We are deeply troubled by the continuously degrading accumulated trends at the global level in the status of marine fish stocks due to unsustainable practices, challenges from illegal, unreported and unregulated fishing, overcapacity and overfishing, climate change, ocean acidification, loss of biodiversity, pollution and aquatic ecosystems degradation, while noting variability between and within regions. We therefore call for decisive and collective action to ensure sustainable fisheries and aquaculture systems, including by, inter alia, enhancing transparency, the use of technology, enhancing science- and knowledge-based management, promoting, scaling up and replicating successes, and working together to end illegal, unreported and unregulated fishing. As a key pillar of the ocean economy, fisheries and aquaculture provide livelihoods, economic opportunities, food security and nutrition to millions worldwide. We emphasize the urgent need to improve sustainability of fisheries and aquaculture to combat malnutrition and poverty, particularly for people in vulnerable situations, while ensuring the long-term health of marine ecosystems.
