Journal ArticleDOI
Towards a classification and an understanding of developmental relationships of vertebral body malformations in Atlantic salmon (Salmo salar L.).
TL;DR: Twenty types of salmon vertebral column malformations that are repetitively observed under farming conditions are proposed, based on radiological observations that have been obtained over the past 10 years from more than 5000 specimens.
Journal ArticleDOI
Aerobic training stimulates growth and promotes disease resistance in Atlantic salmon (Salmo salar).

TL;DR: In this paper, the effects of endurance training on disease resistance were evaluated using an IPN virus challenge test, while the cardiac immune modulatory effects were characterized by qPCR and microarray gene expression analyses.
Journal ArticleDOI
The effect of heat and cold exposure on HSP70 expression and development of deformities during embryogenesis of Atlantic salmon (Salmo salar)
TL;DR: Embryos subjected to the prolonged heat exposure showed a stronger HSP70 expression than embryos that were given a 1-h heat shock, supporting that early somitogenesis is an important period of left–right determination in teleosts.
Journal ArticleDOI
Molecular pathology of vertebral deformities in hyperthermic Atlantic salmon ( Salmo salar )
TL;DR: The presented data strongly indicates that temperature induced fast growth is severely affecting gene transcription in osteoblasts and chondrocytes; hence change in the vertebral tissue structure and composition.
Journal ArticleDOI
Ghrelin is involved in voluntary anorexia in Atlantic salmon raised at elevated sea temperatures.

TL;DR: It is suggested that lower circulating ghrelin during negative energy homeostasis induce down-regulation of GHSR1a-LR, neuropeptide Y, and anorexigenic factors at transcriptional levels in the hypothalamus, which over time lead to a voluntary anorexia development in adult salmon held at 19 °C.
