French fishermen gathered in Normandy this weekend to protest against the new post-Brexit licencing rules.
They are unhappy about the need for tracking data that they say smaller boats cannot provide.
French MP, Bertrand Sorre, says fishermen are being asked to provide a history of fishing in Jersey waters - however he says some smaller boats are unable to do this as they are not fitted with GPS trackers.
There is also concern that some fishermen will not know whether they can carry on working if paperwork is not complete by the end of the month.
