Abstract
During the period 22 May to 17 July the spawning area of North Sea

mackerel was investigated by research vessels from Scotland, the

Netherlands, Denmark and Norway. Based on the 629 plankton samples and

temperature observations obtained during this period the egg production

and spawning stock size were estimated.
