Eastern Oyster Sampling Quadrat

The Atlantic eastern oyster can grow to lengths of 6-10" long and can be found from the Gulf of St. Lawrence to Florida. These animals prefer brackish water but can be found on any Floridian coast attached to rocks, other oysters, or artificial substrate. Eastern oysters represent one of the most important commercial fisheries in Florida and are ecologically important due to their high filtration rates and ability to form reefs in areas of unconsolidated substrate.

Molluscan Fisheries staff at FWRI use PVC quadrats to determine the density of adult oysters on reefs.
