will ... -
Environmental change influences the life history of salmon Salmo salar in the North Atlantic Ocean
(Peer reviewed; Journal article, 2016)Annual mean total length (LT) of wild one-sea-winter (1SW) Atlantic salmon Salmo salar of the Norwegian River Imsa decreased from 63 to 54 cm with a corresponding decrease in condition factor (K) for cohorts migrating to ... -
Environmental controls on macrozooplankton and fish distributions over diurnal to seasonal time scales in the northern Barents Sea
(Peer reviewed; Journal article, 2023)We present acoustic observations obtained by bottom mounted echosounders at two locations in the northern Barents Sea and a third on the northern continental slope of the Barents Sea. Data collected over a period of ... -
Environmental drivers of herring growth and how the perception shifts with time series length
(Peer reviewed; Journal article, 2022)Growth is a key component of population dynamics and, thus, fisheries management, yet drivers of its variations are often poorly understood. Using individual data collected over 80 years, we explored how environmental ... -
Environmental drivers of population-level variation in the migratory and diving ontogeny of an Arctic top predator
(Peer reviewed; Journal article, 2022)The development of migratory strategies that enable juveniles to survive to sexual maturity is critical for species that exploit seasonal niches. For animals that forage via breath-hold diving, this requires a combination ... -
Environmental effects of offshore produced water discharges evaluated for the Barents Sea
(NIVA-rapport, Research report, 2019)This report presents (1) an overview of the ecotoxicological knowledge regarding offshore produced water (PW) discharges on the Norwegian Continental Shelf (NCS), (2) an overview of the ecological characteristics and values ... -
Environmental effects of offshore produced water discharges: A review focused on the Norwegian continental shelf
(Peer reviewed; Journal article, 2020)Produced water (PW), a large byproduct of offshore oil and gas extraction, is reinjected to formations or discharged to the sea after treatment. The discharges contain dispersed crude oil, polycyclic aromatic hydrocarbons ... -
Environmental impacts of produced water and drilling waste discharges from the Norwegian offshore petroleum industry
(Peer reviewed; Journal article, 2013)Operational discharges of produced water and drill cuttings from offshore oil and gas platforms are a continuous source of contaminants to continental shelf ecosystems. This paper reviews recent research on the biological ... -
Environmental influences on Norwegian spring-spawning herring (<i>Clupea harengus</i> L.) larvae reveal recent constraints in recruitment success
(Peer reviewed; Journal article, 2020)The lack of any abundant recruiting year class of Norwegian spring-spawning (NSS) herring between 2005 and 2015 contributed to an approximate reduction of 40% in the spawning-stock biomass since 2009, i.e. from 7 to 4 ... -
Environmental stressors may cause unpredicted, notably lagged life-history responses in adults of the planktivorous Atlantic herring
(Peer reviewed; Journal article, 2020)Here we challenge traditional views on the direction of change in teleost body condition and reproductive traits in response to abiotic and biotic factors by studying the data-rich, planktivorous Norwegian spring-spawning ... -
Environmentally realistic concentrations of chlorinated, brominated, and fluorinated persistent organic pollutants induce the unfolded protein response as a shared stress pathway in the liver of Atlantic cod (Gadus morhua)
(Peer reviewed; Journal article, 2023)In the North Sea and North Atlantic coastal areas, fish experience relatively high background levels of persistent organic pollutants. This study aimed to compare the mode of action of environmentally relevant concentrations ... -
Environmentally responsive parasite prevention halves salmon louse burden in commercial marine cages
(Peer reviewed; Journal article, 2023)Though a naturally occurring species throughout the Atlantic, parasitic salmon louse (Lepeophtheirus salmonis) population dynamics are increasingly intertwined with salmonid aquaculture. In contrast to reactive louse ... -
Epidemiological cut-off values for Vibrio anguillarum MIC and disc diffusion data generated by standardised methods
(Peer reviewed; Journal article, 2023)This work aims to generate the data needed to set epidemiological cut-off values for minimum inhibitory concentration (MIC) and disc-diffusion zone measurements of Vibrio anguillarum. A total of 261 unique isolates were ... -
Epifaunal habitat associations on mixed and hard bottom substrates in coastal waters of Northern Norway
(Peer reviewed; Journal article, 2020)Hard and mixed seafloor substrates are an important benthic habitat in coastal northern Norway and they are known to be colonized by relatively diverse communities of sessile epifauna. These assemblages are highly susceptible ... -
Episodic arctic CO2 limitation in the west svalbard shelf
(Journal article; Peer reviewed, 2018)The European Sector of the Arctic Ocean is characterized by low CO2 concentrations in seawater during spring and summer, largely due to strong biological uptake driven by extensive plankton blooms in spring. The spring ... -
Epistatic regulation of growth in Atlantic salmon revealed: a QTL study performed on the domesticated-wild interface
(Peer reviewed; Journal article, 2020)Quantitative traits are typically considered to be under additive genetic control. Although there are indications that non-additive factors have the potential to contribute to trait variation, experimental demonstration ... -
Epithelial Label-Retaining Cells Are Absent during Tooth Cycling in Salmo salar and Polypterus senegalus
(Journal article; Peer reviewed, 2016-04-06)The Atlantic salmon (Salmo salar) and African bichir (Polypterus senegalus) are both actinopterygian fish species that continuously replace their teeth without the involvement of a successional dental lamina. Instead, they ... -
Equipment to tag, track and collect biopsies from whales and dolphins: the ARTS, DFHorten and LKDart systems
(Peer reviewed; Journal article, 2022)Of all animals considered subjects for instrumentation for behavioral or physiological studies, cetaceans probably represent the greatest challenge to the engineer and biologist. The marine environment being harsh to ... -
