| dc.description.abstract | Results are presented for a series of sensitivities to the new baseline assessment (NBA) for the South African hake resource (Rademeyer and Butterworth, 2008). The selection of these sensitivities follows in part from issues/concerns in the assessment used for the last OMP that need further consideration in specifying Operating Models (OMs) for the next OMP revision. These include the use of catch-at-length (CAL) information for years where age-length keys (ALKs) are not available, perceptions of the relative status of the two species, the appropriateness of the survey-based algorithm to split the offshore trawl catches by species and the values of the survey constant of proportionality (from swept area estimate to total biomass in absoluter terms). | en_ZA |
