During 2013, the Chilean fishing law was amended to incorporate, among other changes, the maximum sustainable yield (MSY) as target reference point for managing fishery resources. This mandate triggered the estimation of MSY-based reference points (RPs) in each fishery subject to catch limits in Chile. Recent investigations indicate that production models provide MSY-based RPs, which are predicted only by using the steepness of the stock-recruitment relationship ( h ). In this paper, we compare predicted MSY-based RPs using production models with estimates from an age-structured per-recruit model for eleven demersal stocks harvested in Chile.
