Harvesting fish and shellfish from offshore farms could help provide essential protein to a global population set to expand a third to 10 billion by mid-century, researchers said Monday. Suitable open-sea zones have the potential to yield 15 billion tons of fish every year, more than 100 times current worldwide seafood consumption, they reported in the journal Nature Ecology & Evolution. Coastal and inland aquaculture already accounts for more than half of the fish consumed around the world. Many regions, especially in Africa and Asia, depend on fish for protein.
