What Are Gold Doubloon Oysters?
Gold Doubloon Oysters are farmed Eastern oysters from the Indian River Lagoon near Sebastian, Florida. Treasure Coast Shellfish cultivates them south of the Sebastian Inlet. The line uses off-bottom floating cages in this growing area. The farm is the only active oyster lease in the immediate zone.
On the half shell the profile reads briny with a clean mineral finish. Salinity near 28 ppt shapes that bold front-of-palate snap. A subtle sweetness and hazelnut note follow mid-palate. Firm meats hold liquor well for raw service.
The shell is thick, flattened, and highly variable in shape. Cups can run round and irregular or oval with concentric growth rings. Color typically runs light to medium brown with gold or yellow highlights. That golden shell earns the doubloon trade name on half-shell tags.
How Did Gold Doubloon Oysters Get Their Name?
Gold Doubloon Oysters take their name from Treasure Coast history. The label references the 1715 Spanish treasure fleet that wrecked off this coast. Locals long called lost gold coins doubloons after those wrecks. Treasure Coast Shellfish borrowed that story for its premium large-cup line.
The farm uses Gold Doubloons for its three-inch-and-larger harvest grade. Smaller shell from the same lease sells as Sebastian Silvers. Chefs read the doubloon tag to spot the bigger, brinier cup on distributor lists. The branding ties lagoon flavor to Sebastian maritime lore.
Buyers see Gold Doubloons on tags and distributor manifests from Indian River County. The trade name separates this grade from other Florida Virginica programs. It signals Sebastian provenance and Treasure Coast Shellfish as the source grower. That clarity helps raw bars order the correct Florida cup.
About Treasure Coast Shellfish
Treasure Coast Shellfish is the only commercial oyster farm on Florida’s Treasure Coast. CEO Nicolette Mariano runs the business from the historic Sembler dock in Sebastian. Her crew works a leased plot south of the Sebastian Inlet in the Indian River Lagoon. They harvest Gold Doubloons, Sebastian Silvers, and Treasure Coast grades year-round.
Mariano founded the farm after years in marine science and aquaculture logistics. The operation uses floating gear on the water plus shoreside sorting and packing. Crews cull barnacles and check each oyster before wholesale and retail orders ship. The farm filters millions of gallons of lagoon water daily while oysters grow.
The company sells direct through its website and regional seafood partners. Gold Doubloons represent the farm’s large-format Virginica for raw bars and retail. Floating cage culture keeps shells clean and cups deep in the lagoon’s moderate salinity. That method supports consistent briny flavor through the seasons.
Gold Doubloon Oysters Information

Location
Gold Doubloon oysters grow in the Indian River Lagoon near Sebastian, Florida. Treasure Coast Shellfish holds the only active oyster lease in this immediate growing area. The farm sits just south of the Sebastian Inlet on the Intracoastal waterway. Daily tides and lagoon salinity shape the line’s briny character.
The Indian River Lagoon stretches roughly 156 miles along Florida’s east coast. Salinity in the farm zone often runs between 21 and 35 ppt by season. That estuary mix feeds plankton-rich water to floating cages. Oysters fatten there into three-inch Gold Doubloon grades.
Harvest crews boat out from the Sembler working waterfront on the lagoon shore. They pull bags from off-bottom floats and grade shell on the dock. Live oysters ship to Florida restaurants, seafood markets, and wholesale accounts. Pelican Island National Wildlife Refuge sits just north of the lease.
