Quota hopping

Under the Common Fisheries Policy (CFP), fishing companies from one EU member country may try to establish themselves in another country’s fishing waters and therefore under its quota.
This is permitted because of the EU rules on the freedom of establishment. However, the EU Court has demanded that, to preserve the concept of genuine member state quotas, there should be some real connection between the fishermen in question, their boats, and the flag of the country they decide to fish under.
