The provisions of the agreement are not limited to good practice: these are legal obligations. Governments that have approved it must comply with their obligations as members of regional fisheries management organizations (PROs), international bodies empowered to manage fisheries resources. UNFSA`s principles and commitments have contributed significantly to the development of the legal framework and specific management measures for PMOs and other international legal instruments (2), such as the UN agreement on port state measures adopted in 2009 by the Food and Agriculture Organization of the United Nations (PSMA). As the UN Secretary-General`s report shows, which was presented at this review conference7, the overall status of large migratory fish stocks and straddling fish stocks has not improved since the first review conference in 2006.8 Since 2010, the overall status of large migratory and straddling stocks has not improved since 2010. With information on shark species, 60% are potentially overexploited or depleted.11 The agreement attempts to achieve this goal by establishing a framework for cooperation in the conservation and management of these resources. It promotes good governance in the oceans through effective management and conservation of offshore resources, including setting detailed minimum international standards for the conservation and management of straddling fish stocks and large migratory fish stocks; Ensure that conservation and management measures for these stocks are compatible and consistent in areas under national jurisdiction and on the adjacent high seas; Ensure that effective mechanisms are in place to ensure compliance and implementation of these measures on the high seas; and recognising the specific conservation and management requirements of developing countries, as well as development and participation in fisheries for the two types of stocks mentioned above. Under the agreement, “limits are set to limit harvesting within safe biological limits, within which stocks can achieve maximum sustainable yield.” 14 These points form the outer limit of sustainable fishing. Four of the five PROs have also not taken sufficient action to better protect the threatened shark species that are discovered in fishing fisheries under their management. To date, none have implemented scientifically sound management plans for all fishing-related shark species in their area. In 1995, the world`s heads of state and government adopted the UN Agreement on Fisheries Resources1 to “ensure the long-term conservation and sustainable exploitation of straddling fish stocks and large migratory fish stocks.” The agreement, in force since 2001, is the main international instrument to encourage countries to assume the cooperation necessary to manage common fish stocks.
