Understanding the Dynamics of World Aquaculture and Seafood Trade
Aquaculture plays a vital role in providing essential nutrition to over one billion people globally, with more than 50% of food fish supply originating from this system. Seafood holds significant importance in international trade, surpassing all other animal proteins combined. However, challenges such as overexploitation of marine resources pose threats to future fisheries sustainability. Despite these challenges, aquaculture continues to be the fastest-growing food production system, contributing significantly to food fish supply.

Introduction to World Aquaculture
Global Stats on Aquaculture/Seafood Seafood provides essential nutrition for over one billion people More than 37% (by volume or weight) of world fish production is traded internationally Seafood is the most globally traded protein commodity by volume and value The value of international fish trade exceeds the international trade in all other animal proteins combined Over 75%of fisheries are considered fully or over exploited More than 50% of all food fish supply comes from aquaculture Aquaculture is world s fastest growing food production system 8% annual growth

Future of Marine Fisheries In trouble! Marine fisheries Over exploited or depleted resources: 25% of world marine resources 30% of highly-migratory tuna and tuna-like species 50% of highly-migratory oceanic sharks 65% of straddling and high seas resources

Where are the fish going to be produced? 90% of our fish is imported Low-income countries will dominate supply What are the environmental concerns? Why can t the USA compete?
