Economic feasibility study of Litopenaeus vannamei shrimp farming: nanobubble investment in increasing harvest productivity

摘要: This study aimed to evaluate the economic feasibility of Litopenaeus vannamei shrimp reared at 400 shrimp/m2 in 56 days culture. The experimental design was set an 800 m2 HDPE pond installed with nanobubble and non-nanobubble. Shrimp survival total harvest treatment increased 92% 2,255 kg, respectively. Economic parameters calculated this were Net Present Value (NPV), Internal Rate Return (IRR), Payback Period (PP), Break Even Point (BEP), Benefit Cost Ratio (B/C Ratio), Sensitivity Analysis (SA). investment required run farming practice is IDR 182,887,700. Total revenue per cycle estimated 157,850,000 selling price 70,000/kg shrimp. PP 4 cycles, NPV 172,329,247 projected 10 cycles. IRR 18% BEP reached after 7,058 kg production B/C be 1.26 SA showed that productivity most affecting present analysis. Based on study, associated system feasible realized.
