CPUE, net towing depth and body length of krill during the winter operation of Japanese krill fishery around South Georgia
were calculated. The range of CPUE values in 1991 season (poor year of krill) was comparable to the ... from net towing depth. Net tow depth data implied that overall krill distribution in the the winter ... season might be deeper than the summer season. Interannual variability of vertical distribution was also ... suggeted. Length frequency distribution implied the evidence of strong krill influx from the Antarctic ...
