Abstract
Results are provided for a further 24 robustness tests for OMP2018. All tests have been conducted for the RC OM, and most do not have an appreciable impact on the assessment and projection results. The tests with the biggest impact were increasing or decreasing the proportion of the total fishing mortality in the offshore catch on M. paradoxus, adjusting the weights of the ALK and CAL data in the negative log-likelihood, accounting for discards and adjusting the ageing assumptions. None of these robustness tests, however, suggest serious concerns for the conservation of the hake resource when managed under OMP-2018.
