 Initially, difficulties in closing the life cycle of the species dissuaded most from farming them.However, in 2007, using hormonal therapy developed in Europe and Japan (where they had already succeeded in breeding northern Pacific bluefin tuna to third generation) to mimic the natural production of hormones by wild fish, researchers in Australia managed for the first time to trigger spawning in landlocked tanks.This was done by the Australian aquaculture company, Clean Seas Tuna Limited.
