2012 Routine update of the South African hake reference case assessment

2012
This paper presents a routine update of the South African hake Reference Case assessment (RS1) (Rademeyer and Butterworth, 2010), including new commercial (catches and CPUE) and survey (abundance estimates and length distribution) data. This analysis does not include post-2009 commercial length distribution data whose finalisation is still in progress.

And yet further candidate management procedure testing for the South African hake resource

2010
This document reports progress on hake OMP revision issues identified at the last DWG meeting as requiring further attention. In particular it updates the Reference Case CMP in terms of the agreements reached at that meeting. Suggestions are made for the final set of calculations needed before a selection is made amongst CMPs at the following DWG ...

An initial attempt at a spatially structured stock assessment for the South African hake resource

2008
This document presents a first attempt at a spatially structured model for the South African hake (the model equations are set out in Appendix 1). It is currently assumed that M. paradoxus and M. capensis both consist of a single stock across the South African west and south coasts (and possibly extending to Namibia).

Proposed reference set for the South African hake resource to be used in OMP-2010 testing

2010
A Reference Set (RS) of 12 scenarios is put forward as the primary basis to be used to simulation test candidates for the revised OMP for hake, OMP-2010. The principal uncertainty axes spanned by this RS are the central year for the switch from a primarily M. capensis to a primarily M.
