Resumo: | Based on the Schaefer production model, an stochastic model is described, that is a model in which noises perturbing biomass and measurements are considered, serving to describe random variations in mortality and recruitment as well as some inaccuracies in measurements taken. The model is discrete, linear and adaptable, and the parameters biomass and noises intensities are restimated with each new measurement obtained. The problem of regulation is solved, on the basis of the model described, through fishing effort that should be applied to keep biomasss close to equilibrium. Computer effected simulations are presented.
