Abstract

The results from robustness tests of the OMP adopted last year for the hake resource are used to assign priorities for research, with the outcome compared to that from the Environmental Risk Analysis (ERA) exercise. Broad similarities are evident, with both approaches indicating that improved information on the extent of recruitment variability and on the species (also sex) composition of the commercial catches is a high priority. However the OMP approach suggests low priority for M. capensis size structure issues, in contrast to the ERA. Key research needs, roughly in order of priority, are seen to be: ageing, sampling the commercial catches for species and sex, improved precision of abundance indices, improved information on discards, and (primarily in a trans-boundary context) genetic analyses to detect possible stock structure.
