Introduction: The results from the International Young Fish survey become
available in successive steps. During the survey the numbers of
1-group fish, based on fish below a certain length, are exchanged
between the participating research vessels. Immediately after the
survey the length compositions of the seven standard species are
sent to ICES (in IYFS exchange format), to be used by the different
assessment working groups, together with all age-length keys
which are available by then. Final data, including length compositions
for all species and age-length data, should be submitted
to ICES before 15 April. These data are then checked and stored
in the ICES IYFS data base, in order to be able to run the final
analysis in time for the May meeting of ACFM. This report is
based on the analysis done in May 1990.
