Tuna farming is a relatively new industry having only started in the early 1990s in Port Lincoln, South Australia.
After being captured by purse seine net the tuna are transferred alive to a towing net and are towed to waters near Port Lincoln taking some 20 days, where they are swum through into other smaller cages.
During this transfer stage the fish are filmed so that they are accounted for TAC quota purposes.
Tuna arrive in January to March and are fed up to 6 days per week, twice a day (weather permitting).
The tuna live on a bait fish either fresh caught or frozen blocks that are thawed in a wire mesh feeding cage.
