Abstract
This document reports such updated stock assessments for the South Coast rock lobster fishery. Essentially three further years’ CPUE and catch-at-length data are available since the assessments upon which OMP testing was based were carried out
in 2008 (see Johnston and Butterworth 2008a). Assessment updates produced in 2009 are now able to be further updated with one years’ data. Although Johnston and Butterworth (2008a) initially presented stock assessment results for a wide range of models, only Models 3 and 4 were used as a final Reference Set in final OMP deliberations. Updates of Models 3 and 4 are thus presented here.
