The protest comes as fishing crews say have stopped them from landing their catch in the harbour.
11 years ago ,work began on the new harbour, which prevented local fishing vessels accessing to their moorings, but they say commitments were given that that berths would again be provided, once the new harbour opened.
Local fishermen say subsequent harbour by-laws drafted by Wicklow County Council officials have effectively excluded fishing boats, by imposing excessively high fees.
At present, they must berth and operate from as far away as Dun Laoghaire.
