Detailed SR Function Description
Percent survival of rainbow trout (gray circles, gray line in image) in relation to test temperature during a 60-d experiment. Rainbow trout survival was similar (98.6–100%) among temperatures of 8–22C but declined significantly (P , 0.05) at higher temperatures: survival was 72.8% at 24C, 2% at 26C, and 0% at 28C.
In this laboratory experiment, Rainbow trout were obtained as eggs from the Ennis National Fish Hatchery near Ennis, Montana.
Survival formula is as follows:
Survival = 97.8846/1+e^-((temperature-24.3522)/-0.5033)
Function Derivation
laboratory experiment
