  "scientific_advice" : [ "Single-stock exploitation boundaries ICES advises that total catches in 2010 should be between 527 000 tonnes and 572 000 tonnes. Exploitation boundaries in relation to existing management plans The precautionary management plan described above for Northeast Atlantic mackerel (F between 0.20 and 0.22) implies catches between 527000t and 572000 t in 2010. The SSB is expected to remain stable in 2011 for a catch in this range. Exploitation boundaries in relation to precautionary considerations ICES advises that the existing measures to protect the North Sea spawning component remain in place. These are: There should be no fishing for mackerel in Divisions IIIa and IVb,c at any time of the year; There should be no fishing for mackerel in Division IVa during the period 15 February–31 July; The 30 cm minimum landing size at present in force in Subarea IV should be maintained.
