    On the ground of materials collected by biologists-observers from October 1989 to June 1990 near the South Orkney Islands the growth of males and females are characterized according to size groups, distinguished using the probability paper. Seven size groups both for males and females were distiguished. The growth period for the males continued from October to April, and from October to February for the females. The increment for this period was the same for both sexes and had about 8–9 mm in length. The males’ one day increments were 0.046–0.076, and for the females – 0.065–0.074 mm. It is supposed that krill don’t reach the age of 5 years.
