dc.description.abstractThe assessment methodology for the hake resource is refined to take account of recommendations made by the Panel at the December 2008 International Stock Assessment Workshop to move to a gender-disaggregated model, and to fit directly to age data and estimate growth curve parameters directly in the likelihood maximisation process. This approach proves to remove the conflict between fits to catch-at-age and catch-at-length distributions evident in earlier assessments. The current M. paradoxus female spawning biomass is estimated to be at 76% of its MSY level, while the corresponding M. capensis estimate well above this level.en_ZA
