Résumé
We consider a stage structured model of a harvested fish population. The model is a discrete-time system involving a nonlinear recruitment function. Using Control Theory tools we show how to act on the fishing effort in order to prevent the extinction of the population. More precisely, we show how to compute the fishing effort as a feedback control (i.e., a function of the state) in order to maintain the fish population state around a desired steady state.
