Krill biomass and density distribution in February–March 2002 in Subarea 48.3

Presented are the results of krill acoustic survey carried out by Russian RV Atlantida on the South Georgia shelf within the 500-m isobath. The survey was made during the period from February 14 to March 5, 2002. Average krill density in the survey area was estimated at 45.45 g/m2 and total biomass at 1,898,492 ton. The analysis of krill aggregation distribution was made for identification of potential fishing grounds. Also presented are the results of density assessment on potential fishing grounds and a map of their location. Location of potential fishing areas is still another evidence of the fact that no sustainable commercial aggregations are formed during critical period for animals feeding on krill in the area of the South Georgia western extremity where main feeding grounds serving their needs for food exist.
