| 摘 要： | 关于冬季南极磷虾群昼夜垂直移动方面的研究可为探索其渔场形成机制提供基础数据,并为其越冬策略研究提供参考。基于2013年冬季南乔治亚岛南极磷虾渔业调查期间收集的相关数据,对冬季南乔治亚岛南极磷虾群昼夜垂直移动进行了研究。结果发现,磷虾群平均深度维持在表层以下100～300 m,磷虾群最深出现在日升时分,而最浅则出现在夜间时分;7—9月,随时间的推移,磷虾群所处水层呈加深趋势。夜间、白天和黄昏时段磷虾群平均深度呈现较为明显的月份差异。白天磷虾群多集中在较深水层,夜间会上浮到较浅水层。

| Abstract: | The knowledge of diel vertical migration (DVM) of Antarctic krill aggregation (AKA) in the winter season will provide basic data to study the forming mechanism of fishing ground and provide the reference to study the overwintering strategy.Based on the data collected by the fishery survey on Antarctic krill population in the South Georgia Island during the austral winter 2013,the present study analyzes the DVM of AKA in the South Georgia Island.The results show average depth of AKA maintains 100 m to 300 m under sea surface,and the deepest and shallowest depths the of AKA occur at sunrise and night respectively.The average depth of AKA is deepening from July to September.The average depths of AKA show a significant monthly difference at night,in the day and at dusk.AKA often occurs in the deeper layer in the day and stays at surface at night. |
