ICES Advice Last Year ICES Advice Last Year

The estimated SSB for 2008 has been revised upwards by 40% and the estimated fishing mortality in 2007 has been revised downwards by 13%. Around 40% of the change in SSB is due to the greater reliance this year on spawning ground survey results (relaxation of the constraint on survey CV), and the remainder due to the addition of recent data. This Year ICES Advice Compared to last year, the SSB for 2009 is

estimated to be about 42% lower and the fishing mortality in 2008 to be about 65% higher.

Extract ICES Advice 2010

Biology Blue whiting is widely distributed in the eastern part of the North Atlantic with the highest concentrations along the edge of the continental shelf between 300 and 600 m. Most of the spawning takes place along the shelf edge and banks west of the British Isles. Juveniles are abundant in many areas, with the main nursery area believed to be the Norwegian Sea. Recent work on stock identification suggests that there is likely to be more than one single stock in the Northeast Atlantic.

  • Calculation MSY in transition

Calculation MSY in transition

“For stocks for which no long-term plans have yet been proposed, it would be appropriate to move towards MSY by reducing fishing mortality in equal steps from the 2011 fishing year until the 2014 fishing year to Fmsy, and exploiting stocks at Fmsy in 2015 and thereafter. Starting in 2011, this means four equal steps.”
