    Abstract

    We provide extensive diagnostic plots for the 2017 models R1 and R3 for Antarctic toothfish in the Ross Sea as recommended by WG-SAM-15 (2015). The stock assessment rationale and models as well as their main diagnostics are described in Mormede (2017). The CASAL files for the assessment models were provided to the CCAMLR Secretariat as a zip file.

    In this paper we present the results for first inputs, model R1 and then model R3. The diagnostic plots cover input data, MPD and MCMC outputs. Key tables are given in Mormede et al. (2017) including process error weightings and the MPD objective function components.
