Analysis of coastal cod (Gadus morhua L.) sampled on spawning sites reveals a genetic gradient throughout Norway's coastline
(Journal article; Peer reviewed, 2018)Atlantic cod (Gadus morhua L.) has formed the basis of many economically significant fisheries in the North Atlantic, and is one of the best studied marine fishes, but a legacy of overexploitation has depleted populations ... -
Atlantic salmon populations invaded by farmed escapees: quantifying genetic introgression with a Bayesian approach and SNPs
(Journal article; Peer reviewed, 2013-08-23)Background Many native Atlantic salmon populations have been invaded by domesticated escapees for three decades or longer. However, thus far, the cumulative level of gene-flow that has occurred from farmed to wild salmon ... -
Chromosome aberrations in pressure-induced triploid Atlantic salmon
(Peer reviewed; Journal article, 2020)Triploid organisms have three sets of chromosomes. In Atlantic salmon, hydrostatic pressure treatment of newly fertilized eggs has been extensively used to produce triploids which are functionally sterile due to their ... -
Development of supermale and all-male Atlantic salmon to research the vgll3 allele - puberty link
(Peer reviewed; Journal article, 2020)Farmed Atlantic salmon are one of the most economically significant global aquaculture products. Early sexual maturation of farmed males represents a significant challenge to this industry and has been linked with the vgll3 ... -
Epistatic regulation of growth in Atlantic salmon revealed: a QTL study performed on the domesticated-wild interface
(Peer reviewed; Journal article, 2020)Quantitative traits are typically considered to be under additive genetic control. Although there are indications that non-additive factors have the potential to contribute to trait variation, experimental demonstration ... -
Genome wide analysis reveals genetic divergence between Goldsinny wrasse populations
(Peer reviewed; Journal article, 2020)Marine fish populations are often characterized by high levels of gene flow and correspondingly low genetic divergence. This presents a challenge to define management units. Goldsinny wrasse (Ctenolabrus rupestris) is a ... -
Hybrids between common and Antarctic minke whales are fertile and can back-cross
(Journal article; Peer reviewed, 2013-04-15)Background: Minke whales are separated into two genetically distinct species: the Antarctic minke whale found in the southern hemisphere, and the common minke whale which is cosmopolitan. The common minke whale is further ... -
Investigating the frequency of triploid Atlantic salmon in wild Norwegian and Russian populations
(Journal article; Peer reviewed, 2018)Fish may display variations in ploidy, including three sets of chromosomes, known as triploidy. A recent study revealed a frequency of ~ 2% spontaneous (i.e., non-intentional) triploidy in domesticated Atlantic salmon ... -
Pacific and Atlantic Lepeophtheirus salmonis (Krøyer, 1838) are allopatric subspecies: Lepeophtheirus salmonis salmonis and L. salmonis oncorhynchi subspecies novo
(Journal article; Peer reviewed, 2014-03-14)Background The salmon louse Lepeophtheirus salmonis is a parasitic copepod that infects salmonids in the Pacific and Atlantic oceans. Although considered as a single species, morphological and biological differences have ... -
Ploidy elicits a whole-genome dosage effect: growth of triploid Atlantic salmon is linked to the genetic origin of the second maternal chromosome set
(Peer reviewed; Journal article, 2017) -
Production and verification of the first Atlantic salmon (Salmo salar L.) clonal lines
(Peer reviewed; Journal article, 2020)In several fish species homozygous and heterozygous clonal lines have been produced using gynogenetic and androgenetic techniques. These lines are standardized and can be reproduced over generations. In rainbow trout such ... -
The frequency of spontaneous triploidy in farmedAtlantic salmon produced in Norway during theperiod 2007–2014
(Journal article; Peer reviewed, 2015-04-11)Background: Spontaneous triploidy has been reported in a number of fish species, and is often linked with in vivo or in vitro ageing of eggs post ovulation. Here, we provide the first investigation into the frequency of ... -
The influence of vgll3 genotypes on sea age at maturity is altered in farmed mowi strain Atlantic salmon
(Journal article; Peer reviewed, 2019)Background: In Atlantic salmon in the wild, age at maturity is strongly influenced by the vgll3 locus. Under farming conditions, light, temperature and feeding regimes are known significantly advance or delay age at ... -
Transcriptomic comparison of communally reared wild, domesticated and hybrid Atlantic salmon fry under stress and control conditions
(Peer reviewed; Journal article, 2020)Domestication is the process by which organisms become adapted to the human-controlled environment. Since the selection pressures that act upon cultured and natural populations differ, adaptations that favour life in the ...
