Evaluation of Status and Competitive Advantage of Tuna Aquaculture in Australia

摘要

Tuna have been an important food resource for humans since ancient times. While the harvest of wild-caught bluefin has been decreasing, the production of cultured bluefin tuna has been increasing rapidly (Sylvia 2004). Total bluefin production is around 65,000 tonnes a year and, of this, cultured tuna production is now around 30,000 tonnes (Joseph 2003). Given that fisheries regulations to preserve the wild bluefin resource will be strengthened further, it is expected that cultured tuna as a substitute for wild bluefin will become more important in the near future.
