In the MR the data generated by the OM are used in an assessment that generates an observed (or "perceived") stock, which is, in turn, fed into a harvest control rule resulting in a management action (e.g. a total allowable catch [TAC] or allowable fishing effort). It is the presence of this feedback control that distinguishes MSE from risk analysis or projections. Stakeholders/decision-makers must be involved in the identification of the general goals of the MSE (i.e. the management objectives) and of the management strategies to be simulated. The final results should be presented clearly, allowing decision-makers to take decisions on the final management strategy to be adopted and to make the policy call.
