Moult and growth in euphausiids.

Abstract

Laboratory growth rates in adolescent Antarctic krill Euphausia superba were similar to calculated hypothetical values. Reduction in body length during winter is not common to euphausiids; it was not found to occur in Meganyctiphanes norvegica which continues to moult in winter. Euphausiid growth can be monitored by moult-staging. Simultaneous moulting is a feature of E. superba in swarms.-from Author
