摘要：

Correlation between the body length and the diameter of the compound eyeof the Antarctic krill Euphausis sulfa was examined. From the samples collected inthe late summer, it shows that there is an apparent exponential relationship betweeneye diameter and the body length. From the laboratory population, it seems that whenthe krill shrink, the diameter of the compound eye does not decrease. It is more reliableto use the eye diameter as krill growth index than they length. The ratio of the theylength to the diameter of the compound eye offers another method for detecting the effect of shrinking in natural populations of krill.

It is more reliableto use the eye diameter as krill growth index than they length. The ratio of the theylength to the diameter of the compound eye offers another method for detecting the effect of shrinking in natural populations of krill.
