The dynamics of 0-group herring Clupea harengus and sprat Sprattus sprattus populations along the Norwegian Skagerrak coast
(Others, 2022)Coastal areas are important habitats for early life stages of many fish species. These habitats are used as nursery grounds and can provide a significant contribution to the recruitment of a fish population. In 1919, ... -
Dynamics of phytoplankton species composition, biomass and nutrients in the North Atlantic during spring and summer - A trans-Atlantic study
(Peer reviewed; Journal article, 2020)During a return trip in May–June 2013 from Bergen, Norway, to Nuuk, Greenland, on the Institute of Marine Research's R/V “G. O. Sars”, four ocean basins, the Norwegian, Iceland, Irminger and Labrador seas, were surveyed ... -
Dynamics of shallow-water juvenile flatfish nursery grounds: application of the self-thinning rule
(Journal article; Peer reviewed, 2007-08-23)Annual development of density and mean weight of juvenile plaice Pleuronectes platessa was examined at 2 nursery grounds (Port Erin Bay, Isle of Man, Irish Sea and Admucknish Bay, Firth of Lorne, west coast of Scotland) ... -
Dynamics of the Norwegian Skagerrak cod: intuition vs inference
(Journal article; Peer reviewed, 2002-10-04) -
Earlier hatching and slower growth, a key to survival in the early life history of Norwegian spring spawning herring
(Journal article; Peer reviewed, 2018)Faster growth in fish larvae is often associated with enhanced survival, and here we investigated whether surviving juvenile Norwegian spring spawning herring Clupea harengus L. generally come from a pool of fast-growing ... -
Earlier or delayed seasonal broodstock spawning changes nutritional status and metabolic programming of growth for next-generation Atlantic salmon
(Peer reviewed; Journal article, 2022)Atlantic salmon (Salmo salar) breeding companies depend on changing light, temperature and feeding regimes to achieve new generations outside the natural spawning season. However, there have been few conducted trials ... -
Earlier sea-ice melt extends the oligotrophic summer period in the Barents Sea with low algal biomass and associated low vertical flux
(Peer reviewed; Journal article, 2023)The decrease in Arctic sea-ice extent and thickness as a result of global warming will impact the timing, duration, magnitude and composition of phytoplankton production with cascading effects on Arctic marine food-webs ... -

Early life growth is affecting timing of spawning in the semelparous Barents Sea capelin (Mallotus villosus)
(Peer reviewed; Journal article, 2021)Capelin (Mallotus villosus) is a forage fish and a key species in the Barents Sea (BS). The BS capelin are semelparous and hence only spawn once along the north coasts of Norway and Russia before they die. The age at ... -
The early marine distribution of Atlantic salmon in the North-east Atlantic: A genetically informed stock-specific synthesis
(Peer reviewed; Journal article, 2021)The survival of Atlantic salmon (Salmo salar), an increasingly rare anadromous species, has declined dramatically during its marine phase, with disproportionate impacts on the poorly understood early post-smolt period. ... -
Early ontogeny of the Atlantic halibut Hippoglossus hippoglossus head
(Journal article; Peer reviewed, 2011-04-04)An ontogenetic sequence of Atlantic halibut Hippoglossus hippoglossus larvae, reared in intensive culture conditions, was cleared and stained and histologically processed to determine normal cranial chondrification for ... -
Early ontogeny of the lesser sandeel (Ammodytes marinus)
(Peer reviewed; Journal article, 2023)Background Lesser sandeel (Ammodytes marinus) is widely distributed in North Sea ecosystems. Sandeel acts as a critical trophic link between zooplankton and top predators (fish, mammals, sea birds). Because they live buried ... -
Early postpartum discharge: maternal depression, breastfeeding habits and different follow-up strategies
(Peer reviewed; Journal article, 2018) -
Early spring subglacial discharge plumes fuel under-ice primary production at a Svalbard tidewater glacier
(Peer reviewed; Journal article, 2021)Subglacial upwelling of nutrient-rich bottom water is known to sustain elevated summer primary production in tidewater-glacier-influenced fjord systems. However, the importance of subglacial upwelling during the early ... -
Eastern boundary circulation and hydrography off Angola building Angolan oceanographic capacities
(Journal article; Peer reviewed, 2018)The eastern boundary region off Angola encompasses a highly productive ecosystem important for the food security of the coastal population. The fish-stock distribution, however, undergoes large variability on intraseasonal, ... -
Echo abundance indices of 0-group fish in the Barents Sea, 1965-1972
(Journal article; Peer reviewed, 1977)In order to obtain estimates of year class strength of 0-group fish, joint international surveys have been conducted each year since 1965 in the Barents Sea. The density of fish has been estimated by visual grading of the ... -
Eco-evolutionary dynamics of Atlantic cod spatial behavior maintained after the implementation of a marine reserve
(Peer reviewed; Journal article, 2022)The effects of marine reserves on the life history and demography of the protected populations are well-established, typically increasing population density and body size. However, little is known about how marine reserves ... -
Ecological adaptation in Atlantic herring is associated with large shifts in allele frequencies at hundreds of loci
(Peer reviewed; Journal article, 2020)Atlantic herring is widespread in North Atlantic and adjacent waters and is one of the most abundant vertebrates on earth. This species is well suited to explore genetic adaptation due to minute genetic differentiation at ... -
Ecological and evolutionary effects of harvesting: lessons from the candy-fish experiment
(Peer reviewed; Journal article, 2013)
