| Abstract |
The effect of starvation on plasma hormone and metabolite in rainbow trout Oncorhinchus Mykiss was investigated. Plasma somatolactin (SL) were found to be significantly lower in starved than in fed fish, whereas plasma growth hormone (GH) levels were significantly elevated during starvation. Changes in plasma free fatty acids, glucose, protein, amino acids and liver glycogen occured as expected in the starved fish. Regression analyses indicated that both SL and GH levels were significantly correlated to most of the metabolic parameters measured; however the regression lines for SL and GH were always oposite to each other.The results indicate that SL, as well as GH, may be involved in some aspect of energy metabolism control. |
