dc.description.abstractFour 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.no_NO
