In celebration of World Ocean Day, Sandu'ao — a historic floating fishing village in Ningde, Fujian Province — comes into focus. Known as the hometown of China's large yellow croaker, Sandu'ao has a long tradition of marine aquaculture. Today, the village is embracing more sustainable practices by gradually replacing traditional floats and materials with eco-friendly alternatives. This transformation reflects a broader effort to protect marine ecosystems while preserving the livelihoods of coastal communities.
