and barramundi farmed in South Australia

SOUTH AUSTRALIA PRODUCES THE MOST DIVERSE AQUACULTURE IN AUSTRALIA, including subtidal and intertidal mollusc farming, sea-cage farming of finfish and a range of land-based systems.

There are six sectors of marine-based aquaculture in South Australia:

  • Southern bluefin tuna (wild-capture for ranching)
  • finfish (e.g. yellowtail kingfish and mulloway)
  • intertidal shellfish (e.g. oysters)
  • Subtidal filter-feeding shellfish (e.g. mussels and scallops)
  • Subtidal non filter-feeding shellfish (e.g. abalone)
  • Algae (e.g. macro-algae)

There are also three categories of land-based farming: A (e.g. yabbies), B (e.g. barramundi) and C (e.g. coastal abalone farms and hatcheries)

The state government, through the fisheries and aquaculture division of the Department of Primary Industries and Regions SA (PIRSA) has developed aquaculture resource management to ensure it develops in an ecologically sustainable way.

One of South Australia’s successful aquaculture ventures has been Clean Sea Tuna’s kingfish pens in Spencer Gulf pens. It has achieved excellent fish health and survival rates, running close to world’s best practice and outstanding sales growth.

The 100 oyster growers in South Australia’s seven main growing bays produced 55% of the nation’s Pacific oysters. This has increased since the POMS (Pacific Oyster Mortality Syndrome) virus hit Tasmanian oyster hatcheries in 2015. In 2016, the state government banned import of all live Pacific oysters, including oyster breeding stock (sat) from Tasmania.
