The natural mortalities-at-age indicated by an explicit model of hake predation on hake are compared with those assumed for the Rademeyer and Butterworth (2014) Reference Case Operating Model. This RC model is re-run with the 1984-2014 average natural mortality rates at age from the predation model and the results compared. The main difference is in estimates of BMSY and of the status of each species relative to that biomass level.
