2013 Update of the Reference Set of Operating Models used in testing Candidate OMPs for the South African hake resource

A Reference Set (RS) of 12 scenarios was selected as the primary basis to be used to simulation test candidates for OMP-2011 (Rademeyer and Butterworth, 2010). This paper presents an update of this RS, based on updated commercial data (catches, trawl and longline length distribution and trawl CPUE), some revisions of biological parameter values, and new survey data (biomass estimates and length distributions) until January 2012.
