Cleanseas Tuna in South Australia says its fish are now ready for reproduction in a carefully-controlled artificial environment.
The conditions are designed to mimic wild migration conditions for tuna.
Hatchery manager Morten Deichmann is optimistic.
"As a scientist and as a fish farmer this is probably the most exciting thing in the world right now," he said.
Cleanseas chairman Hagen Stehr says human control of tuna from conception to harvest would be a big step.
"We are definitely on the brink of revolutionising the industry," he said.
