media caption They want talks : The BBC s Robert Hall is at Jersey s St Helier port
Jersey officials are meeting French fishermen, who have been protesting over their post-Brexit rights, in an attempt to resolve the dispute.
Two Royal Navy ships and two French vessels are patrolling near Jersey while about 60 French and Jersey boats are at the island s St Helier port.
French fishermen say their rights are unfairly restricted by licences issued by the island under a new system.
No 10 said the PM has been in contact with Jersey officials over the row.
HMS Severn, which has previously been used to shadow Russian navy warships off the English coast, can be seen from the port, sitting off about a mile from the French boats. HMS Tamar is nearby and both ships are maintaining a presence and not making any effort to intervene.

The UK is sending two Royal Navy patrol vessels to monitor a protest in waters around Jersey s main port amid a fishing rights row with France.
PM Boris Johnson said any blockade would be completely unjustified as over 100 French fishing boats prepared to sail to the island on Thursday.
It follows a threat by France to cut off Jersey s electricity over new post-Brexit rules for French fishing boats.
No 10 said sending the Navy vessels was a precautionary measure .
HMS Severn is currently heading towards the waters off Jersey s port of St Helier. HMS Tamar will follow later.
