Millions of servings of sustainably sourced fish are being lost each year, with data from a study of thousands of tropical reefs showing that reef fish stocks could provide much more if sustainably maintained.
Coral reef fish are a critical source of nutritious food for many tropical communities, and managing such resources sustainably offers potential food security benefits, especially for nations facing high burdens of malnutrition.
“Well-managed reef fisheries can deliver sustainable supplies of nutritious aquatic foods while helping reef ecosystems and dependent communities increase their resilience to other stresses,” says Jessica Zamborain-Mason, interdisciplinary marine scientist at KAUST, who led the international research team. “Millions of people are losing out on sustainably sourced and nutritious food supplies.”
