1. Trawl survey of the Patagonian toothfish (Dissostichus eleginoides) resource off the Prince Edward Islands

   Abstract:  A bottom trawl survey was conducted in the northern half of the South African EEZ around the Prince Edward Islands in April 2001. Due to the paucity of bathymetric data, it was not possible to design a statistically rigid survey, consequently this first survey is regarded as a pilot

4. Uncertainty in acoustic surveys of Antarctic krill

   Abstract:  Studied were four primary sources of uncertainty in krill density estimates from acoustic surveys. The variance in system calibration with a standard sphere was evaluated in relation to sphere material and diameter, water temperature, and pulse length (Demer and Hewitt, 1992).

5. Preliminary results of stock estimation for D. mawsoni using CASAL in the research block 48.6_2

   Abstract:  A preliminal CASAL model was constructed for D. mawsoni at the research block 48.6_2. The model assumes that single sex and age structured model without considering IUU. Tag release data during 2012–2017 was used. Catch data during 2006–2017 was used as fishery data.  In the MPD, age and
