Genomic organization and gene expression of the multiple globins in Atlantic cod: conservation of globin-flanking genes in chordates infers the origin of the vertebrate globin clusters
(Journal article; Peer reviewed, 2010-10-20)Background: The vertebrate globin genes encoding the α- and β-subunits of the tetrameric hemoglobins are clustered at two unlinked loci. The highly conserved linear order of the genes flanking the hemoglobins provides a ... -
Horizontal transmission of nervous necrosis virus between turbot Scophthalmus maximus and Atlantic cod Gadus morhua using cohabitation challenge
(Journal article; Peer reviewed, 2012-05-15)Experimental horizontal transmission of nervous necrosis virus (NNV) originating from halibut Hippoglossus hippoglossus was studied through cohabitation of intraperitoneally (i.p.) injected fish with uninfected fish for ... -
Implications of fisheries-induced evolution for stock rebuilding and recovery
(Journal article; Peer reviewed, 2009-07-31)Worldwide depletion of fish stocks has led fisheries managers to become increasingly concerned about rebuilding and recovery planning. To succeed, factors affecting recovery dynamics need to be understood, including the ... -
Kartlegging av gytefelt
(Fisken og Havet;1-2013, Research report, 2013-01)Gytefelt er et nøkkelområde for reproduksjon hos fisk, og gytefelt for kysttorsk kartlegges gjennom ”Nasjonalt program for kartlegging av marine naturtyper”. Målsettingen med kartleggingen er å stedfeste og verdisette ... -
Life history of fjord cod from the Skagerrak in the mid-2000s compared to 1905
(Journal article; Peer reviewed, 2011-03-01)Life history changes serve as stress indicators in harvested populations. Data from recent decades show that many species of marine fish are now maturing at younger ages and smaller sizes, associated with a general increase ... -
New perspectives on fish movement: kernel and GAM smoothers applied to a century of tagging data on coastal Atlantic cod
(Journal article; Peer reviewed, 2008-12-09)Tagging–recovery studies have been used successfully on many occasions, and the data analysed in a variety of ways with respect to fish movement. Here we provide a synoptic account of useful statistical techniques for ... -
Nodavirus in farmed Atlantic cod Gadus morhua in Norway
(Journal article; Peer reviewed, 2007-09-14)Viral encephalopathy and retinopathy (VER) was diagnosed in 5 to 24 g sized farmed Atlantic cod Gadus morhua kept in sea cages at Parisvatn, Hordaland county, on the west coast of Norway. Moderate mortality (10 to 15%) ... -

Occurence and structure of cysts in x-cell lesions of Atlantic cod (Gadus morhua L.)
(ICES CM Documents;1994/E:12, Working paper, 1994)Introduction: Despite numerous investigations the nature and origin of x -cells remain unknown. These ovoid, pale-staining cells with a large, round nucleus and prominent nucleolus are known to occur in the form of ... -

Recruitment of Atlantic cod stocks in relation to temperature and advection of copepod populations
(Journal article; Peer reviewed, 2000-11)The recruitment of Atlantic cod stocks shows different responses to temperature changes. Cod stocks inhabiting the lower temperature range show generally an increase in recruitment with increasing temperature, while cod ... -

Recruitment Variability in North Atlantic Cod and Match-Mismatch Dynamics
(Journal article; Peer reviewed, 2011-03-07)Background Fisheries exploitation, habitat destruction, and climate are important drivers of variability in recruitment success. Understanding variability in recruitment can reveal mechanisms behind widespread decline in ... -
Report of the Workshop on the Decline and Recovery of cod Stocks throughout the North Atlantic, including trophodynamic effects (WKDRCS) [9–12 May 2006 St.John's, Canada]

RNA deep sequencing of the Atlantic cod transcriptome
(Journal article; Peer reviewed, 2010-05-20)The Atlantic cod (Gadus morhua) is an emerging aquaculture species. Efforts to develop and characterize its genomic recourses, including draft-grade genome sequencing, have been initiated by the research community. The ... -

Small-scale genetic structure in a marine population in relation to water circulation and egg characteristics
(Journal article; Peer reviewed, 2010-10)Until the last decade it was assumed that most marine species have pronounced gene flow over vast areas, largely because of their potential for dispersal during early life stages. However, recent genetic, modeling, and ... -
Spatial scale of genetic structuring in coastal cod Gadus morhua and geographic extent of local populations
(Journal article; Peer reviewed, 2007-08-07)We estimated the spatial scale of genetically distinguishable populations of coastal Atlantic cod Gadus morhua using microsatellite DNA markers. Significant overall heterogeneity in allele frequencies was found among 5 cod ... -
Spawning stock and recruitment in North Sea cod shaped by food and climate
(Journal article; Peer reviewed, 2010-09-01)In order to provide better fisheries management and conservation decisions, there is a need to discern the underlying relationship between the spawning stock and recruitment of marine fishes, a relationship which is ...
