dc.description.abstract Back-tracking biomass values to 1932 for each posterior replicate of a Bayesian “Replacement Yield” model applied to the total annual catches and the survey abundance estimates for the South African kingklip resource off the South coast by Brandão and Butterworth (2013) results in both a mean and median current (2012) depletion of about 40%. This suggests current status close to BMSY, which taken together with the recent increasing trend in survey abundance estimates suggests a current fishing mortality less than FMSY. en_ZA
