Live oysters Sabah · Malaysia
Live oysters from four contract farm sites in Sabah, purged at our partner hatchery and flown to the Peninsula, on your table within 72 hours.
Why it matters
Most oysters on a Malaysian table arrive with no history. No one can tell you which bay they came from, how long they purged, or whether anyone tested the water that week.
We built Ocean Tide Ventures to close that gap. Between our partner in Sabah and us on the Peninsula, every stage is accounted for: the microalgae that feed the spat, the racks the farmers work, the tanks the oysters purge in, and the sealed, batch coded box that leaves our chill room. Every oyster we sell can be traced back to the raft it grew on.
The process
Six stages across two companies, and one unbroken record. The split is deliberate, and the chain is not broken by it.
01 Sea Life
Sea Life Aquaculture hatches the spat at Tawau, culturing the microalgae that feed the larvae. Controlling the seed is what makes everything downstream predictable, which is why our partner owns that step rather than buying seed in.
02 Sea Life
Spat no bigger than a fingernail are graded by hand and moved into nursery trays, checked, cleaned and thinned until they are strong enough for open water. They then go out to the contract farmers with the racks and baskets to grow them in.
03 Contract farmer
Rack and raft lines worked by contract farmers on four sites across Sabah. Baskets are turned, thinned and graded by hand until the shells are ready. The equipment and the standard arrive with the spat, so husbandry does not vary site to site.
04 Contract farmer
Pulled by hand on the tide, sorted on the boat and back on shore within the hour. Sea Life buys the harvest back at an agreed rate, so a farmer carries the work and not the market.
05 Sea Life
Oysters purge in filtered, ultraviolet sterilised seawater at the Tawau hatchery, following Malaysian research and FAO guidance. They leave the tanks clean, closed and graded, and they leave with a batch code.
06 Ocean Tide Ventures Handover at KLIA
Chilled, sealed and flown to KLIA on the daily morning run, where we take delivery. From the airport to the counter the chain is ours, and every box still carries the code it was given in Sabah.
Where the oysters come from
Everything we sell today comes out of Sabah, grown on four contract farm sites supplied and bought back by Sea Life Aquaculture, our exclusive partner, and purged at their hatchery at Tawau. Melaka and Setiu are in development, and we would rather name them honestly than imply we are already in the water.
The sites
Four contract sites Warm tropical water
Kunak · Bambangan · Sandakan · Tuaran
Every oyster we sell is grown on these four sites by contract farmers: Kunak and Bambangan on Darvel Bay, Sandakan to the north, Tuaran on the west coast. Sea Life supplies the spat and the equipment and buys the harvest back.
Crassostrea belcheri
Opening soon Historic shipping straits
Straits of Melaka
One of the busiest straits on earth, and a strong oyster water. Our shortest route to the Klang Valley, and the peninsula's longest half-shell tradition.
Crassostrea belcheri
Opening soon Mangrove wetlands
Terengganu
Brackish, tannin-rich water draining out of the Setiu wetlands on the east coast, on a monsoon season offset from Sabah. Not producing for sale yet.
Crassostrea iredalei
The oysters
Both of Malaysia's commercially important native oysters are grown for us. They are not interchangeable, and we would not want them to be.
Crassostrea iredalei
The small one. Deep-cupped, firm, and clean on the finish, a slow grower off our sheltered Sabah bays. The oyster to hand someone who says they don't like oysters.
Crassostrea belcheri
The big one. Grown fast and full in the warm, plankton-rich water off Sabah, with a creamy weight that stands up to heat, butter and fire.
Food safety
Oysters are filter feeders. They concentrate whatever is in the water, which is exactly why depuration is not optional and why we will not sell an untested batch.
Trace a batchIoT sensors track salinity, temperature, tide and rainfall across every site. When conditions move outside range, harvesting stops before there is a problem.
Filtered, UV-sterilised seawater, run to protocols drawn from Malaysian research and FAO guidance. Time in the tank is measured, not estimated.
Batches are tested before release. An untested batch does not leave the building.
Farm, line, harvest date and depuration record travel with every box, so any oyster can be walked back to the water it grew in.

Where to find us
Before the wholesale orders and the restaurant accounts, there is a folding table, a bucket of ice and someone shucking to order under a market light. That is still where most people taste a Malaysian oyster for the first time.
We keep doing it because it is the honest test. There is no menu description to hide behind when the person is standing in front of you watching you open it.
Shucked to order with lime, Thai sauce and cheese sauce. Follow us on TikTok. That is where we announce where the stall will be.
Styrofoam box with ice, shucked or whole, from 15 pieces. Order on WhatsApp and collect or have it delivered.
We bring the shucking station, the staff and the ice display to your venue. From 50 pieces.
On TikTok
Harvests, stall days and a great deal of shucking. Videos play from TikTok, nothing loads until you press play.

The wider point
Oysters are one of the few animal proteins that improve the water they are farmed in. They need no feed, no freshwater and no antibiotics, a single adult filters hundreds of litres a day, and the reef structure the racks create gives juvenile fish somewhere to hide.
Alongside oysters we supply spat, seaweed and microalgae to other Malaysian growers, and work with research institutions on triploid development. The goal was never to be the only oyster farm in Malaysia. It was to make it possible for there to be many.
By the numbers
A daily 8am run from Tawau to KLIA puts our oysters on a Klang Valley table in 72 hours or less.
IoT water sensors and predictive analytics let us stop harvesting before conditions turn, not after.
What a B40 household on the buy back programme can earn, RM 3,000 to RM 4,000 a month.
Every box leaves with its farm, line and harvest date attached.
From the water
Harvest reports, food-safety explainers and what we are learning as we go.
Come and see
Farm visits run daily from 11:00 to 17:00, rafts, hatchery, depuration tanks and chill room, finishing with oysters shucked in front of you.
