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.
