Illegal, Unreported and Unregulated (IUU) fishing represents a threat to global fisheries sustainability and maritime security, incorporating large-scale and highly mobile environmental, economic, and social concerns. In terms of fisheries governance, the threat from illegal fishing is often not a lack of rules and standards on the international, regional, and domestic level but rather vessels avoiding compliance with relevant conservation and management measures through their choice of jurisdictions. This in turn results from implementation failures and a general lack of enforcement by flag, coastal, port and market states, and states of nationality. This presentation will focus on the role of the state of nationality, whose jurisdiction was long held by global instruments as a complimentary means of eliminating IUU fishing but has been highlighted only to a limited extent in state practice. In this respect, the presentation will focus on the practice of the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) and its member states as a leader in combating IUU fishing. The authors suggest the last decade has been demonstrative of at least three key developments in the contemporary use of the active nationality principle of jurisdiction to address IUU fishing.
