| 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. |
| They are ready to be harvested when they obtain a growth rate of 40%. |
