; 2) the ratio between the fishing mortality that gives the MSY and natural mortality ; and 3) the ratio of spawning biomass per recruit (SR) when the population is fished at Fmsy to the spawning biomass per recruit of an unfished population . The production model provides and SPRmsy that well predicted estimates from the age-structured models in most of the species analyzed. However, was overestimated by the production model in most of the stocks. We discuss the dependence of h with the MSY-based RPs in light of the Chilean fishing law. This paper reveals the complexity of implementing the Chilean Fishing Law into real situations and the uncertainty surrounding the estimation of h and, by extension, MSY and MSY-based RPs.]]>
