 However, after experiencing financial difficulty, the board of Clean Seas decided during December 2012 to defer its tuna propagation research and write-off the value of the intellectual property it developed as part of its research into SBT propagation.According to the Chairman and Chief Executive's report for the financial year ending 30 June 2013, the production of SBT juveniles had been slower and more difficult than anticipated.Clean Seas will maintain its broodstock to enable discrete research in the future, however they do not expect commercial production to be achieved over the short to medium term.
