Hepatic Expression of Growth Hormone Receptor (<i>GHrec</i>) and Insulin-like Growth Factor-I (<i>IGF-I</i>) Genes and Cellular Location of <i>IGF-I</i> mRNA in Diploid and Triploid Atlantic Salmon (<i>Salmo salar</i>) Undergoing Parr-Smolt Transformation.

ABSTRACT: The induction of triploidy, a strategy to mitigate unwanted pre-harvest sexual maturation and a genetic containment measure for escaped farmed Atlantic salmon (Salmo salar), may give rise to challenges because of the distinct environmental and dietary requirements of sterile triploid fish. Smoltification is a critical phase in the life cycle of Atlantic salmon, so knowledge about parr-smolt transformation in triploids is important for the salmon farming industry. This study covered an investigation of hepatic expression of growth hormone receptor (GHrec) and insulin-like growth factor-I (IGF-I) genes, both of which are intimately involved in the regulation of osmoregulation and growth. Additionally, hepatic presence and location of IGF-I mRNA were examined using
