French fishermen will be SLOT XO allowed to work in Jersey waters without meeting new Brexit permit conditions for another three months.
Ministers agreed to extend the temporary policy while they finalised a new trade agreement.
It was due to expire but after a request from the EU, Jersey has agreed to extend it to the end of September.
Royal Navy vessels were sent to patrol waters around Jersey when the row escalated in May.
Jersey authorities have asked for confirmation the extension will also apply to local boats in EU waters.
In recent weeks Jersey, the UK, France and EU officials have been in discussions over the implementation of a new Trade and Cooperation Agreement (TCA).
The TCA requires evidence of the "extent and nature" of previous fishing activity to be demonstrated in order for access to be granted.
The EU requested an extension to the transitional arrangements, which had been due to come to an end on 30 June.
The Government of Jersey agreed to the request, which relates to vessels which the EU has submitted applications on behalf of, allowing more time for further track record evidence to be submitted and analysed.
