[Immediate effects of thermal shocks on the plasma level of various components in the Rainbow trout: compounds indicating stress and protein fraction].
Rainbow trout were subjected to thermal shocks (9 degrees water temperature increase, 1 hr stay at 21 degrees and return to initial temperature) at the rate of 2 shocks a day during 1 day or 3 successive days. The observed changes only show a moderate reaction. cAMP does not vary; lactate slightly increases at 17 hr after the end of the shocks. Glucose seems to be the most reliable stress indicator; it increases at 2 hr and remains again above control value at 17 hr after a 3 day shock time. Fibrinogen increases after a 3 day shock time. Lastly, a strong decrease in low density lipoprotein level is seen at 17 hr following both shock duration times and from 2 hr in case of a 3 day shock time.
