Summary: Seven surveys were carried out during late June and July covering most of the continental shelf north of
54°N in the North Sea and lreland to the west of Scotland to a northern limit of 62°N. The eastern edge
of the survey area is bounded by the Norwegian and Danish coasts, and to the west by the Shelf edge
between 200 and 400 m depth. The surveys are reported individually, and a combined report has been
prepared from the data from all seven surveys. The combined survey results provide spatial distributions
of herring abundance by number and biomass at age by stat rectangle.
