Note on relationship between the Antarctic krill and annual variation of ice edge during 1979 to 1992
Abstract: During 1979 to 1991, relationship between the size of Antarctic krill and the extent of the sea ice in the sea area around the South Shetland Islands are described. Mean size of krill near the coastal zone appeared to be small in summer season just after a strong ice extent had occurred.

Note on maturity of krill in relation to interannual fluctuations of food environment in the seas around the South Shetland Islands
Abstract: Relationship between food environment and maturity of krill around the South Shetland Islands is discussed. Data during 91/92 austral summer shows that when chlorophyll concentration in fraction larger than 2um was high, feeding activity of krill was also high in the natural environment.

Environmental gradients of the Antarctic krill (Euphausia superba Dana) in the whole of the Antarctic Ocean
Abstract: The implications between a regional and whole distribution of the Antarctic krill, Euphausia superba DANA, and its environmental gradients in the summer season were considered. In order to find out the relationship between the geographical distribution of E. superba and its

Winter gut contents of the Antarctic krill (Euphausia superba Dana) collected in the South Georgia area
Abstract: Foregut contents of the Antarctic krill Euphausia superba Dana which were collected in the South Georgia area in austral winter, 12 July ~ 4 August 1992 were observed. A total of 130 individuals (adults: 78, subadults: 49, juveniles: 3) which were caught by krill trawling from various

Krill distribution and biomass variability within Subarea 48.3 in June 1991
Abstract: Temporal and spatial variability of krill distribution characteristics was investigated in an 8 x 6 mile micropolygon, where eight consecutive hydroacoustic surveys were carried out. Krill aggregations occurred a s fields of small swarms whose spatial distribution characteristics (size

Growth of krill around the South Orkney Islands in 1989/90
Abstract: 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

On problem of natural subdividing of Antarctic krill’s geographic area (an application to the monitoring of fishing)
Abstract: The possibilities of natural regionisation of antarctic krill's geographic area with emphasis on fisheries regions distribution are considered on the base of consisting data of spatial structure of krill's geographic area. More then 43% of regions, where usually present
