1.In the case of non-routine introductions, the release of aquatic organisms into open aquaculture facilities shall be subject, if necessary, to the conditions set out in paragraphs 2, 3 and 4.
2.The aquatic organisms shall be placed in a designated quarantine facility within the territory of the Community in accordance with the conditions set out in Annex III, for the purpose of constituting a brood-stock.
3.The quarantine facility may be located in a Member State other than the receiving Member State, provided that all Member States concerned agree and that this option has been included in the environmental risk assessment under Article 9.
4.If appropriate, only progeny of the introduced aquatic organisms may be used in aquaculture facilities of the receiving Member State, provided that no potentially harmful non-target species are found during quarantine. Adult stock may be released in those cases where the organisms do not reproduce in captivity or are fully reproductively sterile, providing the absence of potentially harmful non target species is confirmed.
