Parasite development affect dispersal dynamics; infectivity, activity and energetic status in cohorts of salmon louse copepodids
(Peer reviewed; Journal article, 2020)The salmon louse, Lepeophtheirus salmonis, is a parasitic copepod infecting wild and farmed salmonid fishes in the northern hemisphere. It has a direct lifecycle with a planktonic dispersal phase and an infective copepodid ... -
Parasite management in aquaculture exerts selection on salmon louse behaviour
(Peer reviewed; Journal article, 2021)The evolution of pest resistance to management strategies is a major challenge for farmed systems. Mitigating the effects of pest adaptation requires identifying the selective pressures imposed by these strategies. In ... -
Parental high dietary arachidonic acid levels modulated the hepatic transcriptome of adult zebrafish (Danio rerio) progeny
(Journal article; Peer reviewed, 2018)Disproportionate high intake of n-6 polyunsaturated fatty acids (PUFAs) in the diet is considered as a major human health concern. The present study examines changes in the hepatic gene expression pattern of adult male ... -
Parental micronutrient deficiency distorts liver DNA methylation and expression of lipid genes associated with a fatty-liver-like phenotype in offspring
(Journal article; Peer reviewed, 2018)Micronutrient status of parents can affect long term health of their progeny. Around 2 billion humans are affected by chronic micronutrient deficiency. In this study we use zebrafish as a model system to examine morphological, ... -
Parental selenium nutrition affects the one-carbon metabolism and the hepatic dna methylation pattern of rainbow trout (Oncorhynchus mykiss) in the progeny
(Peer reviewed; Journal article, 2020)Selenium is an essential micronutrient and its metabolism is closely linked to the methionine cycle and transsulfuration pathway. The present study evaluated the effect of two different selenium supplements in the diet of ... -
Particle aggregation at the edges of anticyclonic eddies and implications for distribution of biomass
(Journal article; Peer reviewed, 2012)Acoustic measurements show that the biomass of zooplankton and mesopelagic fish is redistributed by mesoscale variability and that the signal extends over several hundred meters depth. The mechanisms governing this ... -

Pasteurella spp. Infections in Atlantic salmon and lumpsucker
(Peer reviewed; Journal article, 2021)The use of cleaner fish as a delousing method in Norwegian salmonid aquaculture has increased tremendously over the last few years. This has led to the emergence of a new large industry of farming lumpsuckers (Cyclopterus ... -
Pathological findings in bycaught harbour porpoises (Phocoena phocoena) from the coast of Northern Norway
(Peer reviewed; Journal article, 2021)Due to little prior knowledge, the present study aims to investigate the health status of bycaught harbour porpoises from the northernmost Arctic Norwegian coastline. Gross, histopathological and parasitological investigations ... -
Patterns and drivers of megabenthic secondary production on the Barents Sea shelf
(Journal article; Peer reviewed, 2016-03-21)Megabenthos plays a major role in the overall energy flow on Arctic shelves, but information on megabenthic secondary production on large spatial scales is scarce. Here, we estimated for the first time megabenthic secondary ... -
Patterns, efficiency and ecosystem effects when fishing Calanus finmarchicus in the Norwegian Sea—using an individual-based model
(Peer reviewed; Journal article, 2021)Due to the important role of Calanus finmarchicus as key prey for the abundant pelagic fish stocks (Northeast Atlantic mackerel, Norwegian spring spawning herring, blue whiting) in the Norwegian Sea, an increase in the ... -
Påvirkning fra lakselus på vill laksefisk - ROC
(Rapport fra havforskningen;2020 - 55, Research report, 2020)Vi har utviklet en metode som oversetter luselarver i vannmassene til lus per fisk i smoltbur. Resultatene presenteres som horisontale kart i tre kategorier og tidsserier. Resultatene fra ROC-metoden kan lettest tolkes som ... -
Påvirkning fra lakselus på vill laksefisk - ROC, estimert fra luselarvefelt med stor variabilitet
(Rapport fra havforskningen;2019 - 52, Research report, 2019)For å beregne hvor i fjordene og langs kysten der er så mye lakselus i vannmassene at det vil gjøre skalde på ville laksefisker som svømmer gjennom eller oppholder seg i området har vi utviklet en metode som regner om fra ... -
Pelagic ecosystem characteristics across the atlantic water boundary current from Rijpfjorden, Svalbard, to the Arctic ocean during summer (2010-2014)
(Journal article; Peer reviewed, 2019)The northern coast of Svalbard contains high-arctic fjords, such as Rijpfjorden (80°N 22°30′E). This area has experienced higher sea and air temperatures and less sea ice in recent years, and models predict increasing ... -
Pelagic ecosystem dynamics between late autumn and the post spring bloom in a sub-Arctic fjord
(Peer reviewed; Journal article, 2022)Marine ecosystems, and particularly fjords, are experiencing an increasing level of human activity on a year-round basis, including the poorly studied winter period. To improve the knowledge base for environmentally ... -
Pelagic occurrences of the ice amphipod Apherusa glacialis throughout the Arctic
(Others, 2020)Apherusa glacialis is a common, sea ice-associated amphipod found throughout the Arctic Ocean and has long been considered permanently associated with the sea ice habitat. However, pelagic occurrences of A. glacialis have ... -
