In the coastal city of Zhanjiang in south China’s Guangdong Province, a groundbreaking aquaculture project is making waves in sustainable fish farming. Known as the “donut” ocean farm, this innovative initiative features nearly 300 donut-shaped deep-sea cages that are transforming the landscape of seafood production.
Each of these circular cages extends seven to eight meters underwater, creating an expansive habitat for marine life. Remarkably, every cage can hold up to 50,000 kilograms of fish, matching the yield of 13 hectares of traditional land-based ponds. This significant increase in efficiency not only boosts production but also minimizes the environmental footprint associated with conventional aquaculture.
The “donut” design is more than an aesthetic choice; it represents a strategic approach to sustainable farming. By situating the cages in the open sea, the farm harnesses natural ocean currents to provide a cleaner and more oxygen-rich environment for the fish. This method reduces the reliance on artificial aeration and decreases the accumulation of waste products, promoting healthier fish and a more balanced ecosystem.
This pioneering project exemplifies China’s commitment to advancing sustainable aquaculture practices. As global demand for seafood continues to rise, such innovations are critical in meeting consumption needs without depleting natural fish populations or causing undue harm to marine environments.
Industry experts believe that the success of the Zhanjiang “donut” ocean farm could set a precedent for similar projects worldwide. By combining large-scale production with environmentally friendly practices, the model offers a viable solution to the challenges faced by the global aquaculture industry.
The “donut” ocean farm not only contributes to food security but also supports the local economy by creating jobs and fostering technological development in the region. Tourists and marine enthusiasts are showing interest in the site, adding a new dimension to the area’s cultural and economic appeal.
As nations seek sustainable ways to nourish growing populations, China’s innovative approach in Zhanjiang demonstrates the potential of combining traditional aquaculture with modern technology. The “donut” ocean farms symbolize a harmonious balance between human needs and environmental stewardship, pointing the way toward a more sustainable future for our oceans.
