Presently available fishery models are either too simplified or too complicated to be useful to inland fishery managers. This research was directed toward developing a simplified but realistic computerized simulator useful to fishery managers. The model developed is basically an ageclass structured simulator with features built in to allow easy but effective use by fishery managers. It includes provisions for input of all important parameters plus provisions for density-dependent relationships where applicable. Examples of model use are given for a put-and-take rainbow trout (Salmo gairdneri) fishery and a self-sustaining walleye (Stizostedion vitreum) population.
