    Résumé

    In January-March 1996 a hydroacoustic survey for Antarctic krill was conducted in CCAMLR Division 58.4.1 for the purposes of estimating overall biomass (B0). The krill biomass in the area surveyed (873,000 km2) was estimated to be 6.67 million tonnes with a CV of 27%. Krill were more abundant in the west of the survey area 800-1200E than in the 120°-150°E region. The majority of the krill detected were found in the top 80 metres of the water column.
