A/RES/71/123 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 200. Calls upon States, including through regional fisheries management organizations and arrangements, to play an active role in global efforts to conserve and sustainably use living marine resources, so as to contribute to marine biological diversity; 201. Encourages States, either individually or through regional fisheries management organizations and arrangements, as appropriate, to identify any spawning and nursery areas for fish stocks under their jurisdiction or competence and, where required, to adopt science-based measures to conserve such stocks during these critical life stages; 202. Expresses concern about the recent massive influx of sargassum seaweed into the waters of the Caribbean and its impact on aquatic resources, fisheries, shorelines, waterways and tourism, and encourages State s and relevant regional organizations to cooperate to better understand the causes and impacts of the influx, with a view to protecting the livelihoods of fishers and fishing communities and finding ways of beneficially utilizing the seaweed and environmen tally friendly ways of disposing of sargassum washed up on shore; 203. Recognizes the wide range of impacts of ocean acidification on marine ecosystems, and calls upon States to tackle the causes of ocean acidification and to further study its impacts; 204. Emphasizes the importance of developing adaptive marine resource management strategies and enhancing capacity-building to implement such strategies in order to enhance the resilience of marine ecosystems to minimize the wide range of impacts on marine organisms and threats to food security caused by ocean acidification, in particular the impacts on the ability of calciferous plankton, coral reefs, shellfish and crustaceans to build shells and skeletal structures and the threats this could pose to protein supply; XI Capacity-building 205. Reiterates the crucial importance of cooperation by States directly or, as appropriate, through the relevant subregional and regional organizations, and by other international organizations, including the Food and Agri culture Organization of the United Nations through its FishCode programme, including through financial and/or technical assistance, in accordance with the Agreement, the Compliance Agreement, the Code and its associated international plans of action, to in crease the capacity of developing States to achieve the goals and implement the actions called for in the present resolution; 206. Welcomes the ongoing work of the Food and Agriculture Organization of the United Nations in developing guidance on, and assi sting in the implementation of, the strategies and measures required for the creation of an enabling environment for sustainable small-scale fisheries, and encourages studies for creating possible alternative livelihoods for coastal communities; 207. Recalls that, in “The future we want”, States recognized the importance of building the capacity of developing countries to be able to benefit from the conservation and sustainable use of the oceans and seas and their resources, and in this regard emphasized the need for cooperation in marine scientific research to implement the provisions of the Convention and the outcomes of the major summits on sustainable development, as well as for the transfer of technology, taking into 36/40
