中文摘要：
本文利用中国大型拖网渔船在船上实时分析获得的南设得兰群岛东部海域捕获南极大磷虾活体脂质含量数据,分析比较了不同时间段南极大磷虾磷脂营养成分变化特征。结果表明,南极大磷虾磷脂含量丰富,平均含量达到了磷虾干重的5.4%,同时3个时间段南极大磷虾磷脂含量存在着显著性差异,1月下旬的南极大磷虾磷脂的含量最高,显著高于1月上旬和12月下旬。南极大磷虾丰富的磷脂及其磷脂含量的时间差异可为南极大磷虾今后的可持续商业捕捞和开发利用提供参考依据。
英文摘要：
Using the data of fresh Antarctic krill （Euphausia superba） collected from the eastern waters of South Shetland Islands by fishery observers on board, the current research analyzed the phospholipids （PL） content variations of the krill. The average content of PL was found to be 5.4% based on dry matter. The significant highest content of PL was found in late January, followed by early January and late December. The results obtained from this research showed the abundance of PL and the variations of PL in Antarctic krill as well. These findings may provide reasonable references for sustainable commercial harvesting and exploiting of this resource in the future.
