1. 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.

2. Estimates of primary production by ice algae and phytoplankton in the coastal ice-covered area near Syowa Station, Antarctica

   Abstract:  Annual primary production of ice algae and phytoplankton under fast ice near Syowa Station (69°00'S, 39°35'E), Antarctica, was estimated. Mean daily production in each month from February 1983 to January 1984 was calculated with a mathematical model based on measured parameters

3. 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

4. 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

5. Status of the FIBEX acoustic data from the west Atlantic

   Abstract:  Data from the FIBEX acoustic survey in the West Atlantic sector have been re-examined to check the consistency of krill abundance estimates derived from different survey vessels. There is a good level of consistency between the results from four of the vessels, Itzumi, Dr Eduardo L

6. 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

7. 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

8. 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

9. Factors influencing Antarctic krill distribution in the South Shetlands

   Abstract:  The influences of biological and physical factors in the environment upon krill (Euphausia superba) distribution were studies in the area north of South Shetland Islands during 1990/91 austral summer. Krill showed a distinct offshore-inshore heterogeneities in abundance and maturity
