# Commission Decision of 18 December 2009 adopting a multiannual Community programme for the collection, management and use of data in the fisheries sector for the period 2011-2013 (notified under document C(2009) 10121) (2010/93/EU), Appendix VIII

Extent: E+W+S+N.I.

List of transversal variables with sampling specification
The disaggregation levels refer to appendix V (NB: the reference for metier or fishing activity is the level 6 of the Appendix IV (1-5)).
As defined in Regulation (EC) No 26/2004.
Some adjustments could be proposed by Regional Coordination Meetings.
For some variables, the disaggregation level of A is enough because Σ i A ij = B i … and Σ j A ij = C j (example: Hours fished), for others, Σ i A ij ≠ B i … and Σ j A ij ≠ C j (for example Fishing days, where two or more metiers can be practised during the same fishing day and accounted more than once).
If it is not possible to directly allocate landings from one trip into metiers, then this allocation should be based on rules agreed by STECF.
If possible, price data should be collected at the level A1 (see Appendix V) in order to calculate immediately the value of landings at this same level.
