The exorhodopsin and melanopsin systems in the pineal complex and brain at early developmental stages of Atlantic halibut (Hippoglossus hippoglossus)
(Peer reviewed; Journal article, 2014)The complexity of the nonvisual photoreception systems in teleosts has just started to be appreciated, with colocalization of multiple photoreceptor types with unresolved functions. Here we describe an intricate expression ... -
An Expanded Gene Catalog of Mouse Gut Metagenomes
(Peer reviewed; Journal article, 2021)High-quality and comprehensive reference gene catalogs are essential for metagenomic research. The rather low diversity of samples used to construct existing catalogs of the mouse gut metagenome limits the numbers of ... -
Expected Climate Change in the High Arctic—Good or Bad for Arctic Charr?
(Peer reviewed; Journal article, 2023)Lakes in the High Arctic are characterized by their low water temperature, long-term ice cover, low levels of nutrients, and low biodiversity. These conditions mean that minor climatic changes may be of great importance ... -
Experimental evidence of threat-sensitive collective avoidance responses in a large wild-caught herring school
(Peer reviewed; Journal article, 2014)Aggregation is commonly thought to improve animals’ security. Within aquatic ecosystems, group-living prey can learn about immediate threats using cues perceived directly from predators, or from collective behaviours, for ... -
Experimental Evidence of Threat-Sensitive Collective Avoidance Responses in a Large Wild-Caught Herring School
(Journal article; Peer reviewed, 2014-01-29)Aggregation is commonly thought to improve animals' security. Within aquatic ecosystems, group-living prey can learn about immediate threats using cues perceived directly from predators, or from collective behaviours, for ... -
Experimental infection of turbot Scophthalmus maximus and halibut Hippoglossus hippoglossus yolk sac larvae with Aeromonas salmonicida subsp. salmonicida
(Journal article; Peer reviewed, 1997-04-24)The susceptibility of early life stages of turbot Scophthalmus maximus and halibut Hippoglossus hippoglossus to Aeromonas salmonicida subsp. salmonicida was studied in challenge experiments. Eggs of both fish species (and ... -
Experimental Parameterisation of Principal Physics in Buoyancy Variations of Marine Teleost Eggs
(Journal article; Peer reviewed, 2014-08-14)It is generally accepted that the high buoyancy of pelagic marine eggs is due to substantial influx of water across the cell membrane just before ovulation. Here we further develop the theoretical basis by applying laboratory ... -
Experimental transmission of piscine orthoreovirus-1 (PRV-1) in different life stages of Atlantic salmon (Salmo salar) and brown trout (Salmo trutta)
(Peer reviewed; Journal article, 2023)Piscine orthoreovirus -1 (PRV-1) causes the disease heart and skeletal muscle inflammation (HSMI) in farmed Atlantic salmon, and the virus has been detected in wild anadromous Atlantic salmon and brown trout. However, the ... -
Expert-driven methodology to assess and predict the effects of drivers of change on vulnerabilities in a food supply chain: Aquaculture of Atlantic salmon in Norway as a showcase
(Peer reviewed; Journal article, 2020)In the last decades, food produced by aquaculture has seen an impressive increase worldwide but maintaining high quality and safety is increasingly becoming a concern. It is apparent that changes in- and outside the ... -
Explaining decisions of deep neural networks used for fish age prediction
(Peer reviewed; Journal article, 2020)Age-reading of fish otoliths (ear stones) is important for the sustainable management of fish resources. However, the procedure is challenging and requires experienced readers to carefully examine annual growth zones. In ... -
Explicit incorporation of spatial variability in a biomass dynamics assessment model
(Peer reviewed; Journal article, 2021)The sustainable management of fisheries has largely relied on stock assessment models that assume stocks are homogeneous throughout their domain. However, ignoring complex underlying spatial patterns can lead to increased ... -
Exploration and learning of demand-feeding in Atlantic cod (Gadus morhua)
(Journal article; Peer reviewed, 2010-08-15)A bite–and–pull demand–feeding system was introduced to groups of cultured cod (Gadus morhua). For half of the groups trigger actuations were rewarded with food, while actuations were unrewarded in the other groups. ... -
Exploring balanced harvesting by using an Atlantis ecosystem model for the Nordic and Barents seas
(Peer reviewed; Journal article, 2020)“Balanced Harvesting” (BH) has been suggested as a possible strategy to meet the objectives of the Ecosystem Approach to Fisheries, ensuring a high sustainable yield while maintaining ecosystem structure and function. BH ... -
Exploring fishing impacts on the structure and functioning of the Yellow Sea ecosystem using an individual-based modeling approach
(Peer reviewed; Journal article, 2023)The Yellow Sea is a marginal sea in the Northwestern Pacific where the fishery resources have been overfished and the community structure has greatly changed over the past six decades. Ecosystem modeling approaches are ... -
Exploring the role of Northeast Atlantic cod in the Barents Sea food web using a multi-model approach
(Peer reviewed; Journal article, 2022)It is commonly accepted that no ecosystem model is the ‘best’, but rather that ecosystem models should be used in ensembles. This is also the case for the Barents Sea ecosystem, where we have used two different ecosystem ... -

(Peer reviewed; Journal article, 2022)It is commonly accepted that no ecosystem model is the ‘best’, but rather that ecosystem models should be used in ensembles. This is also the case for the Barents Sea ecosystem, where we have used two different ecosystem ... -
Exposure of cod Gadus morhua to resuspended sediment: an experimental study of the impact of bottom trawling
(Journal article; Peer reviewed, 2006-03-15)Bottom trawling activities resuspend large amounts of sediment and may be the main agent of sediment transportation in some areas. During periods of intensive fishing by large trawler fleets the high-turbidity environmental ... -
Expression and localization of the aryl hydrocarbon receptors and cytochrome P450 1A during early development of Atlantic cod (Gadus morhua)
(Peer reviewed; Journal article, 2020)The aryl hydrocarbon receptor (Ahr) is a ligand-activated transcription factor that mediates the toxicity of dioxins and dioxin-like compounds (DLCs) in vertebrates. Two clades of the Ahr family exist in teleosts (Ahr1 and ... -
Extending balance assessment for the generalized propensity score under multiple imputation
(Peer reviewed; Journal article, 2020)This manuscript extends the definition of the Absolute Standardized Mean Difference (ASMD) for binary exposure (M = 2) to cases for M > 2 on multiple imputed data sets. The Maximal Maximized Standardized Difference (MMSD) ...
