Any entry into or departure from the Mauritanian fishing zone by an EU vessel holding a fishing authorisation must be notified to Mauritania at the latest 36 hours before entry or exit, with the exception of tuna seiners, pole-and-line tuna vessels and longliners, in respect of which this period is reduced to 6 hours.
Au cours de leur présence dans la zone de pêche mauritanienne, les navires de l'Union européenne doivent veiller en permanence les fréquences d'appel internationales (VHF Canal 16 ou HF 2182 KHz).
