Book excerpt: This step-wise guide aims to assist with the implementation of relevant international instruments pertaining to deep-sea fisheries and biodiversity conservation in areas beyond national jurisdiction, especially the high seas, into national policy and law. This guide focuses on the incorporation and transposition of international rules, standards, and recommended practices and procedures into national policy and law. It addresses the key measures for making international obligations effective at the national level and suggests possible options for integrating those measures into the national legal framework. Legislative examples are also provided to illustrate how certain provisions have been incorporated into primary or secondary legislation. The guide first addresses the establishment of a national policy, followed by a description and analysis of essential legislative provisions regarding deep-sea fisheries and the conservation of marine biological diversity in areas beyond national jurisdiction. This guide is thus relevant to policy-makers, parliamentary draftpersons, and parliamentarians.
