At the previous SWG meeting (23 March 2011) results of updated operating models for all five super-areas of the west coast rock lobster resource were presented (Johnston and Butterworth 2011). The SWG requested that two of the operating models be re-run following discussions at the meeting. These re-runs are: Area 1+2: Re-run the model with the constraint that all estimable recruitment parameters must be 1.0, when expressed as a proportion of the pristine recruitment. Area 8+: Re-run the model with updated values for both the trapboat and hoopnet CPUE series. Glazer and Butterworth (2011a,b) report updated CPUE values. These values have been updated to include Area 8 sub-areas and to take into account Areas 10-14 as recommended.
