  8. WGBFAS 2009 HERRING IN SD 30 Short-term implications Outlook for 2010 Basis: F(2009) = Fsq= F(2006-2008) =0.147; SSB(2009) = 474.2; Landings (2009) = 72.4. Weights in ‘000 t. Shaded scenarios are not considered consistent with the precautionary approach. 1) SSB 2011 relative to SSB 2010. Recommendation Fishing below Fpa in 2010 correspond to landings of less than 109.600t
