The catching, retention on board, transhipment or landing of marine mammals or marine reptiles referred to in Annexes II and IV to Directive 92/43/EEC and of species of seabirds covered by Directive 2009/147/EC shall be prohibited.

When caught, species referred to in paragraph 1 shall not be harmed and specimens shall be promptly released.

Notwithstanding paragraphs 1 and 2, the retention on board, transhipment or landing of specimens of marine species referred to in paragraph 1 which have been caught accidentally, shall be permitted as far as this activity is necessary to secure assistance for the recovery of the individual animals and to allow for scientific research on incidentally killed specimens, provided that the competent national authorities concerned have been fully informed in advance as soon as possible after the catch and in accordance with applicable Union law.

On the basis of the best available scientific advice a Member State may, for vessels flying its flag, put in place mitigation measures or restrictions on the use of certain gear. Such measures shall minimise, and where possible eliminate, the catches of the species referred to in paragraph 1 of this Article and shall be compatible with the objectives set out in Article 2 of Regulation (EU) No 1380/2013 and be at least as stringent as technical measures applicable under Union law.

Measures adopted pursuant to paragraph 4 of this Article shall aim at achieving the target set out in point (b) of Article 4(1). The Member States shall, for control purposes, inform the other Member States concerned of provisions adopted under paragraph 4 of this Article. They shall also make publicly available appropriate information concerning such measures.
