The krill maturity cycle: a conceptual description of the seasonal cycle in Antarctic krill
Abstract: A long term study on the maturity cycle of Antarctic krill was conducted in a research ... 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 ...
