Management Advice

Management considerations

The advice for 2009 is biennial and valid for 2009 and 2010 and is cited in the text table below (see ICES. 2008. Report of the ICES Advisory Committee, 2008. ICES Advice, 2008. Book 9. 345 pp.)

Spurdog (Squalus acanthias). All areas The only new information that is available for spurdog (Squalus acanthias) is landings data which does not give reason to change the advice from 2006. The advice for 2009 and 2010 is therefore the same as the advice given in 2006: “The stock is depleted and may be in danger of collapse. Targeted fisheries should not be permitted to continue, and by-catch in mixed fisheries should be reduced to the lowest possible level. The TAC should cover all areas where spurdog are caught in the northeast Atlantic and should be set at zero (...).”
