ABSTRACT:  

Two processes influence recruitment at the end of the first year of life of
Euphausia superba, the Antarctic krill; 1) reproductive output of the spawning
population the previous spring and summer, and 2) survival of the larvae and
juveniles during their first two critical periods (first feeding, survival
over winter) (Ross and Quetin, 1991).  Seasonal sea ice characteristics were
used as a proxy for food availability, i.e. a predictor of the
'match/mismatch' between adult and larval food requirements and food
availability in spring and winter.
