When adopting delegated acts as referred to in paragraph 1, the Commission shall act in accordance with this Regulation.

In order for its species to be added to Annex IV, an aquatic organism must have been used in aquaculture in certain parts of the Union for a long time (with reference to its life cycle) with no adverse effect, and its introduction and translocation must be possible without the coincident movement of potentially harmful non-target species.

Member States may request the Commission to add species to Annex IV. Member States may provide scientific data to prove coherence with relevant criteria for adding species to Annex IV. The Commission shall decide on the suitability of a request within 5 months of its receipt, excluding the time for the Member State to provide additional information if the Commission so requests.

Member States concerned may, in respect of their outermost regions as referred to in Article 349 of the Treaty on the Functioning of the European Union, propose the addition of species to be included in a separate part of Annex IV.

The Commission may adopt detailed rules for the implementation of paragraphs 4 and 5, and in particular the formats, the contents and the particulars of Member States’ requests for the addition of species and the information to be provided in support of such requests, in accordance with the procedure referred to in Article 30(2) of Regulation (EC) No 2371/2002.

The power to adopt the delegated acts referred to in Article 24 shall be conferred on the Commission for a period of 5 years from 24 April 2011 . The Commission shall make a report in respect of the delegated power at the latest 6 months before the end of the 5-year period. The delegation of power shall be automatically extended for periods of an identical duration, unless the European Parliament or the Council revokes it in accordance with Article 24b.

As soon as it adopts a delegated act, the Commission shall notify it simultaneously to the European Parliament and to the Council.

The power to adopt delegated acts is conferred on the Commission subject to the conditions laid down in Articles 24b and 24c.

The delegation of power referred to in Article 24 may be revoked at any time by the European Parliament or by the Council.

The institution which has commenced an internal procedure for deciding whether to revoke the delegation of power shall endeavour to inform the other institution and the Commission within a reasonable time before the final decision is taken, indicating the delegated power which could be subject to revocation and possible reasons for a revocation.

The decision of revocation shall put an end to the delegation of the power specified in that decision. It shall take effect immediately or at a later date specified therein. It shall not affect the validity of the delegated acts already in force. It shall be published in the Official Journal of the European Union .

The European Parliament or the Council may object to a delegated act within a period of 2 months from the date of notification.

At the initiative of the European Parliament or the Council, that period shall be extended by 2 months.

If, on expiry of the period referred to in paragraph 1, neither the European Parliament nor the Council has objected to the delegated act, it shall be published in the Official Journal of the European Union and shall enter into force on the date stated therein.

The delegated act may be published in the Official Journal of the European Union and enter into force before the expiry of that period if the European Parliament and the Council have both informed the Commission of their intention not to raise objections.

If either the European Parliament or the Council objects to the delegated act within the period referred to in paragraph 1, it shall not enter into force. The institution which objects shall state the reasons for objecting to the delegated act.

This Regulation shall enter into force 20 days following its publication in the Official Journal of the European Union.

It shall apply six months after a Commission's Regulation on implementing rules referred to in Article 24(3) enters into force, but not later than 1 January 2009.

However, the provisions contained in Chapter I and Chapter II as well as Article 24, shall be applicable as from the date of entry into force of the Regulation.
