dc.description.abstractThis document reports assessment results for the five final 2010 operating models (OMs) used to update the South Coast rock lobster resource assessments. These OMs contain the following modifications from the versions reported in Fisheries/2010/JUL/SWGSCRL/08: • Somatic growth parameters estimated during fitting procedure to be used for all length-at-weight relationships. • Mean of recruit residuals over 1974-2000 period forced to zero. The five OMs are: 1. Model 3 (MARAM time-varying selectivity) 2. Model 4 (OLRAC time-varying selectivity) 3. Effort Saturation (Model 3 but with effort saturation included – see Appendix for methodology) 4. CAL-down-weight (Model 3 but catch-at-length data down-weighted by a multiplicative factor of 0.1) 5. Fix h=0.8 (Model 3 but with stock recruitment steepness parameter h fixed at 0.8).en_ZA
