A/RES/60/31 “flags of convenience” as well as to require that a “genuine link” be established between States and fishing vessels flying their flags, and calls upon States to implement the Declaration as a matter of priority; 40. Requests States and relevant international bodies to develop, in accordance with international law, more effective measures to trace fish and fishery products to enable importing States to identify fish or fishery products caught in a manner that undermines international conservation and management measures agreed in accordance with international law, and at the same time to recognize the importance of market access, in accordance with provisions 11.2.4, 11.2.5 and 11.2.6 of the Code, for fish and fishery products caught in a manner that is in conformity with such international measures; 41. Encourages further work by competent international organizations, including the Food and Agriculture Organization of the United Nations and subregional and regional fisheries management organizations and arrangements, to develop guidelines on flag State control of fishing vessels; 42. Recognizes the need for enhanced port State controls to combat illegal, unreported and unregulated fishing, urges States to cooperate, in particular at the regional level and through regional and subregional fisheries management organizations and arrangements, and encourages States to apply the model scheme on port State measures endorsed by the Committee on Fisheries at its twenty-sixth session in March 20056 at the national and regional levels, to promote its application through regional fisheries management organizations and arrangements and bodies, and to consider, when appropriate, the possibility of developing a legally binding instrument; 43. Calls upon all States to ensure that vessels flying their flag do not engage in trans-shipments of fish caught by fishing vessels engaged in illegal, unreported and unregulated fishing, and, individually or through regional fisheries management organizations or arrangements, to develop more effective enforcement and compliance measures to prevent and suppress such trans-shipments in accordance with international law; 44. Urges States, individually and through relevant regional fisheries management organizations and arrangements, to establish mandatory vessel monitoring, control and surveillance systems for fishing vessels, including the sharing of information on fisheries enforcement matters, to join the existing voluntary International Monitoring, Control and Surveillance Network for FisheriesRelated Activities and to consider the possibility, when appropriate, of transforming the Network, in accordance with international law, into an international unit with dedicated resources that can assist fisheries enforcement agencies; 45. Encourages and supports the development of a comprehensive global record within the Food and Agriculture Organization of the United Nations of fishing vessels, including refrigerated transport vessels and supply vessels, that incorporates available information on beneficial ownership, subject to confidentiality requirements in accordance with national law, and urges flag States to require that all their large-scale fishing vessels operating on the high seas be fitted with vessel monitoring systems no later than December 2008, or earlier if so decided by the flag State or any relevant regional fisheries management organizations or arrangements, as called for in the 2005 Rome Declaration on Illegal, Unreported and Unregulated Fishing; 10
