Abstract
We examine harvest strategies for two models of an exploited ecologica l system. For the model with constant growth and death rates, an optim al constant harvest strategy is obtained. For the model with uncertain ty occurring in the system parameters, a harvest strategy is proposed which stabilizes the biomass of the ecological system about a desired level, namely, the level generated by the optimal constant harvest str ategy in the absence of uncertainty.
