Note that these figures include Autumn Spawners caught in the Skagerak/Kattegat, but exclude Spring Spawners (Western Baltic and local stocks) caught in the North Sea! The heading for recruitment in the respective ACFM-report erroneously states "Recruitment at age 0", which should read "...at 0 winter rings". This is, for North Sea Autumn Spawners, equivalent to age 1.
