Abstract

A preliminary integrated stock assessment model was constructed for Dissostichus mawsoni at the research block 48.6_2, as a test run for integrated assessment model for stock assessment of D. mawsoni at Subarea 48.6. Our preliminary analysis is problematic as a stock assessment, but indicates future tasks for improvement: further sensitivity analysis of IUU, addition of ageing data and modeling of migration.
