DISTRIBUTION AND ABUNDANCE OF EGGS AND LARVAE OF ANTARCTIC KRILL (ENPHAUSUA SUPERBADANA)IN ANTARCTIC PENINSULA AREA

         

摘要

During the First Chinese Antarctic Expedition zooplankton samples were collected at each of the oceanography stations in the waters around South Sheltland Islands (S. S. Is.) and in the northern part of the Bellinshausen Sea from 20 January to 12 February, 1985 by vertical tows of an 80 cm diameter conical net from 200 m to surface. Two deep tows with a closing net. were performed in slope water north of S.S. Is, and in the basin of Bransfield Strait. Eggs and larvae of Euphatisia superba Dana in zooplankton samples were identified and counted.There were four records of eggs from 27 stations. Most catches were of small number and restricted to within the nearshore area south of S.S Is.The largest number (1500/1000 cubic meters )was found in the outer side of Smith Island.No Nauplius was found . The earliest stage we found was Metanauplius , in two deep tows. The distribution of Calyptopis MI and Furcili I-III were quite similar. They were found mainly in three areas: 1 ) nearshore water along the south
