Common trends in recruitment dynamics of north-east Atlantic fish stocks and their links to environment, ecology and management
(Journal article; Peer reviewed, 2019)Recruitment dynamics are challenging to assess or predict because of the many underlying drivers that vary in their relevance over time and space. Stock size, demographic and trait composition, condition and distribution ... -
Insect-based diets high in lauric acid reduce liver lipids in freshwater Atlantic salmon
(Journal article; Peer reviewed, 2018)We evaluated the effect of a diet containing insect meal and insect oil on nutrient utilization, tissue fatty acid profile and lipid metabolism of freshwater Atlantic salmon (Salmo salar). Insect meal and insect oil from ... -
DNA-analysis to monitor fisheries and aquaculture: Too costly?
(Journal article; Peer reviewed, 2018)Evidence from DNA‐analysis is commonplace in human criminal investigations, and while it is increasingly being used in wildlife crime, to date, its application to control and enforcement activities in fisheries and aquaculture ... -
Spatiotemporal variability of barium in arctic sea-ice and seawater
(Journal article; Peer reviewed, 2018)Freshwater export from the Arctic is critical in determining the density of water at sites of North Atlantic deep water formation, which in turn influences the global flux of oceanic heat and nutrients. We need geochemical ... -
Spatial and temporal variations in seabird bycatch: Incidental bycatch in the Norwegian coastal gillnet-fishery
(Peer reviewed; Journal article, 2019)The general decline of seabird populations worldwide raises large concerns. Although multiple factors are interacting to cause the observed trends, increased mortality from incidental bycatch in fisheries has proven to be ... -
Family differences on triploid induction, sexual maturation and its contribution to sea cage performance of Atlantic cod, Gadus morhua
(Journal article; Peer reviewed, 2019)Early maturation has been one of the biological bottlenecks of commercializing Atlantic cod culture. To overcome the bottleneck, production of sterile fish through triploidy and other molecular techniques have been suggested ... -
The metagenome of the female upper reproductive tract
(Peer reviewed; Journal article, 2018) -
Implications for introgression: Has selection for fast growth altered the size threshold for precocious male maturation in domesticated Atlantic salmon?
(Peer reviewed; Journal article, 2018) -
Local cod (Gadus morhua) revealed by egg surveys and population genetic analysis after longstanding depletion on the Swedish Skagerrak coast
(Journal article; Peer reviewed, 2018)Dramatic and persistent reductions in Atlantic cod (Gadus morhua) are common in many coastal areas. While offshore cod stocks still were abundant and productive, the Swedish west coast showed signs of diminishing adult cod ... -
Oil from transgenic Camelina sativa containing over 25 % n-3 long-chain PUFA as the major lipid source in feed for Atlantic salmon (Salmo salar)
(Journal article; Peer reviewed, 2018)Facing a bottleneck in the growth of aquaculture, and a gap in the supply and demand of the highly beneficial n-3 long-chain PUFA (LC-PUFA), sustainable alternatives to traditional marine-based feeds are required. Therefore, ... -
Functional roles and redundancy of demersal Barents Sea fish: Ecological implications of environmental change
(Journal article; Peer reviewed, 2018)When facing environmental change and intensified anthropogenic impact on marine ecosystems, extensive knowledge of how these systems are functioning is required in order to manage them properly. However, in high-latitude ... -
Fangstkontroll i kolmuletrål - Forstudie — Fiskeforsøk på Porcupinebanken i 2018
(Rapport fra havforskningen;, Research report, 2019)Under FHF Prosjekt 901495: Fangstkontroll i kolmuletrål – Forstudie ble det samlet inn systematiske data om de mulige årsakene til og løsninger på sporadisk sprenging av sekker i det kommersielle trålfiskeriet etter kolmule ... -
Early postpartum discharge: maternal depression, breastfeeding habits and different follow-up strategies
(Peer reviewed; Journal article, 2018) -
Marine naturverdier i Telemark – status, trusler og muligheter. Innspill til kystsoneplan for Telemark.
(NIVA-rapport, Research report, 2018)Denne rapporten er skrevet på oppdrag for Telemark fylkeskommune. Rapporten gir en kunnskapsstatus over forekomst og utbredelse av marine naturverdier, deres tilstand og hvilke kjente trusler disse er utsatt for med hensyn ... -
Omega-3 and alpha-tocopherol provide more protection against contaminants in novel feeds for Atlantic salmon (Salmo salar L.) than omega-6 and gamma tocopherol
(Peer reviewed; Journal article, 2016)Extended use of plant ingredients in Atlantic salmon farming has increased the need for knowledge on the effects of new nutrients and contaminants in plant based feeds on fish health and nutrient-contaminant interactions. ... -
Mortality and reduced photosynthetic performance in sugar kelp Saccharina latissima caused by the salmon-lice therapeutant hydrogen peroxide
(Journal article; Peer reviewed, 2019)Sugar kelp Saccharina latissima is one of the dominating kelp species on sheltered sublittoral sites along the Norwegian coastline, providing important habitats and ecosystem services. In finfish aquaculture in Norway, ... -
The role of dietary methionine concentrations on growth, metabolism and N-retention in cobia (Rachycentron canadum) at elevated water temperatures
(Journal article; Peer reviewed, 2018)This study determined impacts of dietary methionine concentrations at two temperatures on growth, feeding efficiency and N‐metabolites in juvenile cobia. Methionine concentrations of the experimental diets were deficient ... -
Broad-scale distribution of the winter protozooplankton community in the North Sea.
(Peer reviewed; Journal article, 2018)Protozooplankton (PZP) (here size range: 12–200 μm) are rarely sampled over a broad scale, especially in ecosystem monitoring programs, despite their trophodynamic importance as grazers in the microbial loop and as prey ... -
Potential of a no‐take marine reserve to protect home ranges of anadromous brown trout (Salmo trutta)
(Journal article; Peer reviewed, 2018)The extent to which no‐take marine reserves can benefit anadromous species requires examination. Here, we used acoustic telemetry to investigate the spatial behavior of anadromous brown trout (sea trout, Salmo trutta) in ... -
Combined effects of fishing and oil spills on marine fish: Role of stock demographic structure for offspring overlap with oil
(Journal article; Peer reviewed, 2018)It has been proposed that the multiple pressures of fishing and petroleum activities impact fish stocks in synergy, as fishing-induced demographic changes in a stock may lead to increased sensitivity to detrimental effects ...
