Aquatic food systems are integral to building healthy and resilient communities worldwide. They offer an irreplaceable – and at times the most affordable – source of micronutrients, essential fatty acids and high-quality protein for vulnerable populations in many of the world’s lowest-income countries. More than one billion people rely on fish and other aquatic foods as their primary source of animal protein. Aquatic food systems are also key to sustainable livelihoods. Fisheries and aquaculture provide jobs, employment and income for millions, including women and young people. Around 60 million people worldwide work in aquaculture and fisheries and fish are among the world’s most valuable items of global trade, worth 164 billion USD in 2018.
