“…The common-held belief that the ratio of the current stock size to the stock size in some historical year is estimated more robustly than recent stock size in absolute terms (e.g., Punt 1989;Punt et al 2002) was therefore not supported for rock lobster off Victoria. Similar conclusions were drawn by Punt et al (2002) based on age-structured models and by Punt (2003) based on a size-structured model.…”

The management strategy evaluation (MSE) approach was used to evaluate management strategies based on the current method of stock assessment for rock lobster (Jasus edwardsii) off Victoria, Australia, and decision rules inferred from the management plan for Victorian rock lobster and past practice when selecting total allowable catches, TACs. The results are expressed in terms of whether it is possible to keep stocks above limit reference points with high probability and recover overexploited stocks to the target level. Three categories of management strategy were examined using the MSE, which differed in whether assessments were conducted, and TACs set, by management zone or by region within management zone. A management strategy based on conducting assessments and setting TACs by management zone is most similar to the way assessments are currently conducted and management regulations implemented for rock lobster off Victoria. However, this management strategy performed poorest in recovering stocks to target levels. Alternative management strategies which involved conducting assessments and setting TACs by region performed better, but may have practical limitations. The assessment method was found to be generally relatively accurate and precise, although estimation performance was poor/imprecise on occasion.

“…These data are assumed to be measured without error. No errors are assumed between the boundaries used for stock assessment and the true boundaries among the stocks, although this could be examined in future using the methods of Punt et al (1995) and Punt (2003). Once the data have been generated, they are analyzed using the stock assessment component of the management strategy and then by its decision rule component.…”
