Clean Seas SBT world first

Australia: Clean Seas Tuna has become the first company to successfully transfer a batch of Southern Bluefin Tuna fingerlings from onshore nursery tanks to a sea cage for controlled grow-out trials. Some 90 fingerlings, now ranging in length from eight to ten centimetres, and weighing up to 15 grams, have been transferred to a 25-metre-diameter cage offshore. The transfer followed the successful weaning of the fingerlings onto a manufactured diet. A similar number of fingerlings will remain in the onshore nursery tanks at the company’s Arno Bay facility in Port Lincoln, Australia, while the at-sea development is assessed.
