1. Green krill, the indicator of micro- and nano-size phytoplankton availability to krill

   Abstract:  Size fractionated chlorophyll-a concentrations of surface seawater was measured (pico-, nano-, and micro-size fractions) during commercial krill operations in the waters north of the South Shetland Islands from late December, 1991 to mid-February, 1992. The proportion of green krill had

2. Status of the Polish FIBEX acoustic data from the west Atlantic

   Abstract:  Acoustic data from the Polish FIBEX survey in the West Atlantic were examined to check the consistency of krill abundance estimates against the results of the other FIBEX survey vessels. The results indicated that there was a high level of consistency between the results from the Polish

3. Pursuit and polynyas in the Ross Sea, Antarctica

   Abstract:  Polynyas accelerate oceanic and atmospheric processes. We additionally think polynyas influence biological activity. We pursued daily transition of polynyas in the Ross Sea, Antarctica from 1978 through 1994 using images of sea ice concentrations by the satellite microwave observations.

4. Krill distribution in the western Atlantic sector of the Southern Ocean during 1983/84, 1984/85 and 1987/88 on the basis of the Soviet mesoscale surveys with Isaacs Kidd midwater trawl

   Abstract:  In the paper the results of the investigations on three mesoscale surveys covering wide area of krill between Antarctic Peninsula and South Georgia Island are considered. Surveys including from 158 to 202 stations were carried out by Soviet research vessels in summer-autumn periods of

5. Proportional recruitment indices of Antarctic krill from Japanese fisheries data in Subareas 48.1, 48.2 and 48.3 during 1980 through 1997

   Abstract:  Proportional recruitments (R1 and R2) were calculated for Subareas 48.1, 48.2 and 48.3 from logbook data of Japanese commercial krill fisheries during 1980 to 1997. Inter-annual patterns of R1 and R2 in Subarea 48.1 generally showed similar trends to Siegel et al. (1 998)'s values

6. Studies on zooplankton with special reference to krill from the Indian Ocean sector of the Southern Ocean

   Abstract:  Distribution, abundance and species composition of zooplankton collected during the First Indian Antarctic Krill Expedition were studied. Zooplankton biomass values ranged fiom 9.79 to 303.62m1./100m-3 (x=142.14±77.02). High standing stock values were recorded in the study area where

7. Hydroacoustic assessment of krill in Area 58 of the Indian Ocean sector of the Antarctic region

   Abstract:  On the basis of acoustically registered krill swarms along a 1097 nm transect in the area 58 of Indian Ocean Sector of Antarctic region, the biomass density of krill, their spatial and depth distribution are presented. The mean density of krill biomass between 60°00'S and 61°00'

8. Investigations on midwater trawling for krill (Euphausia superba) in the Southern Ocean

   Abstract:  Results of harvesting operations for Antarctic krill (Euphausia superba) in Fishing Area 58 in the Indian Ocean Sector of Southern Ocean, during the First Indian Antarctic Krill Expedition (27 December 1995- 10 March 1996) on board FORV Sagar Sampada are summarised in this paper. 18

9. A model at the level of the foraging trip for the indirect effects of krill (Euphausia superba) fisheries on krill predators

   Abstract:  We present a model at the level of the foraging trip for the effects of a fishery on krill (Euphausia superba) predators, using the Adelie penguin (Pygoscelis adeliae) as a model organism. The model involves: (i) the description of the biomass and spatial distribution of krill; (ii) the
