    55EwE users can create a set of biomass groups representing life history stages or stanzas for species that have complex trophic ontogeny.  Mortality rates (''M0'', predation, fishing) and diet composition are assumed to be similar for individuals within each stanza (e.g. larvae having high mortality and feed on zooplankton, juveniles having lower mortality and feed on benthic insects, adults having still lower mortality and feed on fish).  Users of this feature must enter baseline estimates of total mortality rate ''Z'' and diet composition for each stanza, then biomass, ''Q/B'', and ''BA'' for one “leading” stanza only.
