The International Blue Whiting Spawning Stock is conducted yearly and provides the only fishery independent SSB estimate of this specie used in the assessment at the Working Group Widely Distributed Stocks (WGWIDE). Previously, the results were used by the ICES Blue Whiting Assessment Working Group. The survey north 51°30' started in the seventies and applies the echointegration method to estimate the blue whiting abundance.
