It is about Jersey waters,
'It is claimed that the UK government is using red tape to limit the operations of French fishing vessels, in contravention of the trade and cooperation agreement struck with the EU on Christmas Eve. The UK government denies the claim, saying Jersey alone is responsible for the management of its waters.
On Friday, 41 ships equipped with Vessel Monitoring System (VMS) technology, which allows ships to be located, were authorised to fish in waters off Jersey, which is a self-governing dependency.
Girardin told the French parliament that the list of approved ships had come with new rules “which were not arranged or discussed [with France], and which we were not notified about”.'
