The objective of the symposium will be to identify pathways to strengthen the science and policy interplay in fisheries production, management and trade, based on solid sustainability principles, for improved outcomes in practice. Ultimately, the debates and conclusions of the symposium will prepare the way for the development of a new vision for capture fisheries, outlining how the sector can respond to the complex and rapidly changing challenges facing society and support the planning process of the UN Decade of Ocean Science for Sustainable Development (2021-2030).
