Abstract

The moult-staging technique for euphausiids developed by Buchholz was examined experimentally to obtain estimates of the relative duration of each of the constituent stages. The method entailed removing uropods from indiviually maintainedEuphausia superba Dana on the day of moulting and for each day post-moult, and examining them microscopically to determine the moult stage. The krill were kept alive following uropod removal until the next moult so that the stage observed in the excised uropod could be referenced to both ends of the moult cycle for each individual examined. The proportion of the moult cycle occupied by each stage at 0°C was thereby calculated.
