Population structure discovered in juveniles of Greenland halibut (Reinhardtius hippoglossoides Walbaum, 1792)
(Peer reviewed; Journal article, 2023)Understanding the genetic differentiation among populations of most marine fish requires investigating the differences among spawning grounds. However, this can be challenging as spawning grounds for some species are not ... -
Population structure in Atlantic cod in the eastern North Sea-Skagerrak-Kattegat: early life stage dispersal and adult migration
(Journal article; Peer reviewed, 2016-02-03) -
Population structure of Ammodytes marinus in the Northeast Atlantic
(ICES CM Documents;1996/G:23, Working paper, 1996)Samples of the lesser sandeel species Ammodytes marinus Raitt were collected from Iceland, Denmark, Scotland, the Faeroe Islands and central and northern North Sea, and analysed for frequency distributions of genotypes ... -
Population structure of bycaught harbour porpoise (Phocoena phocoena) in Norway

Population structure of European sprat (Sprattus sprattus) in the Greater North Sea ecoregion revealed by otolith shape analysis
(Peer reviewed; Journal article, 2021)A successful discrimination of fish populations is essential for sustainable management and assessment. Otolith shape analysis has been used on several species to reveal their population structure. Our aim was to use the ... -
Population structure of Sebastes mentella in the North-East Arctic

Populations of the deep-sea shrimp (Pandalus borealis Krøyer) in the Barents Sea
(Fiskeridirektoratets skrifter, Serie Havundersøkelser, Research report, 1983)Three populations of P. borealis were identified in the open part of the Barents Sea. In the (4-1) population the females spawn each year and sex-change occurs 4 years old. This population was found in the soutwestern ... -

Position prediction of herring schools in purse-seine capture situations
(ICES CM Documents;1987/B:10, Working paper, 1987)Sonar observations of herring schools in the North Sea and along the Norwegian Coast reveal a rather constant swimming behaviour of individual schools in purse-seine capture situations. On the basis of this a method for ... -
Positive and negative feedbacks related to the Arctic Oscillation revealed by air-sea heat fluxes
(Journal article; Peer reviewed, 2019)The NCEP reanalysis data of surface heat fluxes and other related data are used to study their relationship with the Arctic Oscillation (AO). Positive and negative high correlation regions (HCR) between heat fluxes and the ... -
Positive relationships between bottom trawl and acoustic data
(ICES CM documents, Working paper, 2004)Demersal fish stock biomass is usually estimated using commercial landings data, ‘tuned’ by various types of survey data, usually trawl. When collecting fish data by trawl it is only possible to take relatively small numbers ... -
A positive temperature-dependent effect of elevated CO<inf>2</inf> on growth and lipid accumulation in the planktonic copepod, Calanus finmarchicus
(Peer reviewed; Journal article, 2022)Calanus finmarchicus were reared from eggs to adults at 12°C and 16°C with non-limiting food in combination with ambient (600 μatm) and high (1100 μatm) pCO2. These conditions are likely to be encountered by the species ... -
Possibilities and limitations of extensive aquaculture of marine fish: evaluation of current results with Atlantic cod and further prospects
(ICES CM documents, Working paper, 1998) -
Possible adverse impact of contaminants on Atlantic cod population dynamics in coastal ecosystems
(Journal article; Peer reviewed, 2019)While many in-laboratory ecotoxicological studies have shown the adverse impact of pollutants to the fitness of an individual, direct evidence from the field on the population dynamics of wildlife animals has been lacking. ... -
Possible future scenarios for two major Arctic Gateways connecting Subarctic and Arctic marine systems: I. Climate and physical-chemical oceanography
(Peer reviewed; Journal article, 2021)We review recent trends and projected future physical and chemical changes under climate change in transition zones between Arctic and Subarctic regions with a focus on the two major inflow gateways to the Arctic, one in ... -
Possible influence of salmon farming on long-term resident behaviour of wild saithe (Pollachius virens L.)
(Journal article; Peer reviewed, 2014-06-13)The culture of Atlantic salmon is one of the most developed aquaculture industries in the world. The production from smolt to market size usually takes place in sea cages in open waters, and these structures tend to attract ... -

Post-release effects of catch and release angling for sea trout: Mortality, growth and wound healing
(Peer reviewed; Journal article, 2023)Sea trout (anadromous brown trout, Salmo trutta L.) is a popular recreational angling target species in the Baltic Sea region and beyond. Across countries, a substantial part of angled sea trout is released after capture ... -
Postglacial species arrival and diversity buildup of northern ecosystems took millennia
(Peer reviewed; Journal article, 2022)What drives ecosystem buildup, diversity, and stability? We assess species arrival and ecosystem changes across 16 millennia by combining regional-scale plant sedimentary ancient DNA from Fennoscandia with near-complete ...
