Southern Bluefin Tuna

nullThunnus maccoyii

Biology

Found in the southern hemisphere, Southern Bluefin Tuna (Thunnus maccoyii) are a large and fast-swimming pelagic fish.

The farming of Southern Bluefin Tuna currently generates the highest farm-gates sales in South Australia’s aquaculture industry. Tuna farming is unique to South Australia and its development in 1991 initially put South Australian aquaculture on the map.

They spawn between September and April each year in the only known spawning grounds in the Indian Ocean, between the north-west Coast of Australia and Indonesia. The eggs are estimated to hatch within two to three days. Southern Bluefin Tuna reach approximately 15 kilograms in the first two years and this size tuna is the principal wild catch of the Australian Southern Bluefin Tuna industry.

Distribution

Southern Bluefin Tuna exist largely in the world’s southern oceans and congregate in the coastal waters off southern Australia. The majority of Southern Bluefin Tuna farming in Australia occurs in waters off Port Lincoln.

nullPreferred industry production system

Southern Bluefin Tuna are caught in the Southern Ocean, transferred to Port Lincoln and put in sea-cages to grow. The pontoons and nets are designed to maximise water flow and minimise marine growth and are regularly monitored by dive teams to maintain the structures integrity.
