1. The Portuguese authorities shall communicate to the Commission proposals for periodic lists, specifying the vessels which may fish at the same time, in conformity with Article 349 of the Act of Accession, at least 15 days before the date set for the entry into force of such lists. A separate list shall be forwarded for each type of fishing referred to in Article 2. In the case of vessels fishing for blue whiting and horse mackerel, the lists shall cover a period of one calendar month; in the case of vessels fishing for tuna, the lists shall cover a period of at least two calendar months. 2. The monthly periodic list of the vessels fishing for blue whiting and horse mackerel shall specify on a day-by-day basis the vessels authorized to fish at the same time; each vessel must appear on the list for at least six consecutive days. The Portuguese authorities shall take such administrative measures as are appropriate to ensure that the vessels referred to in the first subparagraph cannot leave the port from which they operate before the date corresponding to that fixed in the periodic list for the pursuit of fishing in the zone in question taking into account the usual transit time taken to reach the nearest geographical limits of the said zone. They shall also ensure that the vessels have re-entered the port from which they operate, in accordance with the corresponding transit time. In addition the Portuguese authorities shall cooperate with the competent authorities of the Member States concerned to ensure that movements of these same vessels sailing from a port of another Member State shall be in accordance with the terms and conditions authorizing the types of fishing as referred to in this Regulation. 3. Each of the periodic lists shall provide the following information on each vessel: - name and registration number of the vessel, - call sign, - when appropriate, the conversion rate specified in Article 158 (2) of the Act of Accession, - name(s) and address(es) of the owner(s) or charterer(s) and, if the owner is a corporate body or a partnership, its representative(s), - period for which permission to fish is requested, - intended method of fishing, - intended area of fishing. 4. The Commission shall examine the proposals for periodic lists referred to in paragraph 1 and shall approve periodic lists, which it shall forward to the Portuguese authorities and to the competent control authorities at least four working days before the date set for their entry into force. 5. The Portuguese authorities may request the Commission to replace a vessel named on a periodic list but unable for reasons of force majeure to fish during the period specified, or any part thereof, Any replacement vessel must be included in the lists referred to in Article 2. The Commission shall, without delay, notify any alteration of the periodic lists to the Portuguese authorities and to the competent control authorities referred to in para- graph 4.
