Abstract
Acoustic surveys targeting blue whiting (Micromesistius poutassou) spawning and post spawning aggregations in the north east Atlantic have been carried out by the Institute of Marine Research (IMR) Norway since the early 1970s.
The 2018 survey was part of an international collaborative survey using the vessels RV Celtic Explorer (Ireland), RV Tridens (Netherlands), FV Kings Bay (Norway) and the RV Magnus Heinason (Faroes). The total combined area coverage extended from the Faroe Islands in the north (62° N) to south of Ireland (51° N), with east -west extension from 1°-18° W. To the south of 51°N the Spanish research vessel the RV Miguel Oliver conducted a survey, complimentary to, but separate to the IBWSS survey, as part of their annual PELACUS survey program.
International survey participants met shortly after the survey to present data and produce a combined relative abundance stock estimate and report. The combined survey report is presented annually at the WGIPS meeting held in January. The information presented here relates specifically to the Irish survey unless otherwise stated.
