The credibility of the EU's Common Fisheries Policy (CFP) depends on an effective enforcement and application of the agreed rules. With the adoption of detailed rules to apply the EU Fisheries Control Regulation, the reform of the EU’s control and enforcement policy is now complete. The new system is made up of three pillars: the Control regulation1; the IUU Regulation to combat illegal, unreported and unregulated fishing2 (which applies to both EU and third-country vessels); and the Regulation on Fisheries Authorisations3 (which deals with the control of EU vessels fishing outside EU waters and of third country vessels fishing in EU waters). The new rules replace a system which proved to be complex, inefficient and expensive. They make the EU control and enforcement system up-to-date, more efficient and well adapted to the challenges of the 21st century. This is all the more relevant to guarantee the respect of the new set of rules that will emerge from the upcoming reform of the Common Fisheries Policy.
