    Resumen

    This document outlines plans by Australia to conduct an acoustic biomass survey for krill in CCAMLR Division 58.4.2 (the South West Indian Ocean Sector) in January-March 2006. The survey is intended to produce a new estimate of B0 for this Division so that a revised precautionary catch limit can be established by CCAMLR. The planned survey will utilise a standardised design as adopted in previous B0 surveys in the CCAMLR Area and will use a similar methodology for collecting an analysing the data to that used on the CCAMLR2000 survey. The survey will be conducted from a single ship and will consist of 15 parallel transects between 30° and 80°E. The survey design is presented to WG-EMM for their comment so that any suggestions can be incorporated into the final design which will be presented to the Working Group in 2005.
