Towards a new method for age determination in Antarctic krill, and evidence that krill shrink under natural conditions
Abstract: Laboratory studies have shown that Antarctic krill Euphausia superba shrink if ... maintained in conditions of low food availability. Recent studies have also demonstrated that E. superba ... individuals may be shrinking in the field during winter. If krill shrink during the winter, conclusions ... reached by length-frequency analysis may be unreliable. In this study, the correlation between the body ...
