Resumo: | The simple surplus production model introduced is called Local Surplus Production Model (LSPM) because its only assumption is that the mean surplus production remains constant during a short period of years previous to the date of assessment. Its application requires only a short series (3-4 years) of values of an abundance index proportional to the mean real abundance of the resource. The model parameters estimate is performed in a Bayesian context using the SIR (Sampling Importance Resampling Algorithm) algorithm. Simple risk criteria to assess the Maximum Biologically Acceptable Catch and the risks associated to each hypothetical catch level considered are proposed. Application of the model to the whitemouth croaker (Micropogonias furnieri) resource is shown. Finally, a simulation exercise to evaluate the statistical performance of the LSPM is performed.
