1. 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

2. 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

3. 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

4. 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

6. Further computations of the consequences of setting the annual krill catch limit to a fixed fraction of the estimate of krill biomass from a survey

   Abstract:  The results of Butterworth et al. (1992) relating potential krill yield to a pre-exploitation survey estimate of kril1 biomass are extended to incorporate most of the amendments specified by the Third and Fourth Meetings of Working Group on Krill. The most important of these extensions

7. Possible effects of different levels of fishing on krill on predators - some initial modelling attempts

   Abstract:  An initial attempt is made to develop the model1ing framework suggested by the Joint Meeting of the CCAMLR's WG-Kril1 and WG-CEMP in 1992 to address this issue. First. estimates are made of the parameters of predator survival rates as functions of krill abundance, by considering a

8. Natural mortality rates of the Antarctic krill Euphausia superba Dana in the Indian sector of the Southern Ocean

   Abstract:  Data on the size and age composition of Euphausia superba were collected in the Cooperation and Cosmonaut Seas from 1985 to 1990. The coefficients of instantaneous natural mortality of E.superba in the Indian sector of the Southern Ocean were calculated according to Alverson-Carney’s

9. Fishes caught along with the Antarctic krill in the vicinity of the South Georgia Island during the austral winter months of 1992

   Abstract:  Observations on abundance of by-catch fishes were made during the austral winter months of 1992 (from July 9 to August 3) on board F/V No.3 and No.5 Chiyo Maru in the vicinity of the South Georgia Island. Among 74 net hauls examined, a total of 66 specimens of fishes belonging to 3
