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 as a driving force of life history evolution: methods and empirical analyses
(ICES CM documents, Working paper, 2004)Today, fishing is the dominant source of mortality in most commercially exploited fish stocks. Life-history theory predicts that, under most circumstances, increased mortality at potential ages and sizes at maturation ... -
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 -
The Exploitation of the Spiny Dogfish (Squalus acanthias L.) in European Waters
(Fiskeridirektoratets skrifter, Serie Havundersøkelser, Research report, 1964)The present paper is a short account of the state of the stock in recent years of Squalus acanthias in European waters. The basic material is the catch statistics from Bulletin Statistique (ICES), the Norwegian spur-dog ... -
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 ... -
Extended survey report from the joint Norwegian/Russian ecosystem survey in the Barents Sea August-October 2004, Volume 2
(IMR/PINRO joint report series, Research report, 2005)The main aim of the ecosystem survey was to map the distribution and abundance of the young and adult stages of several demersal and pelagic fish species, and in addition to this gather information about hydrographical ... -

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 ... -
Extensive gas bubble release in Norwegian spring spawning herring (Clupea harengus) during predator avoidance
(ICES CM Documents;1998/J:20, Working paper, 1998)Events of extensive gas bubble releases in overwintering Norwegian spring spawning herring (Clupea harengus) were repeatedly observed acoustically and visually in Vestfjorden, northem Norway, during attacks from killer ...
