Sustainable fisheries, including through the 1995 Agreement for the Implementation of the Provisions of the United Nations Convention on the Law of the Sea of 10 December 1982 relating to the Conservation and Management of Straddling Fish Stocks and Highly Migratory Fish Stocks, and related instruments A/RES/68/71 beneficial owners and others who support or engage in illegal, unreported and unregulated fishing by identifying vessels engaged in such fishing and by depriving offenders of the benefits accruing from it, as well as by cooperating with developing countries to systematically identify needs and build capacity, including support for monitoring, control, surveillance, compliance and enforcement systems; 51. Urges States to exercise effective control over their nationals, including beneficial owners, and vessels flying their flag, in order to prevent and deter them from engaging in illegal, unreported and unregulated fishing activities or supporting vessels engaging in illegal, unreported and unregulated fishing activities, including those vessels listed by regional fisheries management organizations or arrangements as engaged in those activities, and to facilitate mutual assistance to ensure that such actions can be investigated and proper sanctions imposed; 52. Also urges States to take effective measures, at the national, subregional, regional and global levels, to deter the activities, including illegal, unreported and unregulated fishing, of any vessel which undermines conservation and management measures that have been adopted by subregional and regional fisheries management organizations and arrangements in accordance with international law; 53. Calls upon States not to permit vessels flying their flag to engage in fishing on the high seas or in areas under the national jurisdiction of other States, unless duly authorized by the authorities of the States concerned and in accordance with the conditions set out in the authorization, and to take specific measures, including deterring the reflagging of vessels by their nationals, in accordance with the relevant provisions of the Convention, the Agreement and the Compliance Agreement, to control fishing operations by vessels flying their flag; 54. Urges States, individually and collectively through regional fisheries management organizations and arrangements, to develop appropriate processes to assess the performance of States with respect to implementing the obligations regarding fishing vessels flying their flag set out in relevant international instruments; 55. Reaffirms the need to strengthen, where necessary, the international legal framework for intergovernmental cooperation, in particular at the subregional and regional levels, in the management of fish stocks and in combating illegal, unreported and unregulated fishing, in a manner consistent with international law, and for States and entities referred to in the Convention and in article 1, paragraph 2 (b), of the Agreement to collaborate in efforts to address these types of fishing activities; 56. Urges regional fisheries management organizations and arrangements to further coordinate measures for combating illegal, unreported and unregulated fishing activities, such as through the development of a common list of vessels identified as engaged in illegal, unreported and unregulated fishing or the mutual recognition of the illegal, unreported and unregulated vessel lists established by each organization or arrangement; 57. Reaffirms its call upon States to take all necessary measures consistent with international law, without prejudice to a State’s sovereignty over ports in its territory and to reasons of force majeure or distress, including the prohibition of vessels from accessing their ports followed by a report to the flag State concerned, when there is clear evidence that they are or have been engaged in or have supported illegal, unreported and unregulated fishing, or when they refuse to give information either on the origin of the catch or on the authorization under which the catch has been made; 13/31
