The paper presents the results of biomass estimates of commercial fishes in the South Georgia region made by "swept area" method on the basis of catch statistics of a B-22 Polish trawler in the 1980/1981 season. Total biomass was estimated on about 11 x 104 t.

The material obtained between 1977 and 1979 has allowed to compare body length, age and sex of South Georgia fish caught in the region of South Georgia Island. The growth rate of body length and weight of individuals have been determined. According to results the South Georgia icefish at the time of investigations did not form a homogenous, stable stock in the region of South Georgia Island.
