(Business management status and the cost structure of yellowtail aquaculture)

The business of yellowtail aquaculture (individual operators) has continued to be in deficit since 2008. Corporate operators were in surplus in FY2010 and FY2011, but turned to record a deficit of 23.42 million yen in FY2012. The percentage of feed and seed costs in the total cost is high at around 80% for individual operators and more than 70% for corporate operators.

The unit price tends to drop two years after a year when a large amount of seeds have been introduced. For well-planned business management of yellowtail aquaculture, it is necessary to consider the amount of seeds to be introduced with an eye to the demand two years later, which is the time required from seed introduction until shipping.
