    Performance of the empirical management procedure (MP2) under the updated operating models
    (2011) Kurota, Hiroyuki; Takahashi, Norio; Sakai, Osamu; Butterworth, Doug S
    We evaluated the performance of the empirical management procedure (MP2) using the updated operating model (reference set and robustness trials). In order to meet management targets, TACs need to be increased steadily and substantially under the updated reference set, and the MP behavior is different from that under the previous reference set used at the 2010 ESC meeting. This is because the updated operating model estimates a very productive stock at present due to higher steepness and recent good recruitments. Tuning options, particularly regarding the maximum allowable change of TAC, would need to be reconsidered when using this optimistic operating model for performance evaluation of MPs.
