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 ... -
Erfaringer og analyser fra drift av oppdrettsanlegg på eksponerte lokaliteter
(Research report, 2012)Dette forprosjektet har hatt som mål å legge til rette for videreutvikling av forskningsrelaterte problemstillinger innen tema drift av eksponerte oppdrettslokaliteter. Eksponerte lokaliteter er her derfor å forstå som ... -
Ernæringsbehov og fôring for optimal helse og overlevelse av rensefisk - Del 1 berggylt
(Nofima rapportserie, Research report, 2021)Berggylt bør i alle livsstadier tilbys fôr som er prosessert ved lave temperaturer, som agglomerering eller kaldekstrudering, fordi dette gir bedre mineralisering og mindre deformiteter, og også redusert dødelighet hos ... -
Ernæringsbehov og fôring for optimal helse og overlevelse av rensefisk - Del 2 Rognkjeks
(Nofima rapportserie, Research report, 2021)Rognkjeks har et velutviklet tarmsystem, men pH i magen faller først ved 1,0-1,5 gram. Rognkjeksen bør derfor tilbys agglomerert eller kaldekstrudert fôr fram til denne størrelsen. Fôr med 55 % protein, 17 % fett og 6 % ... -
Erucic acid (22:1n-9) in fish feed, farmed, and wild fish and seafood products
(Journal article; Peer reviewed, 2018)The European Food Safety Authority (EFSA) published a risk assessment of erucic acid (22:1n-9) in 2016, establishing a Tolerable Daily Intake (TDI) for humans of 7 mg kg−1 body weight per day. This report largely excluded ... -
Escape of hake (Merluccius merluccius), horse mackerel (Trachurus trachurus) and blue whiting (Micromesistius poutassou) in codends with shortened lastridge ropes
(Peer reviewed; Journal article, 2022)Diamond meshes in trawl codends have limited openness, which reduces escape opportunities for roundfish. Shortening the lastridge ropes (LR) attached to codend selvedges can increase the availability of open meshes resulting ... -
Escape Survival and Scale Damage Assessment of Red Mullet (Mullus barbatus Linnaeus, 1758) during Bottom Trawling in the Central Mediterranean Sea
(Peer reviewed; Journal article, 2023)Fisheries are amongst the most important anthropogenic activities that strongly impact the marine environment. Therefore, stock assessments are routinely carried out to evaluate the status of the main commercial species ... -
Essay om fiskerier i Porsangerfjorden før og nå - et resultat av møter mellom fjordbrukere og forskere
(Rapport fra havforskningen;2020 - 41, Research report, 2020)Porsangerfjorden gikk fra å være en fiskerik fjord i første halvdelen av 1900-tallet, til en mye mer fiskefattig fjord i den andre halvdelen. Den fiskefattige tilstanden har vedvart fram til i dag. Den invaderende kongekrabben ... -
Establishing the Foundation for the Global Observing System for Marine Life
(Peer reviewed; Journal article, 2021)Maintaining healthy, productive ecosystems in the face of pervasive and accelerating human impacts including climate change requires globally coordinated and sustained observations of marine biodiversity. Global coordination ... -
Estimated abundances of cetacean species in the Northeast Atlantic from Norwegian shipboard surveys conducted in 2014-2018
(Peer reviewed; Journal article, 2020)A ship-based mosaic survey of Northeast Atlantic cetaceans was conducted over a 5-year period between 2014–2018. The area surveyed extends from the North Sea in the south (southern boundary at 53oN), to the ice edge of the ... -
