| 摘 要： | 利用1997-2008年南极磷虾产量及各月南极海冰面积数据，分析南极磷虾产量的时空分布，以及海冰对南极磷虾资源丰度的影响。结果表明，近年来南极磷虾年平均产量在11万t左右，主要来自48渔区，渔汛期为3—7月。但不同渔区（48．1区、48．2区和48．3区）在不同年份和季节，其产量和CPUE均有明显差异。分析认为，48区...

| Abstract: | Antarctic krill (Euphausua superba) is not only an important fishery target in the southern ocean, but also an important species of the southern ocean ecology. So, studying the effects of oceanic environment on the abundance of krill is vital. The study was to analyze the spatio-temporal distribution of krill catch and influence of sea ice on abundance of Antarctic krill using the global krill catch data from 1997 to 2008 and the corresponding monthly sea-ice extent in the Antarctic Ocean. The results sugge... |
