On the grounds of materials collected by biologists-02servers from October 1989 to June 1990 near South Orkney Islands the growth of males and females are characterized according to size groups, distinguished using the probability paper. Six size groups both for males and females were distinguished. Period of the intensive growth of the males continued from December to April, and for the females from November to February. The males increased their size for different size groups by 7-10, females by 8-10 mm. The rate of growth for the males was higher among the small specimens and vice versa for the females. Growth rates are similar to those observed in 1984-1985 in the South Orkneys and in the Admiralty Bay (King George Island).
