 Our living marine resources are among the most precious on the planet. They provide food and livelihoods and support ecosystems essential for our survival. Their state and health is critical and requires urgent attention. Monitoring their status is crucial to manage them effectively and sustainably. For over 50 years, the Food and Agriculture Organization of the United Nations has assessed the state of world marine resources to support policy formulation and decision making. But as dominant fish stocks change and the tools to assess them evolve, FAO is updating its methodology to achieve a picture of the state of world stocks that has never been seen before. Combining the latest scientific evidence and information, this upgraded methodology will provide more accurate indices for the status of marine stocks and allow researchers to give a clear understanding of the state of global aquatic stocks, facilitate capacity development, target management approaches to improve the sustainability of our precious resources. This methodology is not just a tool for measuring stocks. It's a catalyst for change. By enhancing the transparency and ultimately the sustainability of fisheries, it will empower communities and safeguard our planet's natural resources for future generations. Let's work together to achieve this blue transformation for the people, for the planet.
