The abundance of the 1991-1994-year classes of north-east Arctic cod and haddock at the age
of six month have been estimated on the basis of Norwegian acoustic data from the
International 0-group fish survey in the Barents Sea and adjacent waters. These results have
been analysed in relation to the abundance of the respective year classes at ages 1-3, computed
by VPA with the XSA tuning procedure based on catch-at-age data including catch and
cannibalism/-predation by cod. This study indicates a reasonable agreement of the 0-group
fish abundance and the abundance of age group 1-3 in the pre-recruit phase.
