How Its Done

At Cowell Seafood Producers, the journey begins with the finest 6 to 8mm spat from trusted local hatcheries. The initial process involves carefully grading and thinning the oysters 4 to 6 times, ensuring each one has the space to grow. The magic happens as the oysters rotate through three distinct lease areas, allowing a consistent, premium product throughout the year. With an average grow-out time of 20 months from seed to sale, the oysters are nurtured with patience and precision using an adjustable longline (BST) system. This innovative method allows the efficient management of stock, ensuring the health and vitality of every oyster. The result is a superior product that embodies the pristine waters and natural beauty of Cowell, South Australia. Franklin Harbour Pacific Oysters stands out as the premier choice for discerning seafood lovers, offering an exquisite and unforgettable taste experience.
