Growth hormone and insulin-like growth factor-I act together and independently when regulating growth in vertebral and muscle tissue of Atlantic salmon postsmolts.

^Aiming to elucidate the role of GH and IGF-I with regard to vertebral and white muscle growth, gene expression of the GH and IGF-I receptors (ghr and igf-Ir, respectively) and local IGF-I (igf-I) were analyzed during spring growth (January-June) in Atlantic salmon postsmolts. One group of fish was reared under natural light (NL), while one group was reared under continuous light (LL). Growth rate of fork length was higher in the LL group for a short period after onset of continuous light (LL: 0.50
