    Abstract
    In spring 2007, 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 fourth 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 (Celtic Explorer: O’Donnell et al. 2007; Eros: Godø et al. 2007; M. Heinason: Jacobsen et al. 2007; Tridens: Ybema 2007). This report is based on a workshop held after the international survey in IJmuiden, 18-19/4/2007 where the data were analysed and the report written. Parts of the document were worked out through correspondence during the workshop and during a protracted period after the workshop.

      International Blue Whiting Spawning Stock Survey (IBWSS) Spring 2013

      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.
