The integrated assessment for Antarctic krill (Euphausia superba) in CCAMLR Subarea 48.1 has been under development since 2010. Progress on the model during this period was reported in a series of papers and presentations to WG-EMM, WG-FSA and WG-SAM from 2011 to 2016. The full text of the recommendations extracted from the CCAMLR Scientific Committee reports regarding the integrated krill assessment during that period is included as an Appendix to this document.
The purpose of this paper is to summarize the recommendations from CCAMLR Working Groups and the Scientific Committee that have been made to date along with a description of how the model has incorporated those suggestions, and to obtain advice from WG-SAM regarding whether the parameter estimation portion of the current model appears mature enough to use for representing the population/subpopulation represented by krill in Subarea 48.1, or, if not, what modifications or additions are required. This paper is focused on parameter estimation and does not include using the integrated model to make future projections to determine if candidate levels of harvest meet decision rules. The future projection components of the integrated krill model are undergoing revision following WG-SAM-2016.
