As a result of estimating the net present value (NPV) and internal rate of return (IRR) using the cash flows (including depreciation) generated for 10 years in units of the business period (1 year). For the caught juvenile, NPV showed a positive value and IRR exceeded the social discount rate of 4.5%.
On the other hand, in the case of imported, NPV had a negative value and IRR was less than 4.5% of the social discount rate. Therefore, it was found that there is a business possibility to cultivate T. orientalis with juvenile caught at the offshore farm in Yokjido has business potential.
