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 ... -
Past and Future Grand Challenges in Marine Ecosystem Ecology

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 ... -
Patterns of Ichthyobodo necator sensu stricto infections on hatchery-reared Atlantic salmon Salmo salar in Norway
(Journal article; Peer reviewed, 2010-02-17)Infection patterns with ectoparasitic flagellates belonging to the genus Ichthyobodo were studied in an Atlantic salmon Salmo salar (L.) hatchery in western Norway during an 11 mo period, from eyed eggs to smoltification. ... -
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 ... -
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 Fish Behaviour During Trawl Sampling Off Angola
(Journal article; Peer reviewed, 2011-12-16)Large sardinella (Sardinella maderensis and Sardinella aurita) in warm waters off the coast of Africa are known to be a challenge for pelagic trawl sampling, for example during acoustic surveys for abundance estimation. ... -
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 ... -
