在一个研究水族箱中对南极磷虾的成熟周期进行了长期研究。在不同的温度和食物条件下，对南极磷虾进行了8个月的单独饲养和分组饲养，观察了南极磷虾雌性成熟期和蜕皮间期的演替。在所有情况下，退化和外部性特征的再成熟进行了观察，但有实验条件之间的周期和蜕皮间期的长度的差异。基于这些结果，并从以前的研究中获得的信息，我们提出了一个概念模型，描述磷虾生理的季节性周期，为未来的研究提供了一个框架，并强调其链接到环境条件的时间的重要性。
A long-term study on the maturity cycle of Antarctic krill was conducted in a research aquarium. Antarctic krill were either kept individually or in groups for 8 months under different temperature and food conditions, and the succession of female maturity stages and intermoult periods were observed. In all cases regression and re-maturation of external sexual characteristics were observed, but there were differences in length of the cycle and intermoult periods between the experimental conditions. Based on these results, and information available from previous studies, we suggest a conceptual model describing seasonal cycle of krill physiology which provides a framework for future studies and highlight the importance of its link to the timings of the environmental conditions.
