Introduction
品种介绍Razor clams (both constricted and bamboo types) come mainly from Fujian, Zhejiang and Jiangsu — traditional tidal-flat producers with long farming history and large supply.
Tender, sweet with a slight crunch; fattest Apr–Oct; a high-frequency coastal family shellfish.
Holding Environment
暂养环境Xian Mancang holding advisor: temperature, salinity, water quality and density references per species — feel free to exchange holding experience.
Requires shallow water with high oxygen: 10–22°C, salinity 20–30‰, density 30–50 kg per cubic meter (thin layer in shallow tanks).
Must desand before sale: soak in circulating seawater 8–12 hours; hold 2–3 days; water deterioration kills fast — change water frequently. Parameters above are reference values — adjust to water quality and season.
Economic Value
经济价值Mid-range pricing (15–30 CNY/jin) by size and condition; large 'razor clam kings' carry premiums. Spring-summer is the consumption peak with both foodservice and home demand; dried razor clams smooth off-season inventory.
