    Abstract

    We provide extensive diagnostic plots for models R1 and R2 for Antarctic toothfish in the Ross Sea as recommended by SAM-2015 (2015). The stock assessment rationale and models as well as their main diagnostics are described in Mormede et al. (2015). The CASAL files for models R1 and R2 were provided to the CCAMLR Secretariat as a zip file.

    In this paper we present the results for first model R1 and then model R2. The diagnostic plots cover input data, MPD and MCMC outputs. Key tables are given in Mormede et al (2015) including process error weightings and the MPD objective function components.
