At the 1978 statutory meeting, the Council adopted a resolution put forward by the Pelagic fish committee VIa in 1979. The guidelines for the survey were set out in the report of the Herring assessment working group (CM 1978/H:67 revised), and the objectives of the survey were to estimate the biomass of adult herring north of 57°N in subdivision IVa W and division VIa. The recommended timing of the survey was July.
