6. Developing robust biomass estimates and advice on catch limits in research blocks

   Abstract:  In 2016, changes to the methods used by CCAMLR to estimate biomass in research blocks ... resulted in conflicting estimates of biomass between the CPUE by seabed area and the Chapman estimate. The ... different biomass estimates be provided. In this paper, we develop a modified CPUE by seabed area method ... that improves on the original CPUE by seabed area method for toothfish populations in research blocks ...
