Parameter-sparse modification of Fourier methods to analyse the shape of closed contours with application to otolith outlines
(Journal article; Peer reviewed, 2016-02-05)Elliptical Fourier descriptors (EFDs) have been used extensively in shape analysis of closed contours and have a range of marine applications, such as automatic identification of fish species and discrimination between ... -

Paranucleospora theridion (Microsporidia) infection dynamics in farmed Atlantic salmon Salmo salar put to sea in spring and autumn
(Journal article; Peer reviewed, 2012-10-10)The microsporidian Paranucleospora theridion (syn. Desmozoon lepeophtheirii) is a parasite of Atlantic salmon Salmo salar and also a hyperparasite of the salmon louse Lepeophtheirus salmonis. The parasite develops 2 types ... -
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 ... -
Parasitic nematodes in stomachs of grey seals, Halichoerus grypus, and common seals, Phoca vitulina, along the Norwegian coast.
(ICES CM Documents;1984/N:3, Working paper, 1984)The nematode infestation in stomachs of 55 grey and 127 common seals were examined in the period 1976-1980. The seals were caught in Norwegian coastal waters between 62° and 67° North. In 48 adult grey seals the infestation ... -
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 migration, climate and thermal exposure of larvae: spawning in southern regions gives Northeast Arctic cod a warm start
(Journal article; Peer reviewed, 2011-10-20)Temporal variability in environmental conditions met by early life stages is considered a key driver of fluctuations in recruitment and abundance of fish stocks. Variability in spawning grounds selected by the parental ... -
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 ... -
Passage of infectious pancreatic necrosis virus (IPNV) through invertebrates in an aquatic food chain
(Journal article; Peer reviewed, 1993-06-24)Infectious pancreatic necrosis virus (IPNV) was reisolated from particles containing faeces and pseudofaeces of scallops Pecten maximus after IPNV bath and injection challenges, and from prawns Pandalus borealis and Palaemon ... -

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 ... -
Pathogenicity of nodavirus strains from striped jack Pseudocaranx dentex and Atlantic halibut Hippoglossus hippoglossus, studied by waterborne challenge of yolk-sac larvae of both teleost species
(Journal article; Peer reviewed, 1999-11-30)The present study shows that differences in pathogenicity exist among fish nodavirus strains. In challenge trials, a Japanese strain (SJ93Nag) was highly virulent to larvae of the striped jack Pseudocaranx dentex but ... -
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 ... -
Pathophysiological effect of chronic and acute stress in Atlantic salmon, Salmo salar (Actinopterygii: Salmoniformes: Salmonidae)
(Journal article; Peer reviewed, 2013-12-01)The knowledge on the effect of different stress factors on Atlantic salmon, Salmo salar Linnaeus, 1758, is far from complete and therefore we decided to find out how the low water level stress could effect pathophysiological ... -
Pathways between Primary Production and Fisheries Yields of Large Marine Ecosystems
(Journal article; Peer reviewed, 2012-01-20)The shift in marine resource management from a compartmentalized approach of dealing with resources on a species basis to an approach based on management of spatially defined ecosystems requires an accurate accounting of ... -
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 ... -
