    Abstract

    The proportional krill recruitment index is updated from 2002 to present using data from the US AMLR surveys around Elephant Island, Antarctica. Proportional recruitment indices were derived from the CMIX procedure, and were also derived as a proportion of the <30 mm length class for day and night samples. All indices showed that high recruitment (R1) occurred in 2003 and in 2008, with low recruitment occurring during the intervening years. Significant differences in the proportional recruitment indices occurred between legs within years indicative of the changing pattern of krill within the Elephant Island region.
