Blue foods play an indispensable role in global nutrition and livelihoods. For over 3 billion individuals, these aquatic resources are the backbone of essential nutrients and proteins. Additionally, approximately 800 million people rely on blue food systems for their income. Despite this, discussions about the future of food systems often overlook the significance of marine and freshwater resources.

Small-scale fisheries hold the key to sustainable blue food systems. An overwhelming majority—about 90%—of those employed in fisheries work in small-scale operations, which contribute around 40% of the global catch. These smaller operations face numerous environmental challenges, including climate change, pollution, and habitat destruction. However, they also possess remarkable resilience and potential. Empowering these fishers is crucial for ensuring responsible and sustainable practices that can feed the world while protecting the environment.

Inspiring leaders across the globe are championing sustainability and inclusivity within blue food systems. Organizations like the North American Marine Alliance and projects such as Lift All Boats are fostering economic empowerment and fair compensation for fishers. Initiatives led by figures like Imani Black, founder of Minorities in Aquaculture, are promoting diversity and hands-on training in aquaculture. Innovators like Chef Eric Gephart highlight the integration of traditional methods with modern sustainable technologies. Efforts from entities such as Wholechain and Fed By Blue aim to enhance traceability and transparency in supply chains, supporting responsibly sourced blue foods. Oko Farms in New York City exemplifies urban aquaponics, demonstrating how limited spaces can be utilized efficiently for local protein production.

The actions taken today will determine the future of global blue food systems. Encouragingly, preliminary data suggests progress in the right direction. In the United States, fishery health appears to be improving, and the United Nations has released guidelines for sustainable aquaculture. Every individual can contribute by choosing diets and supporting businesses that prioritize sustainability and small-scale fisheries. Together, we can build a future where blue foods thrive sustainably, benefiting both people and the planet.
