Xiamen is an island city right on the sea, so the catch is genuinely fresh — and the way locals love to eat it is to walk the Bashi market (八市), pick their own razor clams, blood cockles, mantis shrimp, crab and fish, then carry it to a stall next door to cook Minnan-style: steamed, blanched, garlicky, letting the freshness lead rather than the seasoning.
Honestly, coming to Xiamen and not eating the seafood means missing one of the best things the city has. Xiamen is an island in southern Fujian with clean waters and a fresh catch landing every day. The seafood here belongs to the Minnan (闽南) school, which is clearly different from Sichuan or Hunan cooking — built on freshness and light seasoning, not numbing málà and not heavy flavours. The two most popular methods are steaming and blanching, to draw out the natural sweetness of the catch. The idea is simple: the fresher it is, the less you do to it, letting the ingredient speak for itself. Mantis shrimp steamed plain with a ginger-vinegar dip, razor clams stir-fried with fragrant garlic, a whole fresh fish steamed with soy — simple, but good enough to order again.
The real heart of eating seafood like a Xiamen local isn't a smart restaurant — it's the Bashi market (第八市场, or 八市), the biggest and most famous fresh-seafood market in the old town. The way it works is "pick-and-cook" (代加工): you walk the stalls and choose your own seafood, pay by weight, then carry it to a nearby restaurant that cooks it for you on the spot. You get the freshest possible catch at a price you control. We picked the six things that tell the story of the Xiamen seafood table best — from the clams and mantis shrimp everyone orders, to 土笋冻 sandworm jelly, the local oddity for the brave — along with how to do pick-and-cook without getting overcharged.
From the favourites every table orders, to the local oddity that tests your nerve.

Mantis shrimp (虾蛄, also called 皮皮虾) are a Xiamen favourite — plump and sweet. The best way to eat them is steamed plain, to get the full natural sweetness, with a ginger-vinegar dip on the side; some places do them stir-fried with garlic or salt-and-pepper too. They're a little fiddlier to peel than prawns but well worth it, and in season they're packed with roe. It's one of the dishes that says "sea town" loudest about Xiamen. Prices swing with the season, so ask the price per catty before you order.
Razor clams (圣子/蛏) are long, blade-shaped shells with sweet, tender meat, and Bashi has fresh piles of them daily. Xiamen locals like them stir-fried with plenty of ginger, scallion and garlic, or steamed over glass noodles with crispy garlic, to keep the clam's sweetness front and centre. When choosing, look for ones whose foot reacts when touched — that means they're alive. Razor clams cook fast, so overcooking turns them rubbery; a good kitchen flash-fries them over high heat so the meat stays juicy. A dab of seafood dip and they're a full mouthful — an easy starter for anyone new to less familiar seafood.
Blood cockles (血蚶/泥蚶) are small cockles that, when you open them, hold a red liquid that looks like blood — hence the name — long eaten along China's southern coast. The classic way is to blanch them in hot water just until the shells barely open, so the meat stays tender and juicy, then dip them in soy-garlic-chilli sauce; the taste is sweet, rich and lightly salty, and fans call it the truest taste of the sea. Honestly, if they're served very rare some people won't be used to it — so choose a busy stall with fast turnover, have them blanched through properly, and eat them hot for the safest and best result.
Fujian crab — both the big-clawed mud crab (青蟹) and the swimming crab (梭子蟹) — has firm, rich meat. The most classic Minnan move is to steam it whole, to keep all the sweetness and the roe intact, with a ginger-vinegar dip. Some places do sticky rice steamed with crab, where the rice soaks up the crab fat, or a satay (沙茶) stir-fry. Crab is best when it's full of roe (often in autumn into winter). When choosing, look for one that's still moving strongly and feels heavy for its size — that means the meat is dense. It's a centrepiece dish you order to share, and the whole table smiles.
Bashi has several kinds of fresh fish each day, depending on what the boats brought in. The Minnan method that honours freshness most is to steam a whole fish with soy, scattered with shredded ginger and scallion, then finished with hot oil and steamed-fish soy — giving you sweet, tender flesh and a clean sea aroma that isn't buried under heavy seasoning. If the fish is truly fresh there's barely any fishy smell at all. This is a great dish for anyone who doesn't eat spicy, and the clearest example of how the Minnan kitchen favours freshness over heavy seasoning. A whole fish is priced by weight, so ask the price per catty before you order.

And now the most famous oddity of Minnan cooking — 土笋冻 (tǔsǔndòng) is a cool, translucent jelly set from the collagen of a coastal "sea worm" (a sipunculid that lives in the mudflats). The worms are boiled until they release their collagen, and as it cools it sets into jelly with the worms suspended inside. It's eaten chilled with dips of soy, vinegar, garlic or mustard; the taste is mildly salty and umami, the jelly springy. Honestly, the look and the backstory put a lot of people off — but it's something Xiamen locals are genuinely proud of and rate among the city's top snacks. If you're game, one bite is a taste of the real local thing.
Pick-and-cook (代加工) is better value than a smart restaurant — but you need to know the steps and agree the price clearly every time.
Start at the Bashi market and look at several stalls before deciding. Freshness shows: mantis shrimp and crab still moving, clams whose meat reacts when touched, fish with clear eyes. Ask the price per catty (斤 = 500g) clearly before you point at anything, and compare two or three stalls. Popular items like mantis shrimp and crab swing with the season, so don't rush.
This is the most important step — watch the weighing with your own eyes, and have them say the total as a number before you pay. Some stalls have off scales or quietly add things you didn't ask for. If a number looks odd, ask again — that's fine. Photograph or note the price boards if you like. Pay cash or scan only the amount you agreed, and leave nothing vague.
Take your seafood to a restaurant near the market that cooks it (look for a 代加工 sign). Ask the cooking fee per dish and the method before you put it down — steamed, garlic stir-fry, satay, and so on. The fee is usually around ¥10–20 a dish. Be clear about how you want each item; for very fresh seafood, steam or blanch first, then add a bolder stir-fry. You can order drinks and rice on the side.
If you'd rather not pick your own, Xiamen has seafood restaurants (海鲜大排档) with live tanks out front — point at what you want and they cook it all in one place. It's easier, but usually pricier than buying at the market yourself. The same rules still apply — ask the price per catty and watch the weighing before agreeing. Good places have clear price boards; avoid any spot with no prices shown or that pushes pricier items than you need.
Seafood is only one part — Xiamen also has satay noodles, oyster omelette and street eats waiting.
