Great posts Algen and Inchiqin, even though Inchiqin apparently sees a slight difference in view - actually I don't see that your views are that different!

I'd like to make a further comment (albeit with my limited research on the subject - I'd appreciate and welcome anyone with more knowledge on the subject to make comment) on the biological risk with the prawns that Inchiqin refers to - and yes it is understood that such a risk will always require considerable vigilance to ensure biosecurity is not breached.
Firstly one of the biggest benefits that COZ holds is that with the various ponds at different locations - with Seafarms and Coral Seafarms being kilometres apart, plus the breeding site at Exmouth thousands of kilometres away, this ensures that biosecurity will be appreciably enhanced.
Secondly, SE Asian prawns are under constant threat of biological disease, thus forcing up the price of prawns and encouraging the farming of prawns at more biologically secure distant locations such as Australia. This is a prime reason why Project Sea Dragon should ultimately get the nod, subject to financing and government facilitation of various regulatory hurdles.
Thirdly, once Novaq does become commercially available and becomes a standard feed for tiger prawns, apparently this will reduce disease risk.

From my understanding of Clean Seas Tuna, the biggest issue in the past was its intention to develop a major yellowfin tuna farming industry, and ultimate successful breeding and rearing of the tuna failed. Its latest foray was to substitute kingfish for tuna, and this has been successful, albeit currently at a scale that requires further production increases to improve its profitability - it has benefited by R & D tax concessions to date.
