in for a good week for aus tuna industry, page-3

I think your spot on on many of your points. They have closed the life cycle of many fish species as aquaculture is the fastest growing animal food product globally. The point with SBT is that it is rare compared to many of the other fish they use for sushi/sashimi. Im pretty sure they regard it more as a delicacy (it tastes better apparently, never tasted it myself). It receives a higher price than other tuna, such as yellow fin, pacific blue fin etc. But like you say it is supply and demand, and eventually as others get into the industry it will be like the salmon industry in say Norway, where margins have shrunk and profit is the difference between food/labour and the market price. I think that this will take a long time though and CSS will have a monopoly. But, as always where theres large margins others people will try to take a piece of that. To get something like this right takes a while, especially larval rearing from hatching on to dry feed. For example the atlantic cod industry has been putting in a determined effort to ironing out problems for 10 years plus now, and first feeding diets are only just starting to give good replicatable results. As the price of wild caught cod has increased in recent years they margins are greater and the effort becomes greater, hence there has been a more dramtic acceleration in the last couple of years. I read through some stuff yesterday on other tuna rearing and the problems they had initially were not unlike other fish species and as such i believe that SBT will not be to any degree harder to successfully farm. On saying this i have never worked with SBT or any other tuna species, and so this is an assumption on my part
