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 ... -
Exploitation of Antarctic krill Euphausia superba by three air-breathing predators with contrasting foraging strategies – implications for fisheries feedback management
(Conference object, 2016)SCAR Open Science Conference, Kuala Lumpur 2016 -
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 ... -

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) ... -
Extension of the match-mismatch hypothesis to predator-controlled systems
(Journal article; Peer reviewed, 2013-01-31)Differential change in the phenology of predators and prey is a potentially important climate-mediated mechanism influencing populations. The match-mismatch hypothesis describes the effect of predator-prey population ... -
Extent and ecological importance of escape through spawning in sea-cages for Atlantic cod
(Journal article; Peer reviewed, 2012-11-14)The culture of certain fish species to sizes at which they can reproduce has led to the escape of fertilised eggs or ‘escape through spawning’. To investigate the extent and ecological importance of spawning in sea-cages ... -
Extreme male-skewed sex ratios on spaning grounds for Atlantic cod Gadus morhua with typical coastal cod signatures of the Pan I (pantophysin) locus
(Journal article; Peer reviewed, 2015-06-11)Large offshore and small inshore populations of Atlantic cod Gadus morhua L. display differences in migratory patterns and settling regimes, but little is known about possible differences in spawning behaviour. Cod presumably ... -

Factors influencing risk assessments of brominated flame-retardants; evidence based on seafood from the North East Atlantic Ocean
(Journal article; Peer reviewed, 2018)Brominated flame-retardants (BFRs) such as polybrominated diphenyl ethers (PBDE) and hexabromocyclododecane (HBCD) are considered hazardous to human health. Due to their persistence, they are still present in the environment ... -
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 ... -
Fangst og mellomlagring av villfisk ved oppdrettsanlegg
(Nofima rapportserie, Research report, 2012)Den merdbaserte produksjonen av laks i norsk oppdrettsnæring har økt betydelig det siste tiåret, og var nær 1 million tonn i 2010. Lokalitetene som benyttes i denne produksjonen blir stadig større, og produksjonen på flere ...
