Senator Philip Ozouf said that the exclusion of Jersey fishermen was creating diplomatic waves beyond the islands’s ports.
And that, he said, could not be allowed to continue.
His comments follow reports in November that a meeting between the islands’s senior politicians became acrimonious when the subject surfaced.
The talks were held to try to resolve a long-running dispute over Guernsey’s insistence that Jersey and UK commercial fishermen have to have a licence to fish within three to 12 miles of the Guernsey coast.
The talks centre on a proposal to grant licences to 28 Jersey boats.
