In order to ensure compliance with the rules of the common fisheries policy, a Community system is hereby established including in particular provisions for the technical monitoring of: conservation and resource management, structural measures, measure concerning the common organization of the market, as well as certain provisions relating to the effectiveness of sanctions to be applied in cases where the above-mentioned measures are not observed.

This Regulation shall apply without prejudice to any national control measures that go beyond its minimum requirements, provided that they comply with Community law and are in conformity with the common fisheries policy. The national measures referred to in the first subparagraph shall be communicated to the Commission.
