Koh Samui is a fishing island with centuries of maritime tradition. Seafood is caught every night, and by morning it appears in restaurants and markets. The freshness of seafood on Samui is not a marketing slogan — it's simply a geographic fact.

What Comes from Samui's Waters

In the warm Gulf of Thailand waters surrounding the island, fishermen catch:

  • Tiger and king prawns — the most popular seafood among tourists. Large in size, slightly sweet flesh. Best preparation: grilled with garlic and butter.
  • Blue crab (poo) — Thai crab with delicate white meat. Prepared as crab curry with curry powder (pu pad pong karee), stir-fried with ginger, or simply boiled. Price: ฿350–500 per piece.
  • Lobster — a seasonal product, mainly caught off southern Samui's shores. Tourist restaurant prices are higher; the best value is at village fish restaurants in Mae Nam and Taling Ngam.
  • Squid and octopus — affordable and delicious. Squid is deep-fried (pla muk tod), grilled with salt, or cooked in chili sauce. Price: ฿120–200 per dish.
  • Mussels in the shell — steamed with lemongrass, ginger, and galangal, or pan-fried. Portion: ฿150–250.
  • Fish: snapper, grouper, barracuda, tuna — choose fresh fish from the display, then specify the preparation: charcoal-grilled whole (pla pow), in three-flavour sauce (pla rad prik), or Cantonese-style steamed with ginger.

How to Choose a Good Seafood Restaurant

The golden rule: fresh fish on ice in front of the restaurant. If you see a display of live or chilled seafood, that's a good sign. Quality indicators:

  • Fish eyes — clear, not cloudy
  • Gills — bright red
  • Smell — oceanic, not foul
  • Mussels in shells — closed (if open and doesn't close when touched — avoid)
  • Restaurant full of locals — a reliable indicator
