Abstract

This document provides final CMP trial results for the revision of the SA hake OMP, following selections and requests made at the 16 September meeting of the DWG. The results cover the four CMPs identified, which are distinguished by two different target average TACs for the next decade, and by whether or not the TAC is fixed at 147 500 tons for the next two years. For the higher target average TAC (138 000 t compared to 135 000 t), M. paradoxus recovery would be about 5% and CPUE about 2% less, with attainment of MSYL delayed by about 2 years. For the options with a fixed TAC of 147 500 t for the next two years, recovery is briefly delayed, and later TACs drop lower, with lower CPUEs and higher effort levels over most of the next decade. Performance under the various robustness tests examined does not seem unsatisfactory.
