Two vessels, the Argos Helena (UK) and the San Aspiring (New Zealand), fished around the South Sandwich Islands (Subarea 48.4) in 2006 following one vessel, the Argos Helena, fishing in 2005. During this time animals were tagged in order to continue a mark-recapture programme started in 2005 to assess the toothfish population. We present an analysis of the catch and tagging data and a proposal for continuing research in this area in 2007.
