Performance statistics are contrasted for seven hake CMPs: three options for the b control parameters crossed with two options for the cap on the TAC, and further a no cap option for the b+5% option. Despite a higher average catch, the no cap option seems undesirable because of poor lower 5%ile depletion and high AAV values. Instances of low 5%ile depletion values for M. capensis are shown to be linked to three likely less plausible OMs amongst the nine OMs that make up the Reference Set. However, in those cases, with the 2017 starting M. capensis spawning biomasses below BMSY, the CMPs would seem to secure a recovery towards BMSY. Based on these results, the DAFF DWG decided to propose the b+5% option with a cap of 160 000t on the annual TAC.
