On Zhuanghe tables, clams are a daily freshness: stir-fried spicy with garlic and beer, or in a bowl of clam noodles whose broth needs no MSG. The gentle flats of the Yellow Sea’s north shore have earned the name ‘the world’s clam vault’ — Manila clams and other bivalves thrive here. Farmers sow seed clams on the flats and let the natural tides feed them for two to three years; the long growth gives firm flesh and full sweetness. According to local plans, Zhuanghe’s marine aquaculture covers over 60,000 hectares with total output in the hundreds of thousands of tonnes, making it a national base for shellfish farming and export. From flats to table — and to frozen boxes bound for markets at home and abroad — these small sweet clams are the sea flavour Zhuanghe offers the world.
