sbt update

As previously announced to the market, Clean Seas achieved a world first for SBT when it successfully
transferred 149 juvenile SBT fingerlings into a sea cage in March 2011. The high transfer survival rate
was extremely pleasing as was the growth of the juveniles until they naturally succumbed to the cold
ocean temperatures. The fact that the oldest fish survived to some 160 days post hatch in declining
water temperatures bodes well for the coming seasons. The Company is particularly pleased with the
lighting and diet trials that were conducted. The lessons learned from these will be instrumental to the
future commercial success of the project.
The Company?fs aim is to bring the spawning season forward year?]by?]year until the spawning
commences in October and juveniles are able to be transferred to sea cages when the water
temperatures are still on the rise. This will enable improved growth and the Company is confident that
greater survival will be achieved with bigger juveniles going into the winter months ?] as has been the
experience with the Northern Bluefin Tuna spawned in Japan.
Clean Seas is well underway with preparations for a December 2011 spawning cycle. In April of this year
a further 11 SBT broodstock were transferred into the on?]shore broodstock facility and they have settled
in well with the existing cohort and have been schooling tightly.
Furthermore, the program for planned SBT larval rearing over the 2011/12 summer is well advanced and
resourced and the Company?fs staff is motivated to improve on the success of the 2011 season. Trials
this season will concentrate on early larval rearing survival, live feeds and earlier weaning.
The Company continues to be the key private participant in Seafood CRC Ltd and this relationship is
supported by an Industry Partnership Agreement with Fisheries Research and Development Corporation
(FRDC). Extensive SBT research programs for the coming three years have been developed with the CRC
and FRDC to complement the Company?fs own research and development activities, facilities and
personnel. Dr Bennan Chen has been appointed as the Research & Development Manager for the
remainder of the CRC program. Dr Chen, who previously was employed by SARDI, has been working for
SARDI on the project team over the past three years. He brings us considerable research experience as
well as practical larval rearing skills.
Clean Seas will continue its research relationships with Kinki University, SARDI and NSW DPI. It is
pleasing to add that six of our employees have spent time with Kinki University during their Northern
Bluefin Tuna larval rearing season of July/August 2011 and we look forward to welcoming back the Kinki
University researchers during our spawning season.
Overall, the Company is confident that it will achieve significant progress with SBT juvenile production at
both Arno Bay in South Australia and at its research partner sites. It is expected that a greater number
of SBT fingerlings will be successfully transferred to sea cages for experimental grow out in 2012.
