Southern China’s Underwater ‘Donuts’ Are Feeding the Future
Imagine a farm, but instead of fields and tractors, it’s made of giant floating donuts 🌊🍩. In Zhanjiang, Guangdong Province, nearly 300 high-tech deep-sea cages are revolutionizing how China grows fish sustainably. Each ring-shaped structure sinks 7-8 meters underwater and can hold 50,000 kg of fish – that’s like packing 13 soccer fields’ worth of traditional ponds into one smart setup!
Why This Matters for the Planet
With global seafood demand rising faster than Marvel movie sequels 🎬🐟, these farms use space efficiently while reducing environmental strain. The project highlights China’s push for blue food systems that protect marine ecosystems. Bonus: It’s a win for food security in Asia’s fastest-growing economies!
Innovation Meets Tradition
While the tech feels straight out of a sci-fi novel, local fishers are already collaborating with researchers. As one worker told us: ‘This is how we keep our seas full and our plates fuller.’ 👨🌾🇨🇳
