Figures 1 and 2 plot spawning biomass and recruitment results respectively for a retrospective analysis of the South African hake resource for the 2017 Reference Case (Rademeyer and Butterworth, 2017).
Over recent years the assessment has tended to somewhat underestimate M. paradoxus and somewhat overestimate M. capensis spawning biomass. There are no obvious retrospective patterns in recruitment estimates, though recent recruitment for both species was appreciably overestimated for the assessment when ended in 2012.
