1. Yet further krill yield computations

   Abstract:  Preliminary computations are carried out for the krill yield model of Butterworth et al. (1993), adjusted as requested by the fifth meeting of WG-KRILL. This involves modifying the input distributions for the lengths at recruitment and maturity, natural mortality and the extent of

2. Further calculations of the effects of krill fishing on predators

   Abstract:  Earlier initial modelling attempts by the authors are extended to consider the situation where predator survival rates depend on other factors in addition to krill biomass. This is achieved by making the survival rates depend instead on krill "availability", where there is a

3. Fishes caught along with the Antarctic krill in the vicinity of the South Shetland Islands during the austral summer months of 1994

   Abstract:  Observations on abundance of by-catch fishes were made during the austral summer months of 1994 (from January 12 to February 18) on board F/V Niitaka Maru in the north of the South Shetland Islands. Among 99 net hauls examined, a total of 77 specimens of fishes belonging to 13 species

4. Numerical model of ecosystem including Euphausia superba Dana as a key species in circumpolar region

   Abstract:  On the processes to investigate a proper model for understanding the processes that govern the biochemical cycle in Antarctic Ocean, we made a research plan as follows: (1) to develop an OGCM (Ocean General Circulation Model) (2) to develop a one dimensional ecosystem model that can be

6. CPUEs and body length of Antarctic krill during 1992/93 season in the fishing grounds north of Livingston Island

   Abstract:  This paper summaries Japanese krill catch data during austral summer in 1992/93 season. A main fishing ground was persistently formed north of the Livingston Island. CPUEs show the highest values at the height of summer (late February- late March).Krill with modal length of 41-45mm were

7. Hydrographic flux in Statistical Area 88 of ccamlr in the Pacific sector of the Southern Ocean

   Abstract:  This document submits the basic information on the hydrographic flux in Statistical Area 88 of CCAMLR in the Pacific sector. Those are surface geostrophic flow in the whole of the Statistical Area 88 and vertical distributions of geostrophic velocity and temperature along 90°W, 120°W,

8. Change of sex ratio of krill (Euphausia superba) from austral early summer to midsummer in 1983/84 in the vicinity of Prydz Bay, Antarctica

   Abstract:  In this present report the change of the Antarctic krill distribution pattern from December 1983 to January/February 1984 in the vicinity of Prydz Bay was analysed. The results showed the remarkable change of sex ratio and coefficient of fatness between the early summer and the midsummer

10. Biological acoustic survey in the marginal ice edge zone of the Bellingshausen Sea

    Abstract:  An acoustic survey at 38 and 120 kHz was carried out from RRS Discovery in the Bellingshausen Sea from 23 November to 7 December 1992 as part of the UK Joint Global Ocean Flux Study (JGOFS) Southern Ocean investigations (TuRNER and OWENS, 1995). A total of 285 targets were identified and
