Abstract
  • A growth model is developed for coho salmon which accounts for temperatures and feeding rates typically encountered in fish hatchery operation. Feeding rates utilized by the model ranged from maintenance to maximum utilizable rations. The model is derived from an empirical equation for maximum growth rate, and a theoretical equation for net energy utilization. The resultant equation is modified to improve fit at higher feeding levels. Calibration is accomplished with experimentally obtained data. The model is similar to one developed by G.D. Stauffer, but represents an improvement because points on the growth curve between maintenance and maximum ration can be fitted even if maintenance and maximum requirements are obtained independently. An optimization method is then developed using this growth model that determines, for a given temperature regime, a feeding schedule that minimizes total food consumption for a given rearing period. The method is then extended to determine simultaneously feeding schedules and temperature regimes that minimize total food consumption.
