1. Preliminary study on reproduction in Champsocephalus gunnari from Subarea 48.3, Dr Eduardo Holmberg survey, February/March 1994

   Abstract:  A preliminary histological analysis on the ovarian development in Champsocephalus gunnari was carried out. Six stages of oocytary development were identified and are similar to those described for other species. A gonad maturation scale was elaborated and adapted to the macroscopic scale

2. 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

4. 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

8. Possible approach to krill movement estimation by hydroacoustic observations

   Abstract:  Method of estimation of krill drift velocity in water current,using repeated acoustic transects on rectangular polygon is discribed.Dimensions of polygon and frequency of acoustic observations have to be determined with taking into account distribution patterns of krill,its patchiness,
