FISHERIES/2016/SEP/SWG-DM/51 provided a full description of the current stock assessment model for the South African Horse Mackerel. FISHERIES/2016/SEP/SWG-DM/52 reported updated 2016 assessments for a number of model variants where the assessments were extended to allow for better fits to the low CPUE values (2014-2015). This document here provides updated 2017 assessment results for a number of model variants which follow on from the variants that were explored in 2016 and take the data from 2016 now available into account.
