Abstract:

In this study we apply an age-structured bio-economic model to the Ibero-Atlantic sardine stock, and compute an optimal harvesting strategy. We compare it with the ongoing harvest control rule. We show that an optimal plan may entail greater net returns from the fishery, though at a cost of reducing biomass below acceptable reference points. By incorporating precautionary constraints we find that an optimal plan is still able to yield higher economic returns, while it accommodates stock-recovery objectives.
