Four herring acoustic surveys coordinated by ICES were carried
out by Scottish, Norwegian, Swedish and Danish research vessels
during the period 28 June to 9 August 1989.
The reports on the individual surveys, giving a short description
of the survey, and a presentation of the results, are collected
in this paper. The combined estimated spawning stock biomasses of
herring were 1.6 million tonnes autumn spawners and 255 000
tonnes of spring spawners. The combined results are discussed in
the paper.
