Oyster Farming

​​​​​​Tasmanian oysters are recognised as some of the highest quality in Australia. With several operators across the state, oyster farming is one of Tasmania’s leading aquaculture sectors. 

​Oyster Farming in Tasmania​

Quality oysters require clean water and cool temperatures, making Tasmania an ideal location for oyster farming. With a very low impact on the environment and generating low emissions and waste, oysters are one of the most sustainable species to farm.

Tasmanian shellfish production is largely based around oysters, with several active farming operations across the state at varying scales. ​

Most Tasmanian oysters are sold to domestic markets, with a small amount exported overseas. The industry supports over 300 jobs directly and produces over 3 million dozen oysters per year – which had a farm gate value of over $40 million for the 2021–22 financial year. 

Key species

Oyster species currently being farmed in Tasmania include:

  • Cassostrea gigas (Pacific oysters)
  • Ostrea angasi (Australian flat oysters)

Cultivation Methods

​In Tasmanian aquaculture, oysters seed is spawned in a hatchery facility before being transported to a marine farm to mature. The hatcheries also grow different types of microalgae as feed for the developing oysters.

On a marine farm, oysters are generally placed in mesh baskets or trays, which are attached to rack and rail or BST systems (an adjustable long line system offering the ability to raise and lower the height of stock) for on-growing. Farmed oysters require frequent handling to ensure good quality product. 

When at optimal condition, oysters are harvested. Being filter-feeders that receive their nutrition from the natural environment, oysters have minimal impact to marine surroundings and wildlife.

Oyster FAQs

What is POMS? 

POMS stands for Pacific Oyster Mortality Syndrome and is a significant biosecurity threat for Australian oysters. It was first detected in Tasmania in early 2016, and since then, Biosecurity Tasmania has been working with the Tasmanian oyster industry to design adaptation techniques and manage the impact of the disease. 

POMS has affected oyster productivity in Tasmania, but is now being controlled by movement permits determining how and where oysters can be transported between farms in Tasmania. ​

For more information on POMS, visit Biosecurity Tasmania or learn more about ShellMAP, a program regulating the safe harvesting of oysters and other shellfish.
