Phase-randomisation in an integrated assessment model for Antarctic krill
Abstract: An integrated model was configured to estimate eighteen different subsets of 119 total parameters in alternative configurations of a model assessing the status and productivity of Antarctic krill (Euphausia superba, hereafter krill). We fixed the parameters that were not estimated in any

Comparison of bootstrap methods for assessment of mackerel icefish (Champsocephalus gunnari) in CCAMLR Statistical Subarea 48.3 based on the ground fish survey
Abstract: The existing bootstrap used in the assessment of icefish biomass in CCAMLR subarea 48.3 was compared to an alternative rescaled bootstrap to compare the performance of the methods. The differences between the method were small (less than 5%) except for slightly lower 5%iles in 2002 and

Sensitivities in the assessment of the Patagonian toothfish (D. eleginoides) in Subareas 48.3 and 48.4 to truncation of tagging data
Abstract: The assessment of toothfish in CCAMLR subarea 48.3 currently uses the first four years of tag recaptures post release as input data, whereas the assessment in subarea 48.4 uses all available recapture data (excluding in-year recaptures). A theoretical analysis of the use of data from

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 Scientific Committee requested that the changes to the methods be reviewed, that scientific

Simulations to evaluate model performance for Antarctic toothfish stock assessment in the Amundsen Sea region
Abstract: The Amundsen Sea region (ASR) is currently managed under a research plan, which has shown promising results to date, with 8 interseason tags recaptured in the South area in 2016 and 12 (preliminary recaptures) in 2017. The aim of this paper is to ascertain when the Amundsen Sea region
