Detailed SR Function Description
Percent daily relative growth rate of juvenile westslope cutthroat trout in relation to temperature during a 60-d experiment.
In this laboratory experiment, Westslope cutthroat trout used in experiments were either eggs or age-0 fish from a wild stock at Rogers Lake, Montana, or age-0 fish from wild stock maintained at the Westslope Trout Company, a private fish hatchery near Ronan, Montana. Both sources are derived from a mixture of pure populations of westslope cutthroat trout from Montana.
Growth formula is as follows:
Growth = -4.1727 + 0.9496 * temp - 0.0348 * (temp)^2
Scaled from the original curve so that the highest upper limit value equals to 100%.
