Blue Whiting Acoustic Survey Cruise Report, March 22 - April 01, 2015O'Donnell, C.; Nolan, C.; Johnston, G.; Keogh, N.; van der Knaap, I.; Borawska, A.; O’Donovan, M. (Marine Institute, 2015)Acoustic surveys on blue whiting (Micromesistius poutassou) spawning aggregations in the north east Atlantic have been carried out by the Institute of Marine Research (IMR) Norway since the early 1970s. The 2015 survey was part of an international collaborative survey using the vessels RV Celtic Explorer (Ireland), FV Fridtjof Nansen (Russia), RV Tridens (Netherlands) 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 4°-18° W. International survey participants meet 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 component.
