International Blue Whiting Spawning Stock Survey (IBWSS) Spring 2022

Coordination of the survey was initiated at the meeting of the Working Group on International Pelagic Surveys (WGIPS) in January 2022 and continued by correspondence until the start of the survey. During the survey, effort was refined and adjusted by the survey coordinator (Norway) using real time observations. Survey design was based on methods described in ICES Manual for International Pelagic Surveys (ICES, 2015). Overall, weather conditions were exceptional compared to 2021, with calm seas prevailing, providing optimal conditions for acoustic recordings. The entire survey was completed in 15 days, well below 21-day target threshold (Figure 4). Area coverage was considered comprehensive in both core and peripheral areas, with all vessels completing the planned routes, with the exception of the RV Celtic Explorer (Ireland) which returned to port 8 days early.
