Economics of Ocean Culture of Giant Clams, Tridacna-Gigas - Internal Rate of Return Analysis

摘要: The paper estimates the internal rate of return investment in a giant clam farm involved ocean phase mariculture as function period growout Tridacna gigas. is assumed each year to place 100 000 seed clams approximately 1 age. optimal length time hold them depends on farm-gate price meat and estimated be 11 years when they are sold at $A5 per kg. This yields an 18.0% maximises net present value or capitalised farm. If 40% drip loss occurs 11.25% batches 14 years.
