According to ABC News, the company's chairman, Hagen Stehr, said the company was forced to make the announcement earlier than planned after a jump in its share price on Monday.
The company halted trading for about two days after the share price rose by 38 per cent, reported the news agency earlier today.
Mr Stehr says the life-cycle of the tuna is now complete, with enough eggs and larvae to produce tuna for the next 18 years.
"We've got virtually unlimited amount of fertilised eggs," he said.
"That means that we've got fertilised eggs, we've got larvae, we've closed the cycle, and we're now looking for commercialisation.
