There are no oyster farms in the Knysna lagoon. A small government-funded facility in the Keiskamma estuary is the only oyster farm in an estuary in South Africa. The majority of oyster production is undertaken in marine bays such as Nelson Mandela Bay near Port Elizabeth and Saldanha Bay on the West Coast. Oysters filter-feed on plankton in the water, are regularly inspected and graded for size and after harvest, conditioned in tanks of fresh seawater before graded again, packed and shipped via a cold chain. Seed oysters are grown out in offshore systems based in sheltered bays.
