Synopsis An age-structured simulation model of the growth and population dynamics of a migratory rainbow trout population is presented. The model includes all principal life-history intervals and incorporates the food density-temperature relationships of salmonid growth efficiency proposed by Brett et al. (1969) and Shelbourn et al. (1973). Population size, mean weight, and biomass are adjusted and output monthly over time in age, sex, and location categories; a simulation run may continue for as long as 100 years. A variety of environmental and and biological parameters are utilized in the simulation which can be altered as a user option. Simulation results compare favorably with field data. Sensitivity analyses illustrate the importance of age-sex specific maturation ratios, age-class strength fluctuations, and natural mortality rates in determining population size.
