Spawning manipulation, broodfish diet feeding and egg production in farmed Atlantic salmon
(Peer reviewed; Journal article, 2024)Atlantic salmon aquaculture relies on continuous supply of high quality eggs. Broodfish nutrition and manipulation of ovulation time (photoperiod and temperature) are key factors. The optimum feeding period with broodfish ... -
Supplementary materials for Loss of Fshr prevents testicular maturation in Atlantic salmon (Salmo salar L.).
(Others, 2024-01-30)Supplementary materials for "Loss of Fshr prevents testicular maturation in Atlantic salmon (Salmo salar L.)." published in Endocrinology, an Oxford academic journal https://doi.org/10.1210/endocr/bqae013 -
Undersøkelser av hydrokarboner og organiske miljøgifter i sedimenter fra MAREANO-området i 2022
(Rapport fra havforskningen;2023 - 64, Research report, 2023)Havforskningsinstituttet har gjennomført målinger av hydrokarboner (PAH) i sedimenter fra 22 lokaliteter i MAREANO-området, inkludert 14 sedimentkjerner. I overflatesedimenter ble det i tillegg målt totalt hydrokarbon ... -
Poleward spawning of Atlantic mackerel (Scomber scombrus) is facilitated by ocean warming but triggered by energetic constraints
(Peer reviewed; Journal article, 2023)The Northeast Atlantic mackerel is an income breeder with indeterminate fecundity, spawning in multiple batches at optimal temperatures around 11°C in the upper water column during February–July along the continental shelf ... -
PILOT 2023 Rene Vassdrag — Etnevassdraget
(Rapport fra havforskningen, Research report, 2023)PILOT 2023 Rene vassdrag ble utlyst av Handelens Miljøfond i februar 2023. Målet var å rydde ulike vassdrag på vestlandet for søppel før det blir transportert ut i havet. Etnevassdraget var et av de utvalgte vassdragene, ... -

Workshop on seabird bycatch monitoring in the NEAFC regulatory areas (WKBB)
(ICES Scientific Reports, Research report, 2024)In 2021, ICES received a special request for advice from the North-East Atlantic Fisheries Commission (NEAFC) on seabird bycatch in the NEAFC regulatory areas (RAs). Data scoping exercises conducted in 2021, 2022, and 2023 ... -
Recruitment regime shifts and nonstationarity are widespread phenomena in harvestable stocks experiencing pronounced climate fluctuations
(Peer reviewed; Journal article, 2023)Methods to reliably identify jump discontinuities in biological time series and to assess the specific contribution of various covariates are rapidly progressing. Here, we took advantage of these statistical improvements ... -
Large annual variation in the amount of skipped spawning for female Northeast Arctic haddock Melanogrammus aeglefinus
(Peer reviewed; Journal article, 2020)Although the phenomenon of skipped spawning has been described in numerous fishes, time-series are scarce. We used the presence of post-ovulatory follicles in histological gonad slides from females not developing oocytes ... -
Defining sustainable and precautionary harvest rates for data-limited short-lived stocks: a case study of sprat (Sprattus sprattus) in the English Channel
(Peer reviewed; Journal article, 2023)Empirical harvest control rules set catch advice based on observed indicators and are increasingly being used worldwide to manage fish stocks that lack formal assessments of stock and exploitation status. Within the ... -
Size-selective harvesting alters biological traits of marine medaka (Oryzias melastigma)
(Peer reviewed; Journal article, 2023)Under long-term fishing pressure, the biological traits of many wild fish populations have changed. Such phenotypic changes include smaller in size and earlier age-at-maturation, strongly suggesting that fishing could ... -
Occurrence of salmonid alphavirus and piscine orthoreovirus-1 infections in migrating salmon (Salmo salar L.) post-smolt in western Norway
(Peer reviewed; Journal article, 2023)Viral diseases are a serious problem in Atlantic salmon (Salmo salar L.) farming in Norway, often leading to reduced fish welfare and increased mortality. Disease outbreaks in salmon farms may lead to spread of viruses to ... -
Fluoride – a scoping review for Nordic Nutrition Recommendations 2023
(Peer reviewed; Journal article, 2023)Fluoride has a well-documented role in the prevention and treatment of dental caries, but the mechanism is attributed to local effects on the tooth enamel surface rather than systemic effects. Fluoride is not considered ... -
Still Arctic? — The changing Barents Sea
(Peer reviewed; Journal article, 2023)The Barents Sea is one of the Polar regions where current climate and ecosystem change is most pronounced. Here we review the current state of knowledge of the physical, chemical and biological systems in the Barents Sea. ... -
Fine-scale diet data reveals spatial variation in predator-prey interactions in Norwegian fjords
(Dataset, 2024)We explored the diet composition of higher-trophic demersal fish (e.g., Atlantic cod) in three large fjord ecosystems in northern Norway, using spatially and taxonomically highly resolved data and geostatistical modelling. ... -

Impacts of glacial and sea-ice meltwater, primary production and ocean CO2 uptake on ocean acidification state of waters by the 79 North Glacier and northeast Greenland shelf
(Peer reviewed; Journal article, 2023)The waters adjacent to the Nioghalvfjerdsbræ (79 North Glacier, 79NG) are influenced by Greenland Ice Sheet (GrIS) melt, sea-ice meltwater, and waters on the adjacent northeast Greenland shelf (NEGS). We investigated ocean ... -
