Antimicrobial susceptibility of Francisella noatunensis subsp. noatunensis strains isolated from Atlantic cod Gadus morhua in Norway
(Journal article; Peer reviewed, 2012-02-17)A total of 30 isolates of Francisella noatunensis subsp. noatunensis isolated from Atlantic cod Gadus morhua L. were tested for susceptibility, in the form of minimal inhibitory concentration (MIC) values, against the ... -
Are low but statistically significant levels of genetic differentiation in marine fishes ‘biologically meaningful’? A case study of coastal Atlantic cod
(Journal article; Peer reviewed, 2010-12-29)A key question in many genetic studies on marine organisms is how to interpret a low but statistically significant level of genetic differentiation. Do such observations reflect a real phenomenon, or are they caused by ... -

Comparative growth and survival of two genetic strains of Atlantic cod (Gadus morhua L.) reared through the early life stages in a marine pond in western Norway
(ICES CM Documents;1990/F:48, Working paper, 1990)The investigation was carried out in a marine pond in western Norway during spring and summer 1990. Two genetic defined strains of Atlantic cod (Gadus morhua L.) were used as broodstocks. A total of 11.1 x 10^6 cod larvae ... -
Economic repercussions of fisheries-induced evolution
(Journal article; Peer reviewed, 2013-07-23)Fish stocks experiencing high fishing mortality show a tendency to mature earlier and at a smaller size, which may have a genetic component and therefore long-lasting economic and biological effects. To date, the economic ... -
Effects on development, sex differentiation and reproduction of Atlantic cod exposed to produced water during early life stages
(Conference object, 2007-05-20)Two long term studies to assess the effects of produced water (0.01-1 %) on the early life stages of cod were performed. Experiment 1 examined the egg to early fry stage (90 days), and experiment 2 examined the early ... -
Egg distribution, bottom topography and small-scale cod population structure in a coastal marine system
(Journal article; Peer reviewed, 2007-03-12)Coastal marine species with pelagic egg and larval stages, such as the Atlantic cod Gadus morhua, can be structured into genetically distinct local populations on a surprisingly small geographic scale considering their ... -
EST resources and establishment and validation of a 16 k cDNA microarray from Atlantic cod (Gadus morhua)
(Journal article; Peer reviewed, 2010-06-28)The Atlantic cod, Gadus morhua, is an important species both for traditional fishery and increasingly also in fish farming. The Atlantic cod is also under potential threat from various environmental changes such as pollution ... -

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. ... -

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 ... -
The fate of vitellogenic follicles in experimentally monitored Atlantic cod Gadus morhua (L.): Application to stock assessment
(Journal article; Peer reviewed, 2010-05)In this paper we report on the fate of vitellogenic follicles (VF) as either alpha atretic follicles (αF) or post-ovulatory follicles (POFs) using histology and captive Atlantic cod (Gadus morhua) in three experiments. In ... -

Fecundity and growth of Atlantic cod (Gadus morhua L.) along a latitudinal gradient
(Journal article; Peer reviewed, 2010-05)Some fish species have wide distribution areas that span very different habitats. In this investigation we have studied Atlantic cod (Gadus morhua), which is an example of such a species, to demonstrate how this may have ... -
Genetic assignment as a tool to identify the origin for Atlantic cod (Gadus morhua) escapees in Norwegian fjords
(ICES CM documents;2009/Q:14, Working paper, 2009) -
Genetic diversity within and among Atlantic cod (Gadus morhua) farmed in marine cages: a proof-of-concept study for the identification of escapees
(Journal article; Peer reviewed, 2010-03-23)This study presents a molecular genetic characterization of Atlantic cod reared in commercial marine farms. Samples consisted of approximately 47 fish collected from nine cages located on four farms throughout Norway. In ... -
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 ... -
