      Coordination of the survey was initiated in the meeting of the Working Group on International Pelagic Surveys (WGIPS) and continued by correspondence until the start of the survey. During the survey, updates on vessel positions and trawl activities were collated by the survey coordinator and distributed to the participants twice daily. Norway did not participate in the survey this year. The survey design used and described in ICES (2012) allowed for a flexible setup of transects and good coverage of the spawning aggregations. Due to acceptable - good weather conditions throughout the survey period, the survey resulted in a high quality coverage of the stock. Transects of all vessels were consistent in spatial coverage and timing, delivering full coverage of the respective distribution areas within 19 days.

During the survey, updates on vessel positions and trawl activities were collated by the survey coordinator and distributed to the participants twice daily. The survey design used and described in ICES (2014) allowed for a flexible setup of transects and good coverage of the spawning aggregations. Considering weather conditions were by no means optimal during the survey period, good quality coverage of the stock was achieved. Transects of all vessels were consistent in spatial coverage and timing, delivering full coverage of the respective distribution areas within 14 days.

During the survey, updates on vessel positions and trawl activities were collated by the survey coordinator and distributed to the participants twice daily. The survey design used and described in ICES (2015) allowed for a flexible setup of transects and good coverage of the spawning aggregations. Overall weather conditions were good during the survey with a total of 3 days weather down time recorded. Transects undertaken by all vessels were consistent in spatial coverage and timing, delivering full coverage of the respective distribution areas within 23 days.

      Coordination of the survey was initiated in the meeting of the Working Group on International Pelagic Surveys (WGIPS) and continued by correspondence until the start of the survey. During the survey effort was refined and adjusted by the coordinator based on real time observations. The survey design applied followed methods described in ICES Survey design Manual (2015) and allowed for a flexible transect design and comprehensive coverage of the spawning aggregations. Overall weather conditions were mixed with periods of poor and good weather. All vessels, with the exception of Kings Bay experienced some downtime due to conditions with the Faroes experiencing the most prolonged period of bad weather at the end of the survey period. The entire survey was undertaken within 20 days and below the 21 day target threshold. The bulk of the survey was temporally consistent with the exception of one transect in the southern Rockall Trough.

      In spring 2006, five research vessels representing the Faroe Islands, Ireland, the Netherlands, Norway and Russia surveyed the spawning grounds of blue whiting west of the British Isles. International co-operation allows for wider and more synoptic coverage of the stock and more rational utilisation of resources than uncoordinated national surveys. The survey was the second coordinated international blue whiting spawning stock survey since mid-1990s. The primary purpose of the survey was to obtain estimates of blue whiting stock abundance in the main spawning grounds using acoustic methods as well as to collect hydrographic information. Results of all the surveys are also presented in national reports (Atlantniro: Shnar et al. 2006; Celtic Explorer: Mullins et al. 2006; G. O. Sars: Heino et al. 2006; M. Heinason: Jacobsen et al. 2006; Tridens: Ybema et al. 2006). This report is based on a workshop held after the international survey in Tórshavn, 20–21/4/2006, where the data were analysed and the report written. Parts of the document were worked out through correspondence during and after the workshop.
