Based on advice from the International Council for the Exploration of the Sea (ICES) to end fishing for deepwater sharks, the European Union Fisheries Council established a Total Allowable Catch (TAC) for deepwater sharks in 2007. This TAC was gradually reduced and in 2010 it was set at zero. In 2011, the allowable bycatch was reduced from 10% to 3% of the 2009 TAC and in 2012 it was further reduced to zero.
