According to Article 43(3) of the Treaty, the Council, on a proposal from the Commission, is to adopt measures on the fixing of prices.

Council Regulation (EC) No 104/2000 of 17 December 1999 on the common organisation of the markets in fishery and aquaculture products1 requires that guide prices and Union producer prices for each fishing year be fixed in order to determine price levels for intervention on the market for certain fisheries products.

It is incumbent upon the Council to fix the guide prices for each of the products and groups of products listed in Annexes I and II to Regulation (EC) No 104/2000, and the Union producer prices for the products listed in Annex III to that Regulation.

On the basis of the data currently available on the prices for the products concerned and the criteria referred to in Article 18(2) of Regulation (EC) No 104/2000, the guide prices should be increased, maintained or reduced for the 2011 fishing year depending on the species.

It is appropriate to establish the Union producer price for one of the products listed in Annex III to Regulation (EC) No 104/2000 and calculate the Union producer prices for the others by means of the conversion factors established by Commission Regulation (EC) No 802/2006 of 30 May 2006 fixing the conversion factors applicable to fish of the genera Thunnus and Euthynnus2.

On the basis of the criteria laid down in the first and second indents of Article 18(2) and in Article 26(1) of Regulation (EC) No 104/2000, the Union producer price for the 2011 fishing year should be adjusted,
